Description
Defensa para barcos.
La presente invención se refiere a un parachoques
marino que comprende una placa de resina sintética con propiedad de
deslizamiento superior sobre la superficie exterior del parachoques.
El parachoques marino de acuerdo con el preámbulo a la
reivindicación 1 está descrito en el documento GB 2 088 524 A.
Los ejemplos utilizados como parachoques marinos
para absorber un impacto cuando se atraca un barco en el muelle
incluyen un parachoques marino que comprende un elemento de
parachoques de caucho y una placa de polietileno de peso molecular
ultra-alto (UHMW-siglas en inglés)
dispuestos en por lo menos una parte de las superficies del elemento
de parachoques de caucho.
Convencionalmente, el parachoques marino
comprende el elemento de caucho y la placa de polietileno de peso
molecular ultra-alto (UHMW-siglas en
inglés) que está sujeta al elemento de parachoques de caucho
mediante pernos de tal manera que la cabeza de cada perno está
situada dentro de la concavidad formada en la placa de polietileno
de peso molecular ultra-alto
(UHMW-siglas en inglés). La razón porque la cabeza
del perno está situada dentro de la concavidad consiste en el hecho
de que se intenta prevenir que el casco del barco entre en contacto
directo con la cabeza del perno. Sin embargo, la placa de
polietileno de peso molecular ultra-alto
(UHMW-siglas en inglés) se nivela con la cabeza del
perno debido al desgaste de la superficie del polietileno de peso
molecular ultra-alto (UHMW-siglas en
inglés). En tal caso, el casco del barco entra directamente en
contacto con la cabeza del perno y por lo tanto queda dañado.
En el documento JPA 5-59711 está
descrito un parachoques marino que comprende un elemento de
parachoques de caucho y un film de polietileno de peso molecular
ultra-alto (UHMW-siglas en inglés)
que está unido al elemento de parachoques de caucho mediante
soldadura. En detalle, el film de polietileno de peso molecular
ultra-alto (UHMW-siglas en inglés)
cuyo espesor se encuentra entre 50 \mum y 10 mm, y el elemento de
parachoques de caucho que está compuesto de un molde de caucho no
vulcanizado, están bajo la presión de 5-20
kg/cm^{2} en la temperatura de 130-150ºC y están
vulcanizados para unir el film de polietileno de peso molecular
ultra-alto (UHMW-siglas en inglés)
con el elemento de parachoques de caucho.
En el caso de que el film de polietileno de peso
molecular ultra-alto (UHMW-siglas en
inglés) y el elemento de parachoques de caucho estén unidos por
medio de la vulcanización según está descrito en el documento JPA
5-59711, es imposible aumentar suficientemente el
film de polietileno de peso molecular ultra-alto
(UHMW-siglas en inglés). La vulcanización entre el
caucho y el polietileno de peso molecular ultra-alto
(UHMW-siglas en inglés) requiere la temperatura de
130-150ºC. Resulta difícil calentar toda la
superficie de unión en la temperatura de 130ºC ó más cuando el film
de polietileno de peso molecular ultra-alto
(UHMW-siglas en inglés) está unido a un molde grande
como el elemento de parachoques. Es decir, la temperatura alrededor
del centro de la superficie de unión tiene la tendencia de ser más
baja que 130ºC y así causa una unión incompleta. Este hecho reduce
la fuerza de fijación del film de polietileno de peso molecular
ultra-alto (UHMW-siglas en inglés) y
su vida útil.
Constituye el objetivo de la presente invención
solucionar las deficiencias mencionadas con anterioridad y
proporcionar un parachoques marino que tenga un gran poder adhesivo
del encolado entre la placa de resina sintética que tiene las
propiedades de fricción bajas ó altas propiedades de deslizamiento
(de aquí en adelante llamada "la placa de resina sintética de
deslizamiento superior") como la placa de polietileno de peso
molecular ultra-alto (UHMW-siglas en
inglés) y el elemento de parachoques de caucho y que tiene bastante
larga vida útil de la placa de resina sintética de deslizamiento
superior.
El parachoques marino de la presente invención
comprende un elemento de parachoques de caucho y una placa de resina
sintética que se encuentra por lo menos en una parte de la
superficie exterior del elemento del parachoques de caucho. La placa
de resina sintética de deslizamiento superior tiene una capa de
caucho soldada a la superficie posterior de la misma y la capa de
caucho está unida con el elemento de parachoques de caucho.
