Polymer foam material and preparation method thereof

Abstract

The invention discloses a polymer foam material and a preparation method thereof. The polymer foam material is composed of the following components in parts by mass: 25-35 parts of melamine resin, 4-6 parts of zinc oxide, 20-30 parts of rubber, 3-5 parts of zinc oxide, 4-6 parts of stearic acid, 5-7 parts of antioxidant, 6-8 parts of sulfur, 4-6 parts of polystyrene beads, 3-5 parts of an accelerator, 10-12 parts of stearic acid, 4-6 parts of melamine formaldehyde resin, 1-3 parts of a heat curing crosslinking agent and 1-2 parts of a crosslinking agent. The polymer foam material provided by the invention is simple in production process and stable in operation.

Description

technical field [0001] The invention relates to the field of artificial materials, in particular to a polymer foam material and a preparation method thereof. Background technique [0002] An existing Chinese invention patent with the application number 200910176780.4 titled "Copolymer Foam and Its Preparation Method" discloses a formula and a preparation method. The raw materials of the foam are: methacrylic acid 32-72wt%, acrylonitrile 68- 28wt%, initiator 0.08~0.50wt%, blowing agent 1.0~9.0wt%, initiator is selected from peroxidized organic acid ester; preparation steps are as follows: under water temperature 35~65 ℃, polymerize 22~75h; Will obtain The foamable copolymer sheet is freely foamed in the strong circulating hot air at 180-220°C to prepare the copolymer foam; the obtained copolymer foam is heat-treated in the hot air at 120-180°C for 4~ 12h. The copolymer foam uses acrylonitrile instead of expensive methacrylonitrile, and uses organic peroxide instead of azo c...
