Abstract

The invention discloses a thermal insulation and waterproof building heat preservation asbestos board, which is composed of the following components by weight: 60-70 parts of asbestos powder, 12-14 parts of nano diatomite powder, 12-15 parts of white wall powder dreg, 10-12 parts of papermaking waste residue, 8-10 parts of mineral fiber, 5-7 parts of limestone, 3-5 parts of calcium sulfate whisker, 12-14 parts of rice husk, 2-4 parts of a curing agent, 2-3 parts of carboxylated nitrile rubber, 2-3 parts of redispersible latex powder, 3-5 parts of chlorinated paraffin, 2-4 parts of a UV absorbent, and 50-60 parts of water. The asbestos board provided by the invention adopts asbestos powder and nano diatomite powder as the raw materials, and is prepared by a press method, the preparation process is simpler and easy for industrialization, and the material cost is low.

Description

technical field [0001] The invention relates to the field of asbestos boards, in particular to a thermal insulation and waterproof building insulation asbestos board. Background technique [0002] Asbestos board is the abbreviation of asbestos fiber cement board, which is produced according to scientific formula with asbestos, glass fiber, clay and other materials. It has strong tensile strength and pressure resistance, and can withstand about 1400 °C. It can be used for heat insulation, heat insulation and sound insulation, boilers, steel plants, chemical plants, aluminum casting plants, etc., as well as general electrical insulation. [0003] The existing thermal insulation asbestos boards all adopt traditional production methods, which have low efficiency and high cost, and the quality of the prepared asbestos boards is not ideal, the thermal insulation and sound insulation effect is not good, and it is difficult to maintain if there is damage.
