Anti-broken hot melt adhesive membrane used for automobile decoration and preparation method of anti-broken hot melt adhesive membrane

Abstract

The invention discloses an anti-broken hot melt adhesive membrane used for automobile decoration and a preparation method of the anti-broken hot melt adhesive membrane. The anti-broken hot melt adhesive membrane comprises a PVB base adhesive, a TPU adhesive layer is stuck to the outer wall on one side of the PVB base adhesive, a photochromic layer is stuck to the outer wall on the side, away fromthe PVB base adhesive, of the TPU adhesive layer, a nylon mesh cloth layer is stuck to the outer wall on the side, away from the TPU adhesive layer, of the photochromic layer, and a membrane surface layer is stuck to the outer wall on the side, away from the photochromic layer, of the nylon mesh cloth layer. The preparation method comprises the following steps of preparation of raw materials, wherein a PVB adhesive solution, an EVA adhesive solution and a TPU adhesive solution which are needed during production are mixed and stirred respectively, and then sampled and inspected respectively; preparation of coating machines, wherein the three coating machines are prepared, and adhesive storage cylinders and coating heads of the three coating machines are cleaned. By means of the anti-brokenhot melt adhesive membrane, improvement of the wear-resistant performance of the surface of the hot melt adhesive membrane is facilitated, by cooperatively arranging the nylon mesh cloth layer, improved of the adhesion effect of the surface layer of the membrane can be facilitated, the box stretching performance of the hot melt adhesive membrane is improved, and improvement of the elasticity of the hot melt adhesive membrane is facilitated.

Description

technical field [0001] The invention relates to the technical field of hot-melt adhesive film for automobile decoration, in particular to a water-breaking-proof hot-melt adhesive film for automobile decoration and a preparation method thereof. Background technique [0002] Car body film is attached to the surface of the car paint by polymer materials to protect the original paint and decorate the car body. It can be easily removed at any time. It is in sharp contrast to the chemical changes of the paint surface such as traditional sealing glaze, coating and spray painting. Automobile body film is a high-performance initial low-viscosity polyvinyl chloride film specially designed for automobile body film. It has the properties of fully fitting the paint surface of the car body and the surface of various substrates in the interior, and is more convenient for construction, flexible and durable. , Anti-chemical corrosion, stronger opacity and many other advantages. It can effec...

AI Technical Summary

Problems solved by technology

It can effectively ensure accurate, seamless, and bubble-free coating when facing the curved body surface during construction, and will not cause damage to the car paint. On the contrary, it will fully protect the original paint of the vehicle. Hot melt adhesive film is a common Automobile film, the existing hot-melt adhesive film for automobile decoration is easy to be damaged, and its tensile resistance and deformation resistance are general. Therefore, a kind of anti-water-breaking hot-melt adhesive film for automobile decoration and its preparation method are now proposed.
