preparation example Construction

[0024] A method for preparing low-emission TVOC foamed polypropylene products, comprising: mixing polypropylene resin and fibers, then mixing with porous absorbent materials and coupling cross-chaining agents to form a mixture, and heating the mixture at a temperature of 160-210°C Foaming under the action of nitrogen after extrusion.

[0025] The polypropylene resin and fiber do not react when mixed, and the polypropylene resin and fiber can be fully mixed evenly, which is conducive to the uniform distribution of the fiber in the foamed polypropylene product, and can make the foamed cells more uniform. After the polypropylene resin is mixed with the fiber, it is mixed with the porous absorbent material and the coupling cross-linking agent, and then melted into a melt at a temperature of 160-210 ° C, extruded after the cross-linking reaction, and then under the action of nitrogen Foaming. In an embodiment of the present invention, the purity of nitrogen is greater than or equa...

Abstract

The invention discloses a low-emission TVOC foamed polypropylene product and a preparation method thereof and relates to the field of polypropylene products. The low-emission TVOC foamed polypropylene product is mainly prepared by taking nitrogen as foaming gas to foam. The raw materials comprises the following components in parts by weight: 70-80 parts of polypropylene resin, 0.5-2 parts of a deodorant, 1-10 parts of fibers, 5-15 parts of a coupling interlinking agent and 1-10 parts of a porous adsorption material. The foamed polypropylene overcomes the defect of high release amount of TVOC. The preparation method of the low-emission TVOC foamed polypropylene product comprises the following steps of: mixing the polypropylene resin with fibers; then mixing the mixture with the porous adsorption material and the coupling interlinking agent to form a mixture; and extruding the mixture to foam under the action of nitrogen. By using nitrogen to foam the polypropylene resin, in addition to the action of adsorption, coupling cross-linking reaction and fibers, purposes of reducing the TVOC content of the foamed polypropylene and improving the odor grade are achieved.

Description

technical field [0001] The invention relates to the field of polypropylene products, and in particular to a low-emission TVOC foamed polypropylene product and a preparation method thereof. Background technique [0002] At present, my country's automobiles and indoor environmental pollution are relatively serious. The TVOC (Total Volatile Organic Compounds, the total of volatile organic compounds) in the car and indoors mainly comes from carpets, plastic parts, seats and other plastic parts and glue used in decoration. Wait. The organic solvents, additives, additives and other volatile components contained in the plastic and rubber parts, fabrics, paint coatings, thermal insulation materials, adhesives and other materials used in them are released into the car and indoor environment, seriously affecting the car and indoor environment. Environment, causing car, indoor air pollution. Toxic gases contained in decorative materials mainly include benzene, formaldehyde, acetone, x...
