Summary of the invention
The object of the invention just provides wall fitting wallpaper material of a kind of environmental protection and preparation method thereof.
Realize that the technical scheme that above-mentioned purpose of the present invention adopted is:
A kind of environment-friendly type wall fitting wallpaper material is characterized in that: be made up of original paper layer and the coat that adheres on its single or double; Described coat includes the PE plastics of 60-90 weight portions and the thermoplasticity EPDM dynamic perduren of 15-25 weight portions.
The additional technical feature that constitutes above-mentioned a kind of environmental protection wall fitting wallpaper material comprises:
Described coat contains the fire retardant of 0.1-0.5 weight portion;
The density of said PE plastics is between 0.88-0.92 gram/cubic centimetre;
The thickness of said coat be 55-65 the gram/square metre.
The method for preparing above-mentioned environmental protection wall fitting wallpaper material comprises the following steps:
Body paper is unreeled, and through the sided corona treatment paper, the PE plastics that will contain thermoplasticity EPDM dynamic perduren and fire retardant are heated to 340-380 ℃ and form and flow film on paper after liquid and form cover layer, oven dry back rolling.
A kind of environmental protection wall fitting wallpaper material provided by the present invention and preparation method thereof compared with prior art has the following advantages: one of which; Because constituting the coat of the structure of this its wall fitting wallpaper material is to be made up of the PE plastics that added thermoplasticity EPDM dynamic perduren therein; These PE plastics are a kind of asepsis environment-protecting materials, and the decorative wall paper material that is therefore constituted has the characteristics of asepsis environment-protecting; They are two years old; Owing to itself be mixed with the starch that to degrade in the PE plastics; Therefore, the decorative wall paper material that is constituted accomplish the fixing use age can natural degradation after being eliminated, solved a large amount of waste and old decorative wall paper materials in back that update and caused environmental pollution problems; Its three comprised PE plastics that molecular weight is moderate and an amount of TPV macromolecular elastomer material in the material of above-mentioned environmental protection wall fitting wallpaper material coat owing to constitute, make that the direct colour print performance of wall fitting wallpaper material is better.
The specific embodiment
Below in conjunction with accompanying drawing the structure and the use principle of environmental protection wall fitting wallpaper material provided by the present invention are done further to specify:
As depicted in figs. 1 and 2 is the structural representation of environmental protection wall fitting wallpaper material provided by the invention.The structure that promptly constitutes this environmental protection wall fitting wallpaper material comprise by original paper layer 1 with adhere to its lip-deep coat 2 that constitutes by PE plastics and thermoplasticity EPDM dynamic perduren and constitute; Or coat 2 is coated on the coat 2 on original paper layer 1 two sides.
The preparation technology of above-mentioned environmental protection wall fitting wallpaper material may further comprise the steps:
1, body paper unreels, and handles the body paper first surface through corona technology;
The PE plastics that 2, will contain thermoplasticity EPDM dynamic perduren and fire retardant be heated to 340-380 ℃ form liquid back through the stream membrane process through form on the paper of sided corona treatment thickness 55-65 grams/square metre coat;
3, oven dry;
4, rolling.
When the second surface at body paper prepares coat; Repeat first and second operations after second step in above-mentioned operation; Promptly at first handle the body paper second surface through corona technology; The PE plastics that will contain thermoplasticity EPDM dynamic perduren and fire retardant then be heated to 340-380 ℃ form liquid back through the stream membrane process through form on second paper of sided corona treatment thickness 55-65 grams/square metre coat, get final product through oven dry, rolling again.
In above-mentioned preparation technology, are continuous scopes to the heating-up temperature scope of the PE plastics that contain thermoplasticity EPDM dynamic perduren and fire retardant, and adjust according to the content of various compositions is different.
The formation that constitutes above-mentioned environmental protection wall fitting wallpaper material coat is that embodiment is:
1, density is 60 weight portions at the PE of 0.88-0.90 gram/cubic centimetre plastics, thermoplasticity EPDM dynamic perduren 25 weight portions.
2, density is 90 weight portions at the PE of 0.88 gram/cubic centimetre plastics, thermoplasticity EPDM dynamic perduren 15 weight portions.
3, density is 75 weight portions at the PE of 0.90 gram/cubic centimetre plastics, thermoplasticity EPDM dynamic perduren 20 weight portions.
4, density is 80 weight portions at the PE of 0.88-0.90 gram/cubic centimetre plastics, the Firemaster CA 117 of thermoplasticity EPDM dynamic perduren 18 weight portions and 0.5 weight portion.
5, density is 70 weight portions at the PE of 0.88-0.90 gram/cubic centimetre plastics, the fire retardant BS5852 of thermoplasticity EPDM dynamic perduren 20 weight portions and 0.1 weight portion.
6, density is 65 weight portions at the PE of 0.88-0.90 gram/cubic centimetre plastics, the fire retardant that the LM-BS1 flame-proof environmental protection particle of thermoplasticity EPDM dynamic perduren 22 weight portions and 0.3 weight portion (Foshan be full of intelligence chemistry Co., Ltd produce) constitutes.
7, density is 65 weight portions at the PE of 0.92 gram/cubic centimetre plastics, thermoplasticity EPDM dynamic perduren 20 weight portions.
8, density is 75 weight portions at the PE of 0.90 gram/cubic centimetre plastics, thermoplasticity EPDM dynamic perduren 18 weight portions.
9, density is 85 weight portions at the PE of 0.90-0.92 gram/cubic centimetre plastics, thermoplasticity EPDM dynamic perduren 23 weight portions.
10, density is 80 weight portions at the PE of 0.90-0.92 gram/cubic centimetre plastics, the fire retardant that the flame-proof environmental protection particle of U.S.'s mark fireproof powder of thermoplasticity EPDM dynamic perduren 21 weight portions and 0.4 weight portion (Hunan shakes and contains the production of polyurethane material Co., Ltd) constitutes.
11, density is 90 weight portions at the PE of 0.90-0.92 gram/cubic centimetre plastics, the Firemaster CA 117 of thermoplasticity EPDM dynamic perduren 15 weight portions and 0.2 weight portion.
12, density is 70 weight portions at the PE of 0.90-0.92 gram/cubic centimetre plastics, the fire retardant BS5852 of thermoplasticity EPDM dynamic perduren 25 weight portions and 0.3 weight portion.
What fire retardant adopted in the above-described embodiments is the agent of polyurethanes fire retardant.
In the material of above-mentioned environmental protection wall fitting wallpaper material coat constituted, thermoplasticity EPDM dynamic perduren was a kind of macromolecular elastomer material, and its English name is Thermal Plastic Vulcanizate, was called for short TPV.
In the material of above-mentioned environmental protection wall fitting wallpaper material coat constitutes, select the PE plastics of its density for use, i.e. the moderate PE plastics of molecular weight in 0.88-0.92 gram/cubic centimetre scope.Because the molecular weight of the PE plastics of being selected for use is big, density is less; Adding an amount of TPV macromolecular elastomer material; Can make the soft more and high resilience of wall fitting wallpaper material of prepared one-tenth, and solve the adaptability of the direct colour print of wall fitting wallpaper material.If select the PE plastics of density big (also being that molecular weight is less) for use,, also be not enough to make formed coat deliquescing although also add TPV macromolecular elastomer material; The PE plastics of density big (also being that molecular weight is less) heat melt form institute to form colloidal liquid after on stream film to the body paper paper time, can make formed wallpaper material take place to roll up to stick up and be difficult to use.
