Embodiment 1

[0019] First adopt emulsion method to synthesize acrylate emulsion: concrete steps are (1) dissolving of emulsion, under normal temperature in reactor, nonylphenol polyoxyethylene ether, sodium dodecylbenzenesulfonate are dissolved in deionized water, Stir continuously to form an emulsifier solution; (2) Add butyl acrylate, butyl methacrylate, and methacrylic acid monomers to the emulsifier solution, stir quickly and evenly, then start to reduce the stirring speed, and gradually heat up to 80°C, After the solution reacts with blue light, add ammonium persulfate aqueous solution dropwise. After the ammonium persulfate aqueous solution is added dropwise, the temperature rises to 85°C, and the reaction ends after 2 hours of heat preservation; (3) cool the reaction product to 30°C, add ammonia water to adjust When the pH value reaches neutral, the acrylic emulsion can be obtained by discharging.

Abstract

The invention relates to a preparation method of a car carpet material with a self-adhesive foam adhesive and belongs to the technical field of high polymer materials. The preparation method includes: using acrylate as the main raw material, subjecting the acrylate to polymer blending modification, adding a physical foaming agent and modified nano cellulose to obtain a self-adhesive foam carpet material back adhesive, coating a nonwoven-fiber carpet or a cotton-spun carpet material with the self-adhesive foam carpet material back adhesive, and drying to obtain a self-adhesive carpet product. The carpet material having certain self-adhesive performance is free of low-molecular volatile matter, environmentally friendly, nontoxic, low in density, capable of being tightly adhered to the inner bottom surface of a car, capable of avoiding shifting during use and convenient to use.

Description

technical field [0001] The invention relates to a method for preparing an automobile carpet material with self-adhesive foaming glue, and belongs to the technical field of polymer materials. Background technique [0002] With the rapid development of my country's automobile industry, the amount of carpet materials in automobile interior parts is also increasing. At present, the car carpet materials mainly include PVC carpet, PET needle-punched carpet, EVA composite carpet, PA tufted carpet and so on. Among them, the PVC material carpet does not meet the air quality standards in the car due to the volatilization of toxic and harmful substances such as plasticizers at high temperatures. At present, the carpets sold on the market will shift during use, especially the shift of the carpet under the driver's feet, which will cause potential safety hazards in driving. At present, the weight reduction of automobile materials is an important development direction. As one of the int...
