Problems solved by technology

At present, the shrinkage rate of the commonly used composite material mat reaches 5% to 8%, so when the roof temperature changes rapidly, the shrinkage of the composite material mat will cause it to be broken by structures such as iron nails used for fixing, resulting in functional defects
And the existing composite material mat can stick the anti-slip film made of EVA and PE material with polyurethane on the surface for increasing its friction with the roof. The solvent evaporates, causing certain pollution

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the examples, but not as a basis for limiting the present invention.

[0025] A polymer composite cushion, including PP non-woven fabric 1, a coating layer 2 blended with PP material and PE material, and PP woven fabric 3, which are sequentially combined, and a layer is arranged on the PP woven fabric by hot oil spraying Anti-skid layer4. The anti-slip layer 4 includes 50 parts of PE, 35 parts of PP / PE / EVA blend and 15 parts of PIB / PE blend in parts by mass. The 35 parts of PP / PE / EVA blended materials include, by mass parts, 15 parts of PP, 5 parts of PE and 15 parts of EVA. The 15 parts of PIB / PE blended material, by mass parts, include 10 parts of PIB, 4 parts of PE and 1 part of dispersant.

[0026] A preparation method of a polymer composite cushion, comprising the steps of:

[0027] ① Draw and weave the PP material to form PP woven fabric;

[0028] ②Heat setting of PP woven fabric;

[00...

Abstract

The invention discloses a macromolecular composite cushion layer and a preparation method of the macromolecular composite cushion layer, the macromolecular composite cushion layer comprises a PP (polypropylene) non-woven fabrics layer (1), a coating layer (2) mixed by PP materials and PE (polyethylene) materials, and a PP woven cloth layer which are compounded in sequence, wherein an anti-skidding layer (4) is arranged on the PP woven cloth layer by the hot spray oil method. According to the macromolecular composite cushion layer, the composite cushion layer can have enough friction by a more environment-friendly method, the contractibility rate of the composite cushion layer is reduced, and the function is more stable.

Description

technical field [0001] The invention relates to a polymer composite cushion and a preparation method thereof, in particular to a polymer composite cushion for laying on the roof of a building and a preparation method thereof. Background technique [0002] On the roof of a building, especially a wooden structure roof, in order to achieve the purposes of waterproofing and heat insulation, it is usually necessary to carry out construction reconstruction on the roof. The traditional method is to lay asphalt and reflective materials on the roof, but asphalt not only cannot meet the environmental protection requirements, but also the construction is more complicated. Therefore, more and more people at home and abroad are using composite material mats that are ready to be used for roofing. At present, the shrinkage rate of the commonly used composite material mat reaches 5% to 8%, so when the roof temperature changes rapidly, the shrinkage of the composite material mat will cause ...
