Description

A kind of wallpaper base paper and preparation method thereof
Technical field
The present invention relates to wallpaper base paper Material Field field, and in particular to a kind of wallpaper base paper and preparation method thereof.
Background technology
Common material when wall paper is current wall surfacing.When socket leaks electricity or has open fire, the resistance of metope wallpaper base paper Fuel efficiency fruit can prevent the sprawling of fire.Wallpaper base paper is the main base material of flame wallpaper production, can be carried out in wallpaper base paper Coat fire-retardant glue-line, painted, stamp, embossing, be fabricated to exquisite flame wallpaper, but existing flame wallpaper cannot be done To two-sided fire-retardant, the one side for often coating fire-retardant glue-line can be fire-retardant to open fire, but the one side of wallpaper base paper is not fire-retardant.Existing resistance It is as follows to fire the main reason for wallpaper base paper flame retardant property is undesirable.
Firstly, since hard copy body has the characteristics that combustible, the existing practical highest flame retardant rating of flame-retardant wallpaper base paper can only Reach that B2 grades flammable or B3 grades inflammable.When there is open fire, existing flame-retardant wallpaper base paper still can burn rapidly, can not actually play Fireproof flame-retardant effect, there are larger security risks.
Secondly, in the production of existing flame-retardant wallpaper base paper, mostly using fire retardant chemistry fiber or with fire-retardant latex as raw material To improve the anti-flammability of flame-retardant wallpaper base paper, but fire retardant chemistry fiber and fire retardant glue breast are expensive, and fire retardant chemistry per ton is fine Dimension, fire retardant glue breast valency lattice are up to ten thousand yuan or more, compared to there are huge on cheap, not fire-retardant chemical fibre and latex price Gap causes flame-retardant wallpaper base paper production cost excessively high, lacks the market competitiveness.
Finally, it is directly mixed into slurry the prior art mainly adopts fire retardant and base paper semi-finished product is made, rear Dipped latex Mode produce flame-retardant wallpaper base paper.But the wallpaper base paper flame retardant effect that existing method obtains is not lasting, and whiteness mistake It is low.When being often detected to the base paper just produced, wallpaper base paper can have preferable flame retardant effect and higher whiteness; But when being put into after warehouse 3-7 days sampling Detection again, wallpaper base paper, which can lead to the problem of flame retardant property, reduces or loses anti-flammability.
In addition, in order to adapt to the needs of special space environment, such as the field that hospital, school be crowded and bacterium is easily propagated Institute, the wallpaper as decorative material for internal wall should have the function of antibacterial.Chinese patent 201210147905.2 discloses one Kind antibacterial wallpaper and preparation method thereof, uses inorganic silver antibacterial agent to be added in ink, plays the effect of antibacterial.The method is adopted With the very high inorganic silver antibacterial agent of cost, many consumers can not bear its fancy price, therefore, people there is an urgent need to A kind of new good and cheap antibacterial wallpaper.
In summary, the use of wallpaper matrix is very crucial, and existing wallpaper matrix there is flame retardant effect difference and not Anti-flammability, deficiency of high cost and poor antibacterial can be kept for a long time.
Invention content
The object of the present invention is to provide a kind of low-cost wallpaper base paper, its not only good flame retardation effect, and can be long when Between keep anti-flammability it is fire-retardant, also there is antibacterial.
Another object of the present invention is just to provide a kind of preparation method of above-mentioned purpose mesospore paper substrate paper.
It is realized the purpose of the present invention is technical solution in this way, a kind of wallpaper base paper, including following parts by weight Component:20~35 parts of bamboo fibre, 15~75 parts of gou-tree fibre, 10~25 parts of sodium carboxymethylcellulose, acrylic latex 12~18 Part, 2~4 parts of fire retardant, 2~4 parts of modifying agent.
Further, acrylic latex is acrylic latex KJR-01.
Further, fire retardant is trihydroxy methyl phosphorous oxide or diphenyl phosphoester.
Further, modifying agent is dimethyl tin oxide or/and dibutyl tin dichloride.
It is realized it is another object of the present invention to technical solution in this way, a kind of production method of wallpaper base paper, Step is:
S1 adds in the water that weight is 85-108 times, is beaten, beaten with beater after mixing bamboo fibre and gou-tree fibre The degree of beating is controlled in 60~62OSR;
S2 adds in sodium carboxymethylcellulose and is stirred evenly in mixed serum;
Mixing slurry is made base paper semi-finished product by S3 by copy paper, squeezing, drying, coiling process;
Fire retardant and modifying agent are mixed evenly and obtain modified flame-retardant liquid, modified flame-retardant liquid is stood by S4 in mass ratio It adds in acrylic latex and stirs evenly acquisition glue application solution;
S5, base paper semi-finished product dipping and gluing liquid on sizing coating machine, dip time 8~22 minutes, dipping temperature 25~ 48℃;
Then S6 dries glue by hot air circulating system at 250~280 DEG C to the glue application solution permeated in base paper semi-finished product Change, batched through surface machinery calendering, 92~116g/m of paper grammes per square metre is made into2Wallpaper base paper.
A kind of wallpaper base paper of the present invention, bamboo fiber products have natural antibacterial, antibacterial, sterilization effect, because of bamboo The inside has a kind of unique substance, which is named as " bamboo a kind of jade ", has the function of naturally antibacterial, anti-mite, deodorization, insect prevention. Observe under the microscope, bacterium in the fibres such as cotton, wood can amount reproduction, and the bacterium on bamboo fiber products is not only not It can survive for a long time, and can also disappear or reduce in the short time, bacterial death rate is up to more than 75% in 24 hours.Japanese authority The new discovery of mechanism increases this value-added content of product, by Chinese Cotton Piece Goods product weight Supervision Test Center and China The detection of Shanghai institute of microbiology of the academy of sciences also demonstrates that (it is on bacterium is thousands of that cotton towel is easily smelly in summer to result above The result of ten thousand times of procreations).Bamboo fibre and gou-tree fibre are the preferable natural plant fibres of anti-microbial property, while use more can be mutual It mends, reaches preferably sterilization, fungistatic effect.
Acrylic latex is the acrylic latex that acrylic latex KJR-01 is Xi'an Daoerda Chemical Co., Ltd.'s production, Its excellent weatherability and resistance to ag(e)ing has remarkable copolymerized ability.
Trihydroxy methyl phosphorous oxide and diphenyl phosphoester and modifying agent dimethyl tin oxide, dibutyl tin dichloride are modified There can be stable, excellent flame retardant property.The present invention is by the way that fire retardant and modifying agent are mixed in mass ratio in step Even acquisition modified flame-retardant liquid, modified flame-retardant liquid is added in immediately in acrylic latex and stirs evenly acquisition glue application solution;Modifying agent Higher activity is stably held in using fire retardant is made.Latex plays the role of modified flame-retardant liquid package, keeps modified flame-retardant The active permeation of liquid is into the fiber hole of wallpaper base paper;With existing expensive fire-retardant latex and fire retardant chemistry fiber phase Than fire retardant and modifying agent are cheap used in the present invention, and the fire retardant effects of B1 are can reach with the collocation of not fire retardant chemistry fiber Fruit.Method using the present invention, by the cost of flame-retardant wallpaper base paper, can be reduced to existing flame-retardant wallpaper base paper cost 30~ 40%, the prominent market competitiveness is obtained in price.
By adopting the above-described technical solution, the present invention has the advantage that:Its not only good flame retardation effect, and can growing Time keeps the fire-retardant of anti-flammability, also has effects that good antibacterial, antibacterial.
