Abstract
The invention discloses an anti-shrinkage method of a polymer composite cushion layer. The anti-shrinkage method comprises the following steps of: performing heat setting treatment on PP (polypropylene) woven fabric in the polymer composite cushion layer, and further compounding with other material layers. According to the anti-shrinkage method disclosed by the invention, the shrinkage rate of the polymer composite cushion layer can be reduced to be lower than 1.5%, so that the stability is very high, and the functional problems, such as fracture and the like, caused by height shrinkage, can be avoided under the situation that the temperature changes rapidly.
Description
Technical field
The present invention relates to a kind of anti-contraction method of macromolecule composite cushion, particularly a kind of anti-contraction method that is used to be laid on the macromolecule composite cushion on building roof.
Background technology
Roof on the roof of building constructions, particularly timber structure, for reaching waterproof, purpose such as heat insulation, usually need be to the roof transformation of constructing.And traditional way is at roofing pitch, reflectorized material, but pitch not only can't satisfy environmental requirement, and the also more complicated of constructing.Therefore, adopt more and more both at home and abroad and paste promptly promptly that the composite wood backing strap of usefulness carries out roofing.At present, the shrinkage factor of common employed composite wood backing strap reaches 5% to 8%, so when the roof temperature sharply changed, the contraction of composite wood backing strap can make the structures such as iron nail of its usefulness that is fixed burst, and causes producing functional defect.
Summary of the invention
The objective of the invention is: the anti-contraction method that a kind of macromolecule composite cushion is provided.It can reduce the shrinkage factor of composite cushion, makes its function more stable.
The object of the invention can be realized through following technical proposal: a kind of anti-contraction method of macromolecule composite cushion is characterized in that: after the PP woven cloth in the macromolecule composite cushion is carried out the thermal finalization processing, carry out itself and other material layer compound again.PP is Woven cloth compounded in the macromolecule composite cushion.
In the anti-contraction method of above-mentioned macromolecule composite cushion, the method that said thermal finalization is handled is:
A, with the PP woven cloth as in the baking oven, and strut pull tight;
The vitrification point of b, heated oven to PP material, and be incubated 5 minutes;
C, the PP woven cloth is shifted out baking oven cool off rapidly, and rolling.
Among the preparation method of aforesaid macromolecule composite cushion, the vitrification point among the said step b is 80 ℃～110 ℃.
Compared with prior art; The present invention handles through the typing to the PP woven cloth; Macromolecule composite cushion shrinkage factor of the present invention is reduced to below 1.5%, and therefore stability is high, under temperature situation jumpy, also functional issues such as high shrinkage causes breaking can not occur.
Description of drawings
Fig. 1 is the structural representation of macromolecule composite cushion among the embodiment.
Mark in the accompanying drawing: the 1-PP nonwoven, 2-is coated with rete, 3-PP woven cloth, 4-skid resistant course.
The specific embodiment
Below in conjunction with embodiment the present invention is further described, but not as the foundation to the present invention's restriction.
The macromolecule composite cushion, what comprise the PP nonwoven 1, PP material and the blend of PE material that are combined with each other successively is coated with rete 2 and PP woven cloth 3, also is provided with one deck skid resistant course 4 on the PP woven cloth.A kind of anti-contraction method of macromolecule composite cushion is characterized in that: after the PP woven cloth in the macromolecule composite cushion was carried out the thermal finalization processing, itself and other material layer carried out compound again.PP is Woven cloth compounded in the macromolecule composite cushion.
In the anti-contraction method of above-mentioned macromolecule composite cushion, the method that said thermal finalization is handled is:
A, with the PP woven cloth as in the baking oven, and strut pull tight;
The vitrification point of b, heated oven to PP material, and be incubated 5 minutes;
C, the PP woven cloth is shifted out baking oven cool off rapidly, and rolling.
Among the preparation method of aforesaid macromolecule composite cushion, the vitrification point among the said step b is 80 ℃～110 ℃.
