Problems solved by technology

[0002] There are many existing new waterproof and anti-cracking foaming cement technologies and inventions, but their compositions are more complicated and different, such as: sodium alkylbenzene sulfonate, triethanolamine, polycarboxylic acid, hydrogen peroxide, dynamic cement, etc. A combination of vegetable protein glue, rosin, etc.; polypropylene monofilament fiber, lignin fiber, water-resistant glue powder and hydroxypropyl methylcellulose are useful for crack resistance; stearic acid, sodium stearate, and stearic acid are useful for waterproofing. Calcium acid, redispersible rubber powder, water-resistant rubber powder, etc., and the waterproof performance is single, or in use, a waterproof layer is added, the construction is cumbersome, resulting in waste of resources and high cost

Embodiment 1

[0029] A new type of waterproof and anti-cracking foamed cement, which is made by mixing the following substances by weight:

[0030] Emulsifier OS 0.1

[0031] Sodium alkylbenzene sulfonate 0.25

[0032] Alkylbenzene 0.05

[0033] water 1000

[0034] Cement 800

[0035] Waste pulp 10.

[0036] Add emulsifier OS, sodium alkylbenzene sulfonate and alkylbenzene into 0.3 kg of water, heat to 50°C with stirring, and keep warm for 2 hours to prepare a waterproof foaming agent, dilute 20 times with water, and get foam after inflating .

[0037] Add the remaining amount of water to the cement and stir, add waste paper pulp and foam in turn, stir for 1-3 minutes as a whole, pour all into the prefabricated tank or the target position, and you can get a new type of waterproof and crack-resistant foamed cement.

[0038] Among them, waste paper pulp can be formed by mixing, soaking or heating, stirring and crushing paper and water with a weight ratio of 1:6-10. The above-mentioned ...

Embodiment 2

[0041] A new type of waterproof and anti-cracking foamed cement, which is made by mixing the following substances by weight:

[0042] Emulsifier OS 0.5

[0043] Sodium alkylbenzene sulfonate 0.05

[0044] Alkylbenzene 0.25

[0045] water 800

[0046] Cement 1000

[0047] Waste paper pulp 15.

[0048] The preparation process is the same as in Example 1.

Embodiment 3

[0050] A new type of waterproof and anti-cracking foamed cement, which is made by mixing the following substances by weight:

Abstract

The invention discloses a novel waterproof and anti-crack foaming cement, which is prepared by mixing the following materials in parts by weight: emulsifier OS0.1-0.5, sodium alkylbenzenesulfonate 0.05-0.25, alkylbenzene 0.05-0.25, Water 800-1000, cement 800-1000, waste paper pulp 10-15. A preparation method of the novel waterproof and anti-crack foaming cement is also disclosed. The novel waterproof and anti-crack foaming cement itself has the performance of waterproof and anti-crack, has less material composition, saves resources and reduces costs.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a novel waterproof and anti-crack foaming cement used for thermal insulation and waterproofing of roofs, indoor cushions and external walls, and a preparation method thereof. Background technique [0002] There are many existing new waterproof and anti-cracking foaming cement technologies and inventions, but their compositions are more complicated and different, such as: sodium alkylbenzene sulfonate, triethanolamine, polycarboxylic acid, hydrogen peroxide, dynamic cement, etc. A combination of vegetable protein glue, rosin, etc.; polypropylene monofilament fiber, lignin fiber, water-resistant glue powder and hydroxypropyl methylcellulose are useful for crack resistance; stearic acid, sodium stearate, and stearic acid are useful for waterproofing. Calcium acid, redispersible rubber powder, water-resistant rubber powder, etc., and the waterproof performance is single, o...
