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 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 paper pulp 10.

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

[0037] Add the remaining water to the cement and add waste paper pulp and foam successively under stirring. The whole is stirred for 1-3 minutes, and all are poured into the prefabricated tank or the target position to obtain a new type of waterproof and anti-cracking foamed cement.

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

Embodiment 2

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

[0051] Emulsifier OS 0.3

[0052] Sodium alkylbenzene sulfonate 0.18

[0053] Alkylbenzene 0.20

[0054] Water 900

[0055] Cement 900

[0056] Waste paper pulp 15.

[0057] The preparation process is the same as in Example 1.

Abstract

The invention discloses novel waterproof crack-resisting foaming cement. The novel waterproof crack-resisting foaming cement is formed by uniformly mixing the following substances in part by weight: 0.1-0.5 part of emulsifying agent, 0.05-0.25 part of sodium alkyl benzene sulfonate, 0.05-0.25 part of alkylbenzene, 800-1000 parts of water, 800-1000 parts of cement and 10-15 parts of waste paper pulp. The invention further discloses a production method of the novel waterproof crack-resisting foaming cement. The novel waterproof crack-resisting foaming cement disclosed by the invention has the advantages of waterproof crack-resisting performances, fewer material components, economy of resource, and reduction of cost.

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.
