Abstract

The invention discloses a production process of a composite cored EPS foam plastic panel. The composite cored EPS foam plastic panel comprises an upper epoxy resin board, wherein an EPS foam plastic board is arranged at the bottom of the upper epoxy resin board, and a lower epoxy resin board is arranged at the bottom of the EPS foam plastic board; and the EPS foam plastic board contains the following raw maters in parts by weight: 40-50 parts of polystyrene particles, 5-10 parts of an organic silicon emulsion waterproof agent, 5-10 parts of an adhesive, 4-8 parts of pentane, 4-8 parts of a flame retardant, 3-5 parts of methyl hexahydrophthalic anhydride, 3-5 parts of hydrogen-containing silicone oil and 3-5 parts of benzotriazole. By utilizing decabromodiphenyl ether as the flame retardant, the composite cored EPS foam plastic panel has good heat resistance, is healthy to a human body, has no risk and is environmentally friendly; hydrogen-containing silicone oil is added to be matchedwith the double-layer epoxy resin board and methyl hexahydrophthalic anhydride during the curing and stirring, so that the structural strength of the machined and formed EPS foam plastic panel is improved, and the EPS foam plastic panel dost not attract dust in a working environment with a high dust content, and the aesthetic degree of the EPS foam plastic panel is increased.

Description

technical field [0001] The invention relates to the technical field of plate production, in particular to a production process of composite cored EPS foam plastic plate. Background technique [0002] EPS board (expandable polystyrene board) has the advantages of light weight, low price, low thermal conductivity, small water absorption, good electrical insulation performance, sound insulation, shockproof, moisture-proof, and simple molding process, so it is widely used in construction, Thermal insulation, sound insulation, and shock-resistant materials for ships, automobiles, trains, refrigerators, and freezers. The sandwich panel has beautiful appearance, bright color and good overall effect. It integrates load-bearing, heat preservation, fire prevention and waterproof, and does not require secondary decoration. It is a widely used shock-absorbing material. [0003] The existing EPS foam plastic sheet has single structure, poor heat resistance, low structural strength, high...
