Embodiment 1

[0018] Add 1 part of foaming agent, 0.6 part of nucleating agent, 0.1 part of lubricant, 7 parts of modifier and 8 parts of flame retardant to 100 parts of polystyrene resin, stir well, pre-foam by heating, and then Extruded into a mould.

[0019] Wherein, 0.3 part of citric acid and 0.3 part of sodium bicarbonate are included in the described nucleating agent.

[0020] The lubricant is calcium stearate, which can improve the processability of the polystyrene resin during extrusion molding.

[0021] The resulting new type of exterior wall thermal insulation material for buildings has excellent thermal insulation performance, its strength has been increased by more than 30%, its weather resistance has been enhanced by 1.5 times, and its service life can reach more than 100 years.

Embodiment 2

[0023] Add 0.8 parts of foaming agent, 0.8 parts of nucleating agent, 0.2 parts of lubricant, 6 parts of modifier and 6 parts of flame retardant to 100 parts of polystyrene resin, stir well, pre-foam by heating, and then Extruded into a mould.

[0024] Wherein, 0.4 part of citric acid and 0.4 part of sodium bicarbonate are included in the nucleating agent.

[0025] The lubricant comprises 0.1 part of silicone oil and 0.1 part of liquid paraffin, which can improve the processability of polystyrene resin during extrusion molding.

[0026] The resulting new type of exterior wall thermal insulation material for buildings has excellent thermal insulation performance, its strength has been increased by more than 30%, its weather resistance has been enhanced by 1.5 times, and its service life can reach more than 100 years.

[0027] The invention discloses a new type of thermal insulation material for external walls of buildings, which uses polystyrene resin as a raw material, and th...

Abstract

The invention discloses a novel external wall insulation material for a building. Materials are heated for pre-foaming after the materials are mixed uniformly, and then the materials are subjected to extrusion molding in a mould. The materials comprises, by weight, 100 parts of polystyrene resin, 0.7-1.2 parts of a foaming agent, 0.4-0.8 part of a nucleating agent, 0.1-0.3 part of lubricant and 10-15 parts of other auxiliary agents. The novel external wall insulation material for the building is good in strength and has functions of heat insulation, weather-proofing, indoor temperature stability maintenance, moisture-proofing, external wall frosting resistance and the like, so that the service life of the building is prolonged.

Description

technical field [0001] The invention relates to the field of building decoration materials, in particular to a new type of thermal insulation material for external walls used in buildings. Background technique [0002] With the rapid development of the construction industry and the promotion and development of building energy conservation, people pay more and more attention to thermal insulation materials and products. [0003] At present, the most commonly used external wall insulation material is polystyrene plastic foam board, and its main material is polystyrene resin. Because ordinary polystyrene resin is non-toxic, odorless, colorless, and glass-like, its products have extremely High transparency, light transmittance can reach more than 90%, good electrical insulation performance, easy coloring, good processing fluidity, good rigidity and good chemical corrosion resistance, etc., so it is favored by people. However, it is brittle, has low impact strength, is prone to ...
