High-strength waterproof heat preservation material

Abstract

The invention discloses a high-strength waterproof and thermal insulation material, which is composed of the following raw materials in parts by weight: 8-12 parts of bentonite, 20-26 parts of cement, 20-30 parts of diatomite, and 40-50 parts of fly ash 10-18 parts of polyethylene foam, 5-9 parts of waterproofing agent, 4-8 parts of gelling material, 13-15 parts of calcium carbonate, and 5-10 parts of cellulose. The invention adopts a scientific raw material ratio, adopts diatomite, has no pollution to the environment, does not release toxic substances, and can improve indoor air; it solves the problem of energy saving and environmental protection, sound insulation, compressive strength and There are also insufficient problems in buildings with high thermal insulation performance requirements.

Description

technical field [0001] The invention relates to a high-strength waterproof and thermal insulation material, which belongs to the field of building materials. Background technique [0002] With the process of urbanization in China, the infrastructure construction is also expanding slightly, so the demand for building materials and the quality requirements are getting higher and higher. At present, most of the coatings used for building thermal insulation have poor weather resistance. When the external temperature changes greatly, the coating film will crack and other phenomena. However, the waterproof performance of the existing waterproof materials can only be waterproof in a single layer, and the waterproof performance is not strong enough. The preparation method is not simple enough, and the thermal insulation and fire resistance performance is not high. Contents of the invention [0003] In order to solve the above problems, the present invention provides a high-streng...
