preparation example Construction

[0020] Another aspect of the present invention provides a kind of preparation method of above-mentioned modified acrylate spray film waterproofing material, and this preparation method comprises: mixing acrylate aqueous solution, water-based emulsion and optional pigment and / or auxiliary agent uniformly, divide into A, Two parts of B are mixed with oxidizing agent and reducing agent respectively. The "mixing with the oxidizing agent and the reducing agent separately" means that one part is mixed with the oxidizing agent, and the other part is mixed with the reducing agent.

[0021] According to the present invention, preferably, the ratio of the A part to the B part is 0.01:1-1:0.01.

[0022] As a preferred solution, all raw materials for preparing the modified acrylate spray film waterproofing material of the present invention can be obtained commercially.

Embodiment 1

[0026] In parts by weight, the raw materials for preparing the waterproof material of this embodiment are: 100 parts of calcium acrylate aqueous solution with a mass concentration of 45%, 20 parts of styrene-acrylic emulsion, 1 part of sodium persulfate, 0.5 part of ferrous sulfate, heavy carbonic acid 30 parts of calcium, 1992 parts of defoamer B.

[0027] Concrete preparation steps are as follows:

[0028] Mix calcium acrylate aqueous solution, styrene-acrylic emulsion, powder and additives, disperse at high speed, stir evenly, divide into two parts A and B according to the ratio of 1:1, and add sodium persulfate and ferrous sulfate respectively.

Embodiment 2

[0030] In parts by weight, the raw materials for preparing the waterproof material of this embodiment are: 100 parts of magnesium acrylate aqueous solution with a mass concentration of 45%, 50 parts of pure acrylic emulsion, 2 parts of ammonium persulfate, 3 parts of sodium bisulfite, light carbonic acid Calcium 50 parts, defoamer DF-88682 parts, anti-sedimentation agent TN601 3 parts.

[0031] Concrete preparation steps are as follows:

[0032] Mix magnesium acrylate aqueous solution, pure acrylic emulsion, powder and additives, disperse at high speed, stir evenly, divide into two parts A and B according to the ratio of 1:1, and add ammonium persulfate and sodium bisulfite respectively.

Abstract

The invention discloses a modified acrylate spray membrane waterproofing material and a preparation method thereof. Raw materials for preparation of the waterproofing material comprise (by weight): 100 parts of an acrylate aqueous solution, 10-100 parts of an aqueous emulsion, 0.5-10 parts of an oxidizing agent, 0.5-10 parts of a reducing agent, 0-100 parts of a pigment and 0-10 parts of an auxiliary agent. According to the invention, the problem that a film of an acrylate spray membrane waterproofing material is easy to crack at low humidity can be effectively solved. By professional equipment for construction, toughness of the acrylate spray membrane waterproofing material can be maintained for a long time, and the acrylate spray membrane waterproofing material is applicable to waterproofing works of subway, urban underground utility tunnels, tunnels and underground engineering, etc.

Description

technical field [0001] The invention belongs to the field of waterproof materials, and more specifically relates to a modified acrylate spray film waterproof material and a preparation method thereof. Background technique [0002] Waterproof materials are used as building envelopes to prevent the penetration of rainwater, snowwater and groundwater; to prevent the erosion of moisture, steam and other harmful gases and liquids in the air; as a separation structure to prevent seepage of water supply and drainage. These anti-penetration, leakage and erosion materials are collectively referred to as waterproof materials. There are many kinds of waterproof materials, and new waterproof materials emerge in endlessly. [0003] Japanese Patent No. 61-19683 discloses a film-forming component using acrylic acid or its derivatives, and simultaneously contains oxidizing agents, reducing agents, aggregate filling components and auxiliary components, and water, etc. as film-forming spray ...
