Problems solved by technology

Wherein the osmotic crystalline waterproofing agent accounts for 16% to 20% of the weight of the composite osmotic crystalline waterproofing agent, and the calcined attapulgite clay at 850°C accounts for 80% to 84% of the weight of the composite osmotic crystalline waterproofing agent, and the calcining temperature of the attapulgite clay is 400℃~950℃, calcination time is 0.5~3.5 hours, this invention, although the bonding strength is improved, but the waterproof and impermeable performance is still average
[0004] Another example is the invention patent with the Chinese application number 201810633273.8 disclosing a self-healing high-efficiency permeable crystalline building waterproof material, which is a water-soluble white emulsion prepared from the following ingredients by weight percentage: sodium methyl silicate 60%, pure Acrylic emulsion 10%, water-swellable resin 8%, silicon dioxide 6%, triethanolamine 6%, toughening agent 4%, anti-aging agent 2%, gelatin 2%, defoamer 1%, storage stabilizer 1%; The disadvantage of this invention is that after crystal growth, internal stress will be formed in the middle of the crack, reducing the compressive strength

When being applied in waterproof materials, the permeable crystallizing material enables the waterproof materials to have good waterproof performance and mechanical performance, and the permeable crystallizing material can be widely applied in the field of building.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to an infiltration crystalline material and a preparation method. Background technique [0002] Cement-based permeable crystalline waterproof materials have won the favor of people from all walks of life due to their comprehensive advantages. However, the current waterproof material market is mixed, especially the cement-based permeable waterproof materials are uneven, and the waterproof effect and mechanical properties cannot be guaranteed. A large number of user complaints, so there is an urgent need for a permeable crystalline material, which can be used in cement to solve the problems in the waterproof industry. [0003] For example, the invention patent with the Chinese application number of 200810196373.5 discloses a composite osmotic crystalline waterproofing agent, which is a composite of the existing osmotic crystalline waterproofing agent and calcined attapulgite clay, w...
