Embodiment 1

[0011] The preparation method of multifunctional building waterproofing agent comprises the following steps:

[0012] (1) Add 20 parts of talcum powder, 30 parts of water and 5 parts of sodium chloride into the container by weight and stir evenly;

[0013] (2) Add 1 part by weight of sodium hydroxide, 6 parts of gelatin, 5 parts of urea and 1 part of boric acid to the mixed material in the step (1) and stir evenly for 20 minutes to obtain the product.

[0014] The stirring speed is 70r / min. In this embodiment, because of its air permeability, the waterproofing agent will not expand, deform and weather, which can improve durability and prolong the service life of the building.

Embodiment 2

[0016] The preparation method of multifunctional building waterproofing agent comprises the following steps:

[0017] (1) Add 25 parts of talcum powder, 40 parts of water and 8 parts of sodium chloride into the container by weight and stir evenly;

[0018] (2) Add 2 parts by weight of sodium hydroxide, 7 parts of gelatin, 6 parts of urea and 1.5 parts of boric acid to the mixed material in the step (1) and stir evenly for 25 minutes to obtain the product.

[0019] The stirring speed is 75r / min.

Embodiment 3

[0021] The preparation method of multifunctional building waterproofing agent comprises the following steps:

[0022] (1) Add 30 parts of talcum powder, 50 parts of water and 10 parts of sodium chloride into the container by weight and stir evenly;

[0023] (2) Add 3 parts by weight of sodium hydroxide, 8 parts of gelatin, 7 parts of urea and 2 parts of boric acid to the mixed material in the step (1) and stir evenly for 30 minutes to obtain the product.

[0024] The stirring speed is 80r / min.

Abstract

The invention relates to the technical field of waterproofing agents, and in particular relates to a preparation method of the multifunctional building waterproofing agent. The method comprises the following steps of: (1), adding 20-30 parts by weight of talcum powder, 30-50 parts by weight of water and 5-10 parts by weight of sodium chloride into a container and uniformly mixing; and (2), adding 1-3 parts by weight of sodium hydroxide, 6-8 parts by weight of gelatin, 5-7 parts by weight of urea and 1-2 parts by weight of boric acids into a mixed material obtained in the step (1) and uniformly stirring for 20-30 minutes to obtain a product. The preparation method has good waterproof effect; through the reaction with alkali substances in cement or masonry, gaps between mortar and concrete are compact, so that the compactness degree of the product is correspondingly improved and the aim of waterproofing is fulfilled; and meanwhile, the waterproofing agent is short in curing time and is not affected by external environment during construction, and the construction can be carried out at all seasons; and a finished product can be maintained for 5 years at 40 DEG, and the harm to the human and three-wastes pollution are avoided; and therefore, the multifunctional building waterproofing agent is an environment-friendly product.

Description

technical field [0001] The invention relates to the technical field of waterproofing agents, in particular to a preparation method of a multifunctional building waterproofing agent. Background technique [0002] At present, the waterproofing of various buildings is a key issue. Commonly used waterproof materials are various types of waterproof membranes, waterproof coatings, waterproof cement, etc. Waterproof membranes are generally hot construction, mostly baked by fire, the main disadvantage is that the bonding is not comprehensive, there are seams, and some special parts, such as corners, nozzles, etc. Not easy to repair. In addition, the existing waterproofing agent has poor waterproofing effect, inconvenient construction, produces toxic smell to human body, and causes environmental pollution. Contents of the invention [0003] The object of the present invention is to provide a preparation method of a multifunctional building waterproofing agent with short curing t...
