Description
Technical Field
The invention relates to the technical field of coatings, in particular to a special liquid crystal ceramic paint for underwater decoration and protection.
Background
The concrete of the water world, the ocean and the swimming pool is subjected to chemical medium pool water soaking (mainly disinfectant water, copper sulfate and the like) and outdoor severe environment examination (mainly ultraviolet irradiation, solar explosion and temperature difference cold and heat cycle change); the technical requirements of environmental protection, corrosion resistance, antibiosis, water resistance and no delamination of the service life and underwater humid environment are difficult to meet without excellent material mechanical property and maintenance measures;
the chemical properties of the product obtained by the existing underwater paint preparation method and production process are not stable enough, so that the service life of the product is short; particularly, the problems of coating falling, blistering and the like caused by the double action of positive and negative water pressure in water and the phenomenon that tourists in the water world fall down carelessly in the surfing process are difficult to effectively solve in underwater coating.
Disclosure of Invention
The invention aims to provide a liquid crystal ceramic paint for underwater decoration and protection, which can be used in the water world, a marine museum and a swimming pool.
The invention also aims to provide a preparation method of the liquid crystal ceramic paint for underwater decoration and protection.
The special liquid crystal ceramic paint for underwater decoration and protection comprises the following components in parts by weight:
base material: 40-60
Auxiliary agent: 2-5
Pigment: 10-30
Filling: 15-40
Organic modified product: 90-120
The base material is epoxy modified resin;
the organic modifier is modified polyamide;
the auxiliary agent comprises a wetting agent, a dispersing agent, a flatting agent, a softening agent, anti-skid particles, an anti-settling agent and a defoaming agent which are compatible with the coating; the main function is to assist in the formulation of the paint and to provide a certain aspect of the product with properties or to improve a certain aspect of the product.
The pigment is high-temperature calcined pigment or high-temperature resistant pigment; pigments and fillers not only provide a wide variety of colors to the coating, but also enhance some of the properties of the coating itself, such as hardness, abrasion resistance, hiding power.
Further, the organic modifier is one or a mixture of more than two of modifiers selected from PA/PE, PA/PP, PA/ABS, PA/PC, PA/PBT, PA/PET, PA/PPO, PA/PPS, PA/I, PA/PA, PPO/PA6 and PPS/PA 66.
The epoxy modified resin is one or a mixture of more than two of modified substances of polysulfide rubber, polyamide resin, polyvinyl butyral, nitrile rubber, phenolic resin, polyester resin, urea-formaldehyde melamine resin, furfural resin, vinyl resin, isocyanate and silicone resin.
Further, a curing agent used for paint preparation of the coating is an M233-B curing agent, and the solid content of the M233-B curing agent is 100%.
Further, the wetting and dispersing agent is a high molecular block copolymer with pigment-philic groups or an acrylic polymer containing pigment affinity groups.
Further, the pigment is one or a mixture of more than two of titanium dioxide, titanium nickel yellow, bismuth vanadate yellow, chrome yellow, strontium yellow, manganese iron black, copper chromium black, iron titanium black, carbon black, cobalt blue, titanium chromium brown, iron chromium brown, chromium green, cobalt green, molybdenum chromium red, iron red, pearlescent pigment, aluminum silver paste, mica powder, transparent silicon dioxide and transparent aluminum oxide.
In order to achieve the second purpose, the following technical scheme is adopted:
the preparation method of the special liquid crystal ceramic paint for underwater decoration and protection comprises the following steps:
(1) preparing paint: sequentially adding epoxy modified resin, modified polyamide, wetting agent, dispersing agent and anti-settling agent into a stirring kettle, dispersing for 5min at medium speed, wherein the rotating speed of the stirring kettle is as follows: 1000 r/min; titanium dioxide and filler are added in sequence in the dispersion, and the high-speed dispersion is carried out for 20-30 min; the rotating speed of the stirring kettle is as follows: 1500r/min, and the detection fineness is less than or equal to 35 um; and finally, sequentially adding a flatting agent and a defoaming agent in the dispersion, dispersing at an intermediate speed for 5min, wherein the rotating speed of the stirring kettle is as follows: 1000 r/min.
(2) Ceramic surface treatment: the method comprises the steps of firstly carrying out wax removal and oil removal treatment on the ceramic surface, then using a high-pressure air spray gun to spray oxides, stains and sand dust on the ceramic surface, wherein the workpiece subjected to impurity removal treatment needs to be sprayed within 1 hour, and the sand dust weather needs to be shortened as much as possible.
(3) Construction: mixing the main paint and the curing agent according to the ratio of 3.4:1, filtering the mixed paint by using a 200-300-mesh filter screen, adding the filtered paint into a spray gun, spraying under the normal air condition, adopting quick thin spraying when spraying for the first time, controlling the thickness to be 25-30um, directly spraying for the second time after naturally cooling for 5min, controlling the thickness to be 20-25 um according to the requirement, and cooling for 4 hours in the natural environment; and after spraying, the spray gun is cleaned by ethyl acetate.
