Description
Technical field
The present invention relates to a kind of wallpapers, and in particular to a kind of Edge curl preventing PVC wallpaper and preparation method thereof.
Background technology
With the development of economy with the raising of living standards of the people, diversified building and ornament materials have been enter into household and
The use of office space, current market sales of wallpaper include mainly PVC wallpaper, pure paper wallpaper, diatomite wallpaper, wood-fibred
Wallpaper, natural fabric wallpaper etc., wherein since PVC wallpaper has designs and varieties abundant, scrubbing resistance, anti-aging, not fugitive color etc.
Advantage, and it is moderate, it is more welcome on the market, therefore the product of PVC wallpaper is more.
But because PVC wallpaper is made of PVC material and paper substrate layering, rear paper substrate can be swollen because of water on pasting wall
Swollen, and the PVC material of paper will not be expanded because of water, then, paper substrate expands outward and when paper difference expands, therefore is easy for
Cause crimping.Meanwhile the wallpaper variation with temperature of PVC material and retractility is bigger, and paper substrate variation with temperature compares
Small, this also be easy to cause the crimping of PVC material.In addition, since PVC wallpaper is airtight, the moisture in wall and work progress is all
It seals in the inside, just as having worn a plastics clothes, goes mouldy once condition is properly easy for generating.
Invention content
The purpose of the present invention is to provide a kind of Edge curl preventing PVC wallpapers, it is rolled up after wallpaper can not only be avoided to paste
While fall off, and it is of low cost, can be fire-retardant and avoid going mouldy；It is a further object of the present invention to provide a kind of Edge curl preventing PVC walls
The preparation method of paper, can be cost-effective when making Edge curl preventing PVC wallpaper, improves efficiency.
It is realized the purpose of the present invention is technical solution in this way, a kind of Edge curl preventing PVC wallpaper, including base paper, PVC
Material, PVC material include the component of following parts by weight：100~180 parts of PVC monomers, CaCo37.5~18 parts, short glass fiber 8
~21 parts, 4~10 parts of water-absorbing resin, 6~10 parts of rhenocure CA, absorb water 0.3~0.7 part of auxiliary agent, 0.3~0.5 part of stearic acid,
ZnO2~4 part, 5~14 parts of bulking agent, 1~6 part of mould inhibitor, 8~15 parts of dispersant, 5~12 parts of o-phthalic acid dibutyl ester, sulphur
16~25 parts of agent, 3~10 parts of antioxidant, 4~15 parts of fire retardant.
In the present invention, vulcanizing agent makes to reticulate with covalent bond connection between line style or branch type macromolecular chain between PVC monomers
Or three-dimensional polymeric molecule, solved after crosslinking the unstability structure such as branch, double bond, allyl chloride, tertiary chlorine in PVC macromoleculars, to
Achieve the purpose that heat-resistant deforming, PVC is reduced jointly at different temperatures with short glass fiber and rhenocure CA heat stabilizer
Retractility；Water-absorbing resin, water suction auxiliary agent, stearic acid and ZnO form absorbent composition, but since PVC and short glass fiber inhale
Aqueous difference, and absorbent composition good water absorption lead to the poor compatibility of the two.Make PVC and short glass fiber with physical blending process
Differ larger with the property of PVC and short glass fiber due to absorbent composition when being blended with absorbent composition so that absorbent composition is very
It is easy to be precipitated, be expanded jointly with base paper to be unfavorable for PVC material；In order to solve the problems, such as that the two poor compatibility, the present invention add
Enter bulking agent to improve the binding force between absorbent composition and PVC；CaCo3As the filler of PVC material of the present invention, mould inhibitor,
The effect of antioxidant and fire retardant is antimildew and antibacterial respectively, anti-aging and fire-retardant；When solid abrasive, dispersant is added, contributes to
Particle crushes and prevents broken particle cohesion and keeps dispersion stable；The effect of o-phthalic acid dibutyl ester is to increase PVC materials
The flexibility and gas permeability of material, and increase polymer and compatibility when additive batch mixing, avoid PVC material from being broken.
Obtain can be expanded in a wetted condition with base paper and the smaller PVC material of variation with temperature bonded with base paper to be formed it is anti-
Crimping PVC wallpaper.
Further, vulcanizing agent is polyvinylchloride crosslinking agent FASH.
Further, water-absorbing resin is MA-VAC and MA-VAC-MMA copolymers.
It is realized it is another object of the present invention to technical solution in this way, a kind of Edge curl preventing PVC wallpaper, feature exists
In the preparation method of the wallpaper is：
1）, water-absorbing resin, water suction auxiliary agent, stearic acid, ZnO, vulcanizing agent are added in blender with 100 by above-mentioned number value~
The mixing speed of 200r/min stirs 10~15min, and PVC monomers, short glass fiber, CaCo is then added3, blender with
The mixing speed of 800~1300r/min stirs 20~30min, finally by bulking agent, rhenocure CA, mould inhibitor, O-phthalic
Sour dibutyl ester, antioxidant and fire retardant be added in blender the mixing speed with 2000~3000r/min stirring 10~
15min obtains PVC paste agent；
2）, it being ground being put on three-roll grinder after PVC paste agent addition dispersant, grinder slow rollers rotating speed is 32r/min,
Central roll rotating speed is 89r/min, fast roller 250r/min；
3), then the PVC paste agent after grinding is put into blender the moderate-speed mixer with 400~700r/min and mixes 30~50 minutes；
4), PVC paste agent will be uniformly applied to base paper layer upper surface with painting cloth-knife after moderate-speed mixer；
5）Gelatinization processing is carried out to base paper face coat using the hot air circulating system of gas heater；
6）Hardening by cooling is carried out to the hot fabric that gelatinization is handled with circulated refrigerated water by cooling wheel and obtains Edge curl preventing PVC wallpaper.
