Description

Sound-proof waterproof PVC woven wall cloth

Technical Field

The utility model relates to a PVC wall paper technical field, concretely relates to waterproof PVC of giving sound insulation weaves wall paper.

Background

Teslin is a special textile produced by a shuttleless loom, and adopts composite yarns with a special cladding structure, namely PVC/PET sheath-core yarns. The core body is made of high-strength polyester industrial filaments, and the skin layer is made of an anti-aging and anti-ultraviolet radiation polyvinyl chloride (PVC) material. Stretching and covering the polyester filament yarn, and drawing and cooling to form the composite yarn with smooth surface, water resistance, oil resistance, no toxicity and cool feeling. Warp yarns are made into a driving shaft through an intelligent warping machine, sizing is not needed, the warp yarns are directly woven on a winding rapier loom to form a net, and then the net is finished into a final product. The color-changing paint has the advantages of bright color, fastness, high tensile force, water resistance, oil resistance, ultraviolet resistance, aging resistance, wear resistance, rot resistance, chemical resistance, no toxicity, smooth and cool surface, excellent air permeability, long service life and the like.

The textilene woven wall cloth can show the texture and the texture of products, but the current textilene made wall cloth has less reports.

Disclosure of Invention

Fig. 1 is a partial cross-sectional view of the present invention;

the reference signs are: 1-a substrate layer, 2-a first bonding layer, 3-an aerogel layer, 4-a second bonding layer, 5-a woven layer and 6-a waterproof breathable layer.

Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and the accompanying fig. 1, which are not intended to limit the present invention.

The utility model provides a waterproof PVC that gives sound insulation weaves wall paper, includes substrate layer 1, first tie coat 2, aerogel layer 3, second tie coat 4, weaving layer 5 and waterproof ventilative layer 6 of compounding in proper order from bottom to top, weaving layer 5 comprises warp and weft that interweaves, warp and weft are PVC/PET skin core type yarn.

The aerogel layer 3 is a porous spongy structure solid matter form, has a large number of nano micro-pores and extremely low density, is an ideal heat-insulating and sound-insulating material, and can endow the practical wall cloth with certain sound-insulating performance; because the wall cloth is weaved for the textilene yarn, so there is the air easily between the yarn, and steam can see through weaving layer 5 invasion and attack wall cloth inlayer or wall, consequently through the waterproof ventilative layer 6 of the compound one deck of upper surface at weaving layer 5, can hinder the passing through of water, gives the wall cloth certain waterproof performance.

Wherein, substrate layer 1 is PVC substrate layer 1, the thickness of PVC substrate layer 1 is 1.5 mm. PVC has better smoothness as a base material, and is favorable for bonding with a wall surface. Considering aspects such as weight, cost, performance and the like of the PVC substrate layer 1, in other alternative embodiments, the thickness of the PVC substrate layer 1 may be 0.5mm, 1mm, 1.2mm, 1.6mm, 1.7mm, 2.0mm and the like.
