AI Technical Summary

Problems solved by technology

Some of these waterproof measures exist, such as waterproof coiled materials, which are complex in construction, unsanitary, pollute the environment, are toxic to humans and animals, have poor anti-aging ability, and cannot be used for drinking water for humans and animals and waterproof projects that are in close contact with humans and animals. Coal is used in waterproof coatings. Tar contains benzene, xylene, naphthalene, anthracene, phenol, quinone and other harm

Example Embodiment

[0041] Example 1

[0042] The preparation of waterproof rubber powder for roofing requires impermeability, waterproof, crack resistance, compression resistance and excellent performance. The mixing ratio of the waterproof rubber powder is (calculated by weight percentage): aluminosilicate 35%, hydrated silicate 17.65%, silicon dioxide 15%; calcium powder 10%; mineral powder 10%; rubber powder 10%; Plasticizer 0.8%; Thickener 0.3%; Organic silicon 1.0%; Coagulant 0.1%; Anti-cracking agent 0.15%.

Example Embodiment

[0043] Example 2 (take 1000kg as an example)

[0044] Add 350kg of aluminosilicate, 250kg of hydrated magnesium silicate, 100kg of silicon powder, 50kg of calcium powder, and 100kg of first-grade coal ash into a 1000L mixer. Start the mixer and mix for ten minutes.

[0045] Add 95 kg of ethylene and vinyl chloride and ethyl laurate terpolymer rubber powder into a 500L mixer (device), add 10 kg of polycarboxylate plasticizer and 4 kg of hydroxyethyl methyl cellulose during the mixing process. 20kg of siloxane, 20kg of calcium formate, 1kg of polypropylene fiber, after adding it, stir for 20 minutes, make it fully mixed, and stop the machine. Put the mixture into a 1000L mixer and mix with the siliceous composite material for 15 minutes. After agglomerating and dispersing uniformly, the metering package is 1000KG of waterproof rubber powder composition, model SJ601A.

Example Embodiment

[0046] Example 3 (take 1000kg as an example)

[0047] Using a 1000L mixer, add 350kg of high-performance silicate powder, 200kg of calcium silicate, 200kg of silicon dioxide, and 50kg of first-grade coal powder while stirring. After stirring for 10 minutes, add 2kg of anti-cracking agent fiber and hydroxyl. Ethyl cellulose 5kg, sulfamate 15kg, silane 30kg, sodium thiosulfate 30kg, vinyl acetate and ethylene copolymer binary rubber powder 118kg, after adding it, continue to stir for 20 minutes, make it fully mixed and then measure The packaging is waterproof rubber powder 1000KG, model SJ601B.

[0048] Table 1 shows the performance indexes of waterproof, anti-corrosion and anti-crack using the waterproof rubber powder of the present invention. The test refers to JC / T894-2001, JC474-1999.

Abstract

The present invention is one kind of waterproof adhesive powder composition and its preparation process. The waterproof adhesive powder composition consists of aluminosilicate powder 30-40 wt%, hydrous siliate powder 15-35 wt%, silica powder 5-15 wt%, calcium carbonate powder 5-15 wt%, mineral powder 5-15 wt%, ethylene glue powder 5-15 wt%, plasticizer 0.5-1.5 wt%, thickener 0.2-0.5 wt%, organosilicon 1-3 wt%, coagulation accelerator 0.1-0.3 wt%, and anticracking agent 0.05-0.15 wt%.

Description

technical field [0001] The invention relates to a composition, in particular to a waterproof rubber powder composition for construction and a preparation method thereof. Background technique [0002] Among the building construction materials, concrete, mortar, brick, stone, tile, and natural stone are the main body of the building. Its durability determines the service life of the building, because it is a porous building material composed of inorganic salts. It has a destructive effect on it. Whether it is acid water, alkaline water, natural water, or water vapor, it can quickly enter the gaps in the building, eroding the building at all times to form chemical erosion, shrinkage cracks, shrinkage cracks, thermal expansion and cold Shrinkage cracks, after water freezes in the building, it will form ice crystals that are several times larger than the volume of water and expand, causing serious damage to the structure and significantly shortening the service life of the buildi...
