Abstract

The invention discloses an economical polystyrene heat-preservation extruded board. The economical polystyrene heat-preservation extruded board is prepared from the following components in parts by weight: 400 to 600 parts of polystyrene particles, 10 to 15 parts of butyl peroxybenzoate, 8 to 12 parts of sodium dodecylbenzene sulfonate, 10 to 15 parts of benzoyl peroxide, 0.5 to 1.2 parts of alkenyl succinate, 0.8 to 1.2 parts of zinc dialkyl dithiophosphate, 5 to 10 parts of a nucleating agent, 4 to 8 parts of color master batch, 0.8 to 12 parts of a mildew-proof agent and 3 to 5 parts of a foaming agent, wherein the polystyrene particles are formed by mixing new polystyrene materials, polystyrene recycled materials and polystyrene waste materials and the mixing ratio is 1 to 2 to 2. The new polystyrene materials, the recycled materials and the waste materials are mixed to form a main material, so that the production cost of enterprises is greatly reduced and the economic benefits are improved.

Description

technical field

[0001] The invention relates to an extruded plastic board, in particular to an economical thermal insulation extruded board. Background technique

[0002] Existing external wall insulation materials on the market mainly use modified benzene board, polyurethane board and extruded board. Among them, benzene board is the cheapest, and its insulation effect is average, and it will absorb water and deform. After the insulation layer is completed, other waterproof measures are required. . Polyurethane is the best performance among existing insulation materials. Polyurethane is used as insulation material in refrigerators and cold storage. The thermal conductivity is far lower than that of benzene board and extruded board. Basically, half the thickness of polyurethane insulation layer can reach The insulation effect of the original thickness of benzene board and extruded board, but the price is much higher than that of benzene board and extruded board. Compared wi...
