Problems solved by technology

However, this form of operation has several obvious disadvantages: 1. The resource consumption is huge, and the precision is not high, and the waste is huge; 2. The raw materials are transported to the project site, and all the construction operations are completed on site, and the dust pollution is obvious, which is not conducive to environmental protection; 3. A large amount of labor is required for on-site operations, the labor cost is huge, and the working environment is harsh, and various types of work-related injuries are prone to occur; 4. The construction period is long, and various social resources are occupied, etc.

Embodiment 1

[0032] PLHC light raw material slurry mixing and stirring step; filling the PLHC light raw material slurry into the entire specified mold, and then drying and molding with the mold under specified conditions, and then reacting at a higher temperature to form it; adding PLHC Fill the entire mold with the light raw material slurry, and then carry out the following treatment together with the mold, standing at room temperature for 3 hours, and then reacting at 45°C for 24 hours; after the demoulding step, the product is obtained; after drying, and then in the product Paint the exterior with acrylic paint.

[0033] The overall waterproof performance of the product obtained in Example 1 is greatly improved, and the surface strength is increased.

Embodiment 2

[0035] PLHC light raw material slurry mixing step; 80 parts of cement, 5 parts of water glass, and 40 parts of water are prepared in proportion to the quick-setting slurry, and the quick-setting slurry is evenly coated on the inner wall of the mold. The interior of the mold is evenly coated with a high-density quick-setting raw material slurry to form a quick-setting layer; add PLHC light raw material slurry to fill the entire mold, and then carry out the following treatment together with the mold, and carry out static molding at room temperature for 3 hours. React at 45°C for 24 hours; obtain the product after the demoulding step; after drying, paint the outer surface of the product with acrylic paint.

[0036] The surface of the product obtained in Example 2 is smooth and dense, high in strength, light in overall weight, and has good internal integrity without delamination. At the same time, the overall waterproof performance is greatly improved, and the surface strength is i...

Embodiment 3

[0038]In order to obtain a product with a smooth and dense surface layer and a light overall weight, the inner wall of the mold is now coated with a layer of special defoamer. The defoamer contains an appropriate amount of silicone defoamer modified silicone oil, 10 wt Part surfactant, 100 parts by weight water. Then inject PLHC light slurry, and then carry out the following treatment together with the mold, stand at room temperature for 3 hours, and then react at 45°C for 24 hours; the product is obtained after the demoulding step; after drying, the product is Paint the exterior with acrylic paint.

Abstract

The invention relates to a manufacturing method of a lightweight building curtain wall plate, and belongs to the field of new building materials. The manufacturing method of the lightweight building curtain wall plate comprises the following steps that S1, PLHC light raw material slurry is mixed and stirred; S2, the PLHC light raw material slurry is fully injected into a whole specified mold, andthen the PLHC light raw material slurry and the mold are dried and molded firstly under specified conditions, then the PLHC light raw material slurry reacts at the high temperature, so that the PLHC light raw material slurry is molded; S3, a demolding step is carried out; and S4, after a product is dried, the outer surface of the product is coated with an acrylic coating.

Description

technical field [0001] The invention relates to a method for manufacturing a lightweight building curtain wall panel, which belongs to the field of new building materials. The method of the present invention is particularly suitable for the preparation of materials for improving waterproof performance and increasing the surface strength of products. Background technique [0002] The construction industry is one of the pillar industries that affect the national economy and people's livelihood, with an annual output value exceeding 20% ​​of GDP. The main form of operation in the existing construction industry is cast-in-place concrete, which has many advantages such as simple technology, low cost, and the ability to absorb a large number of labor forces. It has made great contributions to the urbanization construction in the past 20 to 30 years. However, this form of operation has several obvious disadvantages: 1. The resource consumption is huge, and the precision is not hig...