En el parachoques marino de la presente
invención, la placa de resina sintética de deslizamiento superior
que tiene la capa de caucho soldada a la superficie posterior de la
misma puede estar sujeta a la superficie exterior del elemento de
parachoques de caucho por medio de la vulcanización.
En el parachoques marino de la presente
invención, la placa de resina sintética de deslizamiento superior
que tiene propiedades de fricción bajas tales como la placa de
polietileno de peso molecular ultra-alto y el
elemento de parachoques de caucho están fuertemente sujetas por
medio de la superficie de unión que se encuentra entre las mismas.
Esto quiere decir que, cuando la capa de caucho está soldada a la
placa de resina sintética de deslizamiento superior, el espesor de
la capa de caucho es considerablemente más pequeño que él del
elemento de parachoques de caucho para que la superficie entera
entre la capa de caucho y la placa de resina sintética de
deslizamiento superior puedan ser calentadas hasta la temperatura de
145ºC ó más, proporcionando de esta manera una sujeción fuerte en
toda la superficie de unión. Cuando la resina sintética de
deslizamiento superior, a cuya superficie posterior está unida la
capa de caucho, está soldada al elemento de parachoques de caucho
por medio de la vulcanización, es suficiente que la superficie de
unión entre la capa de caucho y el elemento de parachoques de caucho
esté calentado hasta la temperatura de 110ºC ó más. En tal
temperatura, la superficie de unión puede ser totalmente calentada
incluso cuando el elemento del parachoques de caucho sea
relativamente grande. Por lo tanto, la capa de caucho y el elemento
de parachoques de caucho están fuertemente sujetos en toda la
superficie de unión.
De acuerdo con la presente invención, incluso si
el espesor de la placa de resina sintética de deslizamiento superior
como la placa de polietileno de peso molecular
ultra-alto sea relativamente grande, la placa de
resina sintética de deslizamiento superior y el elemento de
parachoques de caucho pueden estar fuertemente unidos uno al otro.
Adicionalmente, el parachoques marino puede ser utilizado sin
problema a no ser que la placa de resina sintética de deslizamiento
superior se desgaste casi por completo.
La rugosidad de la superficie de la capa de
caucho que se vaya a unir con el elemento de parachoques de caucho,
aumenta más aún el poder adhesivo del encolado entre la capa de
caucho y el elemento del parachoques de caucho.
Se procederá ahora a describir una realización,
solamente a efectos de ejemplo, con referencia a los dibujos
acompañantes, en los que:
La Figura 1 es una vista en perspectiva que
muestra un parachoques marino de acuerdo con la presente
invención.
Como está presentado en la Figura 1, el
parachoques marino 1 comprende un elemento de parachoques de caucho
2, una capa de caucho 3 y una placa de resina sintética 4 con
propiedades de deslizamiento superior (de aquí en adelante llamada
"la placa de resina sintética de deslizamiento superior") que
está unido con el elemento de parachoques de caucho 2 a través de la
capa de caucho 3.
Para fabricar el parachoques marino 1, la placa
de resina sintética con deslizamiento superior que tiene propiedades
de fricción bajas 4 y la capa de caucho 3 están previamente soldadas
una con la otra. La placa de resina sintética de deslizamiento
superior 4 con la capa de caucho 3 se sujeta entonces al elemento de
parachoques de caucho 2 por medio de la vulcanización.
Un ejemplo preferente de la placa de resina
sintética de deslizamiento superior es una placa de polietileno de
peso molecular ultra-alto
(UHMW-siglas en inglés).
El espesor de la placa de resina sintética de
deslizamiento superior se encuentra preferentemente en el rango
entre 10 y 100 mm, especialmente entre 30 y 50 mm. Utilizando la
placa de resina sintética de deslizamiento superior de este espesor
se extiende la vida útil del parachoques marino.
El espesor de la capa de caucho es
preferentemente fino, encontrándose entre 1 y 50 mm, especialmente
entre 1 y 5 mm. Utilizando tan fina capa de caucho hace posible que
toda la superficie de unión entre la capa de caucho 3 y la placa de
resina sintética de deslizamiento superior se pueda calentar en la
temperatura de 145ºC ó más para proporcionar una soldadura fuerte a
través de las mismas.
