Problems solved by technology

[0003] However, the VOC of the oily system is too high. In the process of production, transportation, and use, environmental protection and safety supervision requirements are becoming more and more stringent. It is becoming more and more difficult for related companies to meet the qualification requirements, resulting in high product costs. Environmental requirements and industrial hygiene requirements are becoming more and more stringent, and customers also hope to use environmentally friendly products

Abstract

The invention discloses water-based high-solid-content damping rubber and a preparation method thereof, and belongs to the technical field of new materials. The water-based high-solid-content damping rubber comprises styrene-acrylic emulsion, pure acrylic emulsion, functional powder and functional auxiliaries, the functional powder comprises fibers, and the fibers are one or more of mineral fibers, modified synthetic fibers, plant fibers and modified plant fibers; and the mass percentages of the components are respectively 20-40% of the styrene-acrylic emulsion, 5-20% of the pure acrylic emulsion, 52-65% of the functional powder and 3-10% of the functional auxiliaries. The method comprises the following steps: adding the components into a dispersion cylinder, performing stirring, starting high-speed dispersion, performing uniform mixing, adjusting the pH value, and detecting a product to be qualified to obtain a finished product. The damping rubber obtained by the invention is high in solid content and low in VOC (volatile organic compounds), not only can meet the environmental protection requirement, but also has the effects of quick drying, no blistering and no cracking.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a water-based high-solid damping and shock-absorbing glue and a preparation method thereof. Background technique [0002] Damping and shock absorbing glue is generally used in the fields of motor vehicle chassis protection, battery protection, sound insulation and noise reduction in metal spaces, gap filling and sealing of various substrates, and prevention of positioning bolts and nuts from falling off. Oil-based or PVC plastisol-based damping and shock-absorbing adhesives have been widely used in automobiles and other fields. [0003] However, the VOC of the oily system is too high. In the process of production, transportation, and use, environmental protection and safety supervision requirements are becoming more and more stringent. It is becoming more and more difficult for related companies to meet the qualification requirements, resulting in high product costs. Envir...
