Macromolecular composite cushion layer and preparation method of macromolecular composite cushion layer

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 ...
