Calcium silicate plate with high fire resistance and production process thereof

Abstract

The invention discloses a calcium silicate plate with high fire resistance and a production process thereof. The calcium silicate plate comprises each following component with the percent content by mass: 1 to 3 percent of sodium silicate, 0.5 to 2 percent of iron oxide red, 10 to 20 percent of mica, 9 to 12 percent of asbestos, 2.5 to 3.5 percent of paper fibre, 38 to 45 percent of quartz sand, 8 to 18 percent of cement, 10 to 30 percent of calcium carbide mud and 8 to 12 percent of water. According to the calcium silicate plate with the high fire resistance and the production process thereof, the fireproof performance is excellent, and the fire endurance even can be greater than the highest limit of 4 hours in a standard at present. Other performances are also high comparatively and completely reach the quality requirement of a relevant standard. Meanwhile, local materials are used, the price of the raw materials is cheap, some raw materials can also be recycled, wastes are changed into valuables, the consumption of raw ore substances is reduced, and the calcium silicate plate is very friendly to the environment.

Description

technical field [0001] The invention relates to a building material improvement technology, in particular to a high fire-resistant calcium silicate board and its production process, belonging to the technical field of building materials. Background technique [0002] Calcium silicate board is one of the important wall materials in modern buildings, because of its low, medium and high density (0.8-1.5 g / cubic centimeter), fire prevention (its combustion performance reaches GB8624 non-combustible class A), and strong sound insulation , anti-corrosion and moisture-proof, high strength (10-17 MPa), easy processing, light construction, smooth and beautiful surface, etc., are widely used in various modern buildings, as indoor partition walls, partition walls, floors, ceilings, furniture etc. The existing calcium silicate board production mainly uses a large amount of raw minerals and their processed materials, such as pearl sand, quartz powder, river sand, china clay, kaolin, cem...

AI Technical Summary

Problems solved by technology

The calcium silicate board produced by this method has many kinds of raw materials, low fire protection level, and it is difficult to obtain various raw materials locally, resulting in high cost and can not achieve the effect of low price and good quality

In today's densely populated cities, the fire protection level of building materials must be improved, and its fire protection quality cannot meet today's needs, and the appearance is not delicate enough.
