Embodiment 1

[0042] The first step raw materials and pre-production preparation:

[0043] 1. Put 500 kg of fly ash, 50 kg of micro silica fume, 300 kg of calcium carbonate, 100 kg of quartz powder, 50 kg of talcum powder, and 50 kg of bentonite. Input the above materials into the raw material weighing hopper according to the weight data, and the raw material screw feeder Automatically metered and transported to the dry powder mixing and stirring equipment, the dry powder was mixed and homogenized for 15 minutes, and the degree of mixing and homogenization reached 99%, and then the finished dry powder after mixing and homogenization was put into the finished product storage bin for use.

[0044] 2. 1000 kg of styrene-butadiene latex and 100 kg of water-based epoxy resin are transported to a high-speed mixing homogenizer for use.

[0045] 3. Weigh 10 kg of wetting and dispersing agent (polyacrylate) for use.

[0046] 4. Weigh 5 kg of defoamer (isopropanol) for use;

[0047] The second step...

Embodiment 2

[0058] The first step raw materials and pre-production preparation:

[0059] 1. Put 250 kg of coal ash, 100 kg of silica fume, 100 kg of calcium carbonate, 250 kg of quartz powder, 100 kg of talcum powder, and 100 kg of bentonite into the solid waste discharged from thermal power plants. Raw material metering hopper and raw material screw feeder are automatically metered and transported to the dry powder mixing and stirring equipment. The dry powder is mixed and homogenized for 10 minutes, and the degree of mixing and homogenization reaches 99%. Then, the finished dry powder after mixing and homogenization is put into the finished product storage bin use.

[0060] 2. 500 kg of vinyl acetate-ethylene copolymer emulsion and 150 kg of water-based epoxy resin are transported to a high-speed mixing homogenizer for use.

[0061] 3. Weigh 5 kg of wetting and dispersing agent (naphthalene sulfonate condensation polymer) for use.

[0062] 4. Weigh 10 kg of defoamer (polypropylene gly...

Embodiment 3

[0074] Its specific content is similar to that of Example 1, except that organic color paste is added to the manufacturing materials of the product according to customer requirements, and iron oxide toner can also be added to prepare different color finishes.

[0075] That is to say, on the basis of maintaining its basic functions, the product complex water-based polymer waterproof coating of the present invention can add some functional materials (such as: toning) according to customer needs.

[0076] As a variation example of the present invention:

[0077] (1) water-based latex among the present invention can select pure acrylate emulsion, vinyl acetate-ethylene copolymer emulsion, styrene-acrylate copolymer emulsion, styrene-butadiene latex for use. These four kinds of emulsions have the advantages of low cost, not limited by regional materials and shortage factors caused by seasons, and sufficient supply.

[0078] (2) The inorganic low-gelling material in the present inv...

Abstract

The invention relates to a complex water-based polymer waterproof coating and a manufacturing method thereof. The manufacturing materials comprise the following components in parts by weight: A, organic liquid and B, inorganic fillers, wherein the organic liquid consists of 500-1000 parts of water-based latex, 100-150 parts of water-borne epoxy resin, 5-10 parts of wetting dispersant and 5-10 parts of antifoaming agent; and the inorganic fillers consist of 250-500 parts of inorganic low-cementitious material, 50-100 parts of silica fume, 100-300 parts of calcium carbonate, 100-250 parts of quartz powder, 50-100 parts of talcum powder and 50-100 parts of bentonite. The complex water-based polymer waterproof coating disclosed by the invention has the characteristics of good waterproof performance, durable weather resistance, stable performance, high temperature resistance, freeze thawing resistance, simplicity and convenience in construction, wide application range, utilization of industrial solid wastes and the like. In addition, the product is compounded into a pasty flowing slurry and is directly used on site, the cost is saved, and the defects such as dust pollution are avoided.

Description

technical field [0001] The invention relates to a waterproof paint for construction, in particular to a composite water-based polymer waterproof paint and a manufacturing method thereof. Background technique [0002] Building waterproofing occupies a very important position in the design and construction of architectural engineering, which is directly related to the normal use and life of buildings and structures. my country's waterproof materials have developed from a single variety to a multi-variety, multi-grade, and multi-functional waterproof material system. At present, waterproof materials are mainly divided into several categories such as waterproof coiled materials, waterproof coating films, and rigid waterproof materials. These types of waterproof materials have different quality problems and defects in use; [0003] 1. Due to the limitation of the width of the waterproof membrane, there are too many stitching seams. Thermal construction or adhesive construction is ...