La temperatura de la soldadura del caucho y la
placa de resina sintética de deslizamiento superior se encuentra
preferentemente en el rango entre 145 y 160ºC, la presión para su
presurización está preferentemente en el rango entre 2 y 30
kg/cm^{2}, especialmente entre 2 y 10 kg/cm^{2}.
Es preferente que el elemento del parachoques
marino de caucho 2 esté previamente formado como un molde no
vulcanizado ó con baja vulcanización y posteriormente la placa de
resina sintética de deslizamiento superior 4 con una capa de caucho
3 esté soldada con el molde por medio de la vulcanización.
Es preferente que la superficie de la capa de
caucho 3 esté hecha rugosa por medio de pulimentación ó utilización
de tela antes de la vulcanización.
Los ejemplos de caucho como material de la capa
de caucho y el elemento de parachoques de caucho incluyen el caucho
natural (NR-siglas en inglés), caucho de
estireno-butadieno (SBR-siglas en
inglés), caucho de butilo (BR-siglas en inglés),
caucho de cloropreno (CR-siglas en inglés) y caucho
sintético de etileno propileno dieno monómero
(EPDM-siglas en inglés). El componente de caucho
contiene un acelerador de vulcanización y, si fuera necesario, un
relleno como negro de carbón, sílice y arcilla, antioxidante,
ayudante de procesamiento y suavizador.
La capa de caucho 3 y el elemento de parachoques
de caucho 2 están preferentemente hechos del mismo caucho.
La capa de caucho 3 que tiene el espesor de 5 mm
estuvo formada sobre la superficie trasera de la placa de
polietileno de peso molecular ultra-alto
(UHMW-siglas en inglés) 4 por medio de la soldadura
del caucho con la superficie trasera de la placa de polietileno de
peso molecular ultra-alto
(UHMW-siglas en inglés) (tamaño: 300% 300% 50 mm)
con la presión de 30 kg/cm^{2}, en la temperatura de 158ºC por el
periodo de 45 minutos.
Entonces, el molde no vulcanizado como el
elemento de parachoques de caucho del mismo componente de caucho
como la capa de caucho 3 y la placa de polietileno de peso molecular
ultra-alto (UHMW-siglas en inglés) 4
con la capa de caucho 3 fueron colocados uno encima de la otra y
sometidos al tratamiento térmico y presurizados bajo la presión de
30 kg/cm^{2}, en la temperatura de 150ºC por el periodo de 180
minutos. De este modo, la capa de caucho 3 y el elemento de
parachoques de caucho 2 fueron vulcanizados y soldados uno con el
otro.
El parachoques marino estuvo hecho de esta
manera. También se realizó en el parachoques marino el ensayo de la
resistencia al arrastre de la placa de polietileno de peso molecular
ultra-alto (UHMW-siglas en inglés)
4. Como resultado de este ensayo, se descubrió que la fuerza de
arrastre era de 30 kg/cm ó más.
Ejemplo Comparativo
1
Se hizo un parachoques marino de la misma manera
que en el Ejemplo 1 excepto el hecho de que el molde del elemento
del parachoques de caucho y la placa de polietileno de peso
molecular ultra-alto (UHMW-siglas en
inglés) 4 estaban directamente colocadas uno sobre la otra sin la
capa de caucho 3. Sin embargo, apareció en este caso una unión
incompleta en el parachoques marino.
Según se ha mencionado con anterioridad, en el
parachoques marino de acuerdo con la presente invención, la placa de
la resina sintética de deslizamiento superior que tiene un espesor
grande puede estar fuertemente unida al elemento del parachoques de
caucho por medio de la vulcanización. En este parachoques marino, no
se requiere ningún perno para fijar la placa de la resina sintética
de deslizamiento superior con el elemento del parachoques de caucho.
Por lo tanto, no existe la posibilidad que se deteriore el casco del
barco incluso si se desgaste completamente la placa de la resina
sintética de deslizamiento superior. No existe la posibilidad que el
casco del barco esté en contacto directo con el caucho porque la
placa de la resina sintética de deslizamiento superior se encuentra
sobre la superficie exterior del elemento del parachoques de caucho
así que el lado negro del caucho nunca se encuentra sobre el casco
del barco.
