Problems solved by technology

At present, the adhesives used in automotive interiors usually contain a large amount of harmful substances such as formaldehyde, benzene, and xylene due to the use of non-environmentally friendly organic solvents. At the same time, the interior space of the car is limited and is usually in a sealed state, which is harmful to human health. pose a huge threat
Therefore, the current adhesives for automotive interiors still have problems such as insufficient environmental performance and poor bonding performance, which are far behind the market's demand for high-quality automotive interior adhesives.

Abstract

The invention discloses an adhesive for automobile interior decoration and a preparation method of the adhesive. The prepared adhesive for automobile interior decoration has relatively high peeling strength, good anti-aging performance and excellent anti-aging performance, is environmentally friendly and pollution free, and is safe and the sustainable. The anti-aging performance of the adhesive isenhanced through the synergistic effect of hokutolite and agate, so that after the adhesive is treated in water at a temperature of 80 DEG C for 400 hours, the adhesive tensile strength retention rate is about 98%, and the anti-aging performance is good. A silicone-acrylate emulsion is used for treating the hokutolite and the agate, so that the dispersity of the hokutolite and the agate in an adhesive substrate can be enhanced, and peeling strength and bonding performance are improved. Through the addition of polypropylene fibers, the forming of an interpenetrating three-dimensional network is facilitated, and the peeling strength of the adhesive is greatly enhanced.

Description

technical field [0001] The invention belongs to the technical field of adhesives, in particular to an adhesive for automotive interior decoration and a preparation method thereof. Background technique [0002] With the development of the automobile industry, the interior of the car is becoming more and more luxurious, so the amount of glue used for bonding the interior of the car is also increasing. At present, the adhesives used in automotive interiors usually contain a large amount of harmful substances such as formaldehyde, benzene, and xylene due to the use of non-environmentally friendly organic solvents. At the same time, the interior space of the car is limited and is usually in a sealed state, which is harmful to human health. pose a huge threat. Therefore, the current automotive interior adhesives still have problems such as insufficient environmental performance and poor bonding performance, which are far behind the market's demand for high-quality automotive inte...
