Problems solved by technology

[0003] At present, the prefabricated building wall panel is a reinforced concrete component. The manufacturing process is to make a steel mold according to the design requirements of the construction drawing, put the bound steel mesh and various embedded parts, and then pour the concrete and vibrate it densely, and steam curing for 6- After 9 hours, the strength of the concrete reaches 70% and the mold is demoulded. The disadvantages of this process are: ①The weight of the wall panels increases the size of the foundation,

Abstract

The invention discloses a fabricated light heat insulation wallboard for buildings. Water is added into a light heat insulation wallboard material to form liquid slurry through mixing, and then pouring forming is carried out in a disassembly-free mould. The light heat insulation wallboard material is prepared from, by weight, 80-85% of a cementing material, 10-17% of light heat insulation aggregate and 3-5% of a composite additive, wherein the sum of the weight percentages of the components is 100%, and the weight ratio of the added water to the cementing material is (0.50-0.60):1. The preparing technology of the fabricated light heat insulation wallboard for buildings includes the following steps that firstly, calcium silicate boards are prepared; secondly, the mould is prepared; thirdly, the composite additive and the cementing material are mixed and then doped with the light heat insulation aggregate, water is added, the mixture is stirred to be uniform and then poured into the mould, and after initial setting, final setting, carrying, stacking and curing, the finished product is obtained. By utilizing chemical gypsum, the fabricated light heat insulation wallboard for buildings is prepared and is light, good in fireproofness, waterproofness, heat insulation, sound insulation, compression resistance and fracture resistance and convenient to prepare and construct.

Description

Technical field [0001] The invention relates to the field of building thermal insulation wall materials, in particular to a prefabricated building lightweight thermal insulation wallboard and a manufacturing process. Background technique [0002] Industrial by-product chemical gypsum resources are very abundant in my country, and the comprehensive utilization rate is very low, causing serious environmental pollution and resource waste, especially phosphogypsum, whose annual output accounts for 1 / 3 of the total output of various chemical gypsum However, the utilization rate is only about 20%, its chemical composition is complex, the quality is very unstable, building materials have low compressive strength, efflorescence, and peculiar smell, and the water absorption of gypsum makes its products unable to be used in places such as kitchens and bathrooms. These factors have prevented the comprehensive utilization of such resources. In this regard, the state has issued a number of rel...
