Abstract
The invention relates to a filler for a thermal insulation building external wall panel, which consists of the following raw materials in percentage by weight: 48-52% of cement; 46-51% of polyphenyl granules or vitrified micro bubbles; 0.1 to 0.4 percent of aluminum sulfate; 0.06-0.069% of ferric chloride; 0.2 to 0.54 percent of polyvinyl alcohol; 0.2-0.54% of starch; 0.2 to 0.54 percent of sugar calcium. The invention has the beneficial effects that: the cement content is reduced to about 50 percent, the lightweight aggregate is increased to about 50 percent, and the lightweight heat-insulating external wall panel is formed by pouring after adding the cementing material and stirring, so that the heat-insulating performance of the product reaches four energy-saving requirements of the state, and the lightweight heat-insulating external wall panel has the following advantages: high strength, light volume weight, good heat preservation, fire prevention, sound insulation, crack resistance and frost resistance, and the product strength can reach 3.5 MPa.
Description
Technical Field
The invention relates to a filler for a thermal insulation building external wall panel, which is applied to the field of building materials.
Background
The filler of the heat-insulating building external wall panel in the prior art comprises heat-insulating materials such as cement, sand, polyphenyl granules, ceramsite, vitrified micro bubbles and the like, the cement and sand have larger participation amount, and the lightweight aggregate has less participation amount, so that the heat-insulating effect can not meet the national requirements for four energy conservation, and the produced heat-insulating building external wall panel has the defects of low strength, insufficient hanging force, high water absorption rate and the like. Especially when the lightweight aggregate polyphenyl particles and the perlite are used, the participation amount of the cement is very large and reaches more than 80 percent of the proportion amount, so that the heat preservation effect of the wall body can not meet the requirement of the national standard at all, and due to the loose property of the lightweight aggregate, even if the participation amount of the cement reaches 80 percent, the compressive strength, the hanging force, the water absorption rate and the like of the produced wallboard can hardly reach the national standard.
Disclosure of Invention
In view of the defects in the prior art, the invention relates to a filler for an external wall panel of a heat-insulating building, which has high strength, light volume weight, good heat-insulating, fireproof, sound-insulating, anti-cracking and anti-freezing properties.
In order to achieve the purpose, the invention adopts the technical scheme that: the utility model provides a filler for heat preservation building side fascia which characterized in that: the composite material consists of the following raw materials in percentage by weight:
48-52% of cement;
46-51% of polyphenyl granules or vitrified micro bubbles;
0.1 to 0.4 percent of aluminum sulfate;
0.06-0.069% of ferric chloride;
0.2 to 0.54 percent of polyvinyl alcohol;
0.2-0.54% of starch;
0.2 to 0.54 percent of sugar calcium.
The invention has the beneficial effects that: the application is used for the filler of the heat-insulating building external wall panel, the cement participation amount is reduced to about 50%, the lightweight aggregate is increased to about 50%, the lightweight heat-insulating external wall panel formed by pouring after the cementing material is added and stirred, the heat-insulating performance of the product reaches four energy-saving requirements of the state, and the filler has the following advantages: high strength, light volume weight, good heat preservation, fire prevention, sound insulation, crack resistance and frost resistance, the product strength can reach 3.5MPa, the hanging force and the waterproof performance are greatly improved, and the whole cost is 20 percent lower than that of the prior art.
