Preparation process of thermal insulation type expanded perlite composite material for building

Abstract

The invention discloses a preparation process of a thermal insulation type expanded perlite composite material for buildings, and belongs to the technical field of building materials. Expanded perlite can be subjected to crushing and grading treatment to be sorted into large-particle-size expanded perlite and small-particle-size expanded perlite, and meanwhile, foam raw materials are subjected to infiltration treatment to obtain the thermal insulation type expanded perlite composite material for buildings. The preparation method comprises the following steps: mixing expanded perlite with small particle size with mortar powder, filling the mixture into a counterweight belt, putting a foam raw material into the counterweight belt, naturally rolling, and adsorbing the expanded perlite and the mortar powder in the rolling process to complete weight increment, so that the foam raw material after weight increment has certain strength, and the foam raw material has the advantages of high strength, high strength, high strength, high strength and the like. Meanwhile, the weight of the expanded perlite is similar to that of expanded perlite with large particle size, the expanded perlite can be fully and uniformly mixed, and finally, the forming quality can be effectively improved in the compounding process.

Description

technical field [0001] The invention relates to the technical field of building materials, and more specifically relates to a preparation process of thermal insulation expanded perlite composite material for building. Background technique [0002] With the worldwide energy shortage and the environmental problems brought about by energy utilization, resources, energy and environmental protection are the three major tests restricting the sustainable development of human society and economy today. effective way of development. In addition to the efficient conversion of energy and the rational development of renewable energy, fully improving the efficiency of energy utilization is also the key to energy conservation. Thermal insulation materials can effectively reduce the heat loss accompanying heat generation, transportation, storage and use, and are widely used in construction, chemical industry, electronics, clothing, aerospace and other fields. important way to reduce emis...

Problems solved by technology

[0004]Expanded perlite and recycled foam materials are commonly used in construction, which not only has good thermal insulation performance, but also saves resources. However, due to the relatively high density of foam materials Low, it is difficult to mix evenly when mixed with expanded perlite, because expanded perlite is dense and heavy, so there is always a tendency to settle down during the mixing process, resulting in poor molding quality in the final compounding process
