Problems solved by technology

Although polystyrene board has a good thermal insulation effect in use as a rubber and plastic insulation material, due to the characteristics of the board, when the polystyrene board is connected to the main body during construction, it is mainly point-fixed and surface-fixed as a supplement. Necessary splicing and bonding are not suitable for thermal insulation of buildings with complex shapes. The construction process is complicated and the overall cost is high.
At the same time, because the hydrophobicity of polystyrene board is not suitable for conventional hydrophilic materials, it is difficult to guarantee the quality of subsequent construction other than the sur

Abstract

The invention discloses a preparation method for an antibacterial type rubber-plastic foaming thermal insulation material. The preparation method comprises the following steps: banburying chloroprene rubber, acrylonitrile-butadiene rubber and an ethylene-propylene methylene copolymer to a molten state at a temperature of 60-85 DEG C; adding phenolic resin, 4-aminophenethylalcohol, stearic acid and tributyl citrate, and mixing for 10-20 minutes at a temperature of 90-110 DEG C; when the temperature is reduced to 60-80 DEG C, adding carbohydrazide, calcium carbonate and normal hexane, and increasing the temperature to 100-120 DEG C; after reaching the temperature, continuously adding salicylanilide and active carbon supported with silver nitrate, continuously increasing the temperature to 160-200 DEG C, stirring and reacting for 20-40 minutes after keeping for 5-8 minutes, and cooling, cutting and drying, thereby obtaining the antibacterial type rubber-plastic foaming thermal insulation material. While antibacterial performances are improved, the heat conduction coefficient is further reduced, so that thermal insulation is better; and comprehensive properties of the material are improved through cooperation of rubber and plastic.

Description

technical field [0001] The invention belongs to the field of foam insulation materials, in particular to an antibacterial rubber-plastic foam insulation material and a preparation method thereof. Background technique [0002] Rubber and plastic insulation materials are elastic closed-cell elastic materials, which can be widely used in construction, chemical industry, textile, metallurgy, communication, vehicles, electrical appliances and other industries and parts of various cold and hot medium pipes and containers, which can reduce cold loss and heat loss. The effect of loss, so it is a high-quality cross-century new generation of thermal insulation material. As early as the 1970s and 1980s, foreign developed countries had precedents in applying rubber and plastic insulation materials to the construction field, especially in building energy conservation, which has been widely valued and made great achievements. The building energy consumption in these countries For example...
