Abstract

The invention discloses a preparation method of a waterproof coating. The waterproof coating is prepared from raw materials in parts by weight as follows: 30-40 parts of polyurethane, 2-7 parts of cement, 2-8 parts of dimethyl silicone oil, 2.5-8 parts of ethylene-vinyl acetate copolymer, 20-26 parts of methylbenzene, 3-9 parts of aluminum chloride and 35-50 parts of water. The preparation method comprises steps as follows: water and polyurethane are added to a reaction kettle and stirred; the ethylene-vinyl acetate copolymer and the dimethyl silicone oil are added and stirred; the cement is added and stirred for 10 min; finally, methylbenzene and aluminum chloride are added and stirred for 5-10 min. The preparation method of the waterproof coating is simple, and a product has excellent waterproofness and higher strength, adhesive strength and tensile strength; the waterproof coating has excellent ageing resistance, weather resistance and ultraviolet radiation aging resistance and the product is durable.

Description

The preparation method of waterproof paint

Technical field

The present invention relates to building coating technical field, especially a kind of preparation method of waterproof paint.

Background technology

Along with the development of building trade, development and the application of all kinds of waterproof paint are developed rapidly, the quality and performance of building water-proof paint is had higher requirement, can ensure that buildings does not produce seepage or brushing waterproof paint just can shutoff seepage place after seepage.Common problem is to be exposed to the outermost coating of building, acid rain used under, outermost layer is damaged, and then built-in waterproof layer is destroyed, and coating is reduced the protective capability of architecture noumenon; In addition, there is larger harm to human body and environment in existing waterproof paint.

Summary of the invention

The object of this invention is to provide a kind of preparation method of waterproof paint, this waterproof paint possesses good waterproof, seepage control and weathering resistance, can solve the problem of existing waterproof paint water resistance difference.

In order to solve the problem, the technical solution used in the present invention is:

The preparation method of this waterproof paint is prepared from by the raw material of following parts by weight: polyurethane(s) 30 parts ~ 40 parts, cement 2 parts ~ 7 parts, dimethyl silicone oil 2 parts ~ 8 parts, ethylene-vinyl acetate copolymer 2.5 parts ~ 8 parts, toluene 20 parts ~ 26 parts, 3 parts ~ 9 parts, aluminum chloride, 35 parts ~ 50 parts, water;

Preparation method comprises the following steps:

A, in reactor, add water and polyurethane(s), stir 20 minutes ~ 30 minutes with the speed of 1000 revs/min ~ 1500 revs/min;

B, in reactor, add ethylene-vinyl acetate copolymer and dimethyl silicone oil, stir 20 minutes ~ 40 minutes with the speed of 600 revs/min ~ 800 revs/min;

C, in reactor, add cement, stir 10 minutes ~ 30 minutes with the speed of 600 revs/min ~ 1000 revs/min;

D, in reactor, add toluene and aluminum chloride, stir 5 minutes ~ 10 minutes with the speed of 600 revs/min ~ 1000 revs/min.

Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:

Waterproof paint of the present invention is base material with polyurethane(s), with the addition of water-resisting agent-aluminum chloride, and its preparation method is simple, and product waterproof property is excellent, and intensity is higher, and cohesive strength, tensile strength are higher; Have excellent ageing resistance, weathering resistance and antiultraviolet aging resistance, product is durable in use.
