High-temperature-resistant constructable high-performance LASD

Abstract

The invention discloses high-temperature-resistant constructable high-performance LASD including, by weight, 250-500 parts of acrylic acid emulsion, 5-10 parts of a dispersant, 5-10 parts of a defoamer, 5-10 parts of a leveling agent, 3-8 parts of a preservative, 3-10 parts of a thickener, 250-400 parts of heavy calcium, 150-250 parts of mica, and 150-250 parts of needle-like silica powder. The LASD is low in VOC emission quantity, is environment-friendly and low-odor, is convenient to construct and use by using a mechanical spray gun, is free of manufacturing and shaping with a specific moldin advance, and is lower in cost. The LASD also solves the problems that a conventional asphalt sound-insulation and vibration-absorptive material is brittle in winter and sticky in summer.

Description

technical field [0001] The invention relates to the technical field of automobile sound insulation and shock absorption, in particular to a high-performance LASD with high temperature resistance and easy construction. Background technique [0002] At present, asphalt materials are mainly used for sound insulation and shock absorption in automobiles. This material has disadvantages such as high VOC emissions, unfriendly to the environment, strong smell, brittle in winter, sticky in summer, and inconvenient construction. [0003] The invention patent with the application number CN201710699951.6 provides a sound insulation material for automobiles, which uses ethylene-vinyl acetate copolymer and EPDM rubber, and uses tetraacicular zinc oxide whiskers as fillers, but there is still a need Customizing different molds for different models to produce sound-insulating components that adapt to the shape has the problems of high cost of sound-insulating construction and inconvenient c...
