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 harmful substances, which are seriously poisonous to humans and animals, and also pollute the environment. After construction, the anti-aging ability is at most 5-8 years, so most waterproof coatings have been announced by the Ministry of Construction Prohibited and restricted use; chemical waterproofing agent, which belongs to rigid waterproof material, has very good anti-aging performance, but poor crack resistance and deformation, and it is easy to cause water leakage

Embodiment 1

[0042] Preparation of waterproof rubber powder for roofing requires impermeability, waterproof, crack resistance, compression resistance, and excellent performance. The mixing ratio of its waterproof rubber powder is (calculated by weight percentage): 35% of aluminosilicate, 17.65% of hydrated silicate, 15% of silicon dioxide; 10% of calcium powder; 10% of mineral powder; 10% of rubber powder; 0.8% plasticizer; 0.3% thickener; 1.0% silicone; 0.1% coagulant; 0.15% anti-cracking agent.

Embodiment 2

[0043] Embodiment 2 (taking 1000kg as example)

[0044] Add 350kg of aluminosilicate, 250kg of hydrated magnesium silicate, 100kg of silicon powder, 50kg of calcium powder, and 100kg of primary coal ash into a 1000L mixer, start the mixer, and stir for ten minutes.

[0045] In the stirrer (device) of 500L, add ethylene and vinyl chloride and ethyl laurate terpolymer rubber powder 95kg, add sodium polycarboxylate plasticizer 10kg, hydroxyethyl methylcellulose 4kg in the process of stirring, Siloxane 20kg, calcium formate 20kg, polypropylene fiber 1kg, stir for 20 minutes after the addition is complete, make it fully stirred and then stop the machine, input the mixture into a 1000L mixer and mix with the silicon composite material for 15 minutes, no aggregates and no After agglomeration and uniform dispersion, measure and pack as waterproof rubber powder composition 1000KG, model SJ601A.

Embodiment 3

[0046] Embodiment 3 (taking 1000kg as example)

[0047] With 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, hydroxyl Ethyl cellulose 5kg, sulfamate 15kg, silane 30kg, sodium thiosulfate 30kg, vinyl acetate and ethylene copolymer binary rubber powder 118kg, continue to stir for 20 minutes after the addition is complete, make it fully mixed before measuring The packaging is waterproof rubber powder 1000KG, and it is model SJ601B.

[0048] The performance index of waterproof, anti-corrosion and anti-cracking using the waterproof rubber powder of the present invention is illustrated by the test in Table 1, and the test reference standard is 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...
