Microwave modified inorganic cementing material, and preparation method and application thereof

Abstract

The invention discloses a microwave modified inorganic cementing material, and a preparation method and an application thereof. The microwave modified inorganic cementing material is prepared from, byweight, 20-50 parts of sulphoaluminate cement, 20-50 parts of water, 20-50 parts of silica powder, 5-15 parts of a sodium silicate solution, 0.1-1.5 parts of cellulose, 0.1-2 parts of lithium oxide,1-2 parts of industrial latex powder and 0.1-3 parts of air entraining agent. The inorganic cementing material has the advantages of simple raw material components, low cost, no harmful substances, environmental friendliness and remarkable reinforcing effect; the inorganic cementing material can be used for preparing wood boards, so the wood boards have the characteristics of environmental friendliness, no formaldehyde, no pollution, flame retardance and fireproofing, the national building material A1-level fireproof standard is met, the strength of the boards can reach or exceed the related requirements of wood density boards, furniture boards and bakelite boards, and boards have the characteristics of light weight and high strength; and the material can also be used for preparing building thermal insulation materials, lightweight cement partition board cores, floor heating base materials and the like, and has the characteristics of fireproofing, soundproofing, light weight, high strength, environmental friendliness and low cost, and the product strength is remarkably improved especially under a microwave irradiation condition.

Description

technical field [0001] The invention relates to a microwave-modified inorganic gelling material, a preparation method and application thereof, and belongs to the field of inorganic gelling materials. Background technique [0002] At present, there are a large number of standard boards made of wood chips, sawing waste, wood powder, small pieces of wood, wood blocks and organic gelling materials (mostly aldehydes, starches, and resin gelling materials) on the market. Types of boards mainly include multi-layer solid wood furniture boards, bakelite boards, and wood density boards. Such composite wood panels are widely used as a less expensive alternative to solid wood panels. However, since the preparation of such boards requires the use of organic gel materials, and the organic gel materials contain volatile or semi-volatile harmful substances, which in turn lead to pollution of the production environment and the use environment. Nowadays, the country's management of environm...

Problems solved by technology

[0003] At present, there are also some cement wood fiberboards on the market. These boards need to use silky wood fibers and be wrapped with cement. They have defects such as poor board strength. They can usually only be used as decorative boards. There is a big gap in the strength of glue board

[0004] In the prior art, it is used in the fields of building insulation materials, lightweight cement partition board cores, and floor heating substrates. There has always been a problem that high strength and light weight cannot be taken into account at the same time. Therefore, it is urgent to develop lightweight, high-strength, environmentally friendly, Low-cost products to meet social needs
