Embodiment 1

[0017] A kind of organosilicon waterproof coating of the present invention, is made up of the component of following parts by weight,

[0018]

[0019] The main component of the KH550 type silane coupling agent is 3-aminopropyltriethoxysilane.

[0020] The main component of the 602 defoamer is hexameric dioleate.

Embodiment 2

[0022] A kind of organosilicon waterproof coating of the present invention, is made up of the component of following parts by weight,

[0023]

[0024]

Embodiment 3

[0026] A kind of organosilicon waterproof coating of the present invention, is made up of the component of following parts by weight,

[0027]

[0028] Working process of the present invention:

[0029] During the working process of the organosilicon waterproof coating of the present invention, the coating can penetrate several millimeters into the wall and form a mesh waterproof film on the surface and inside of the wall to improve the waterproof effect. The waterproof film will not close the capillary pores of the base material, and the moisture can still Scatter from the inside of the wall to achieve waterproof and breathable effect; the paint is non-toxic, non-irritating, non-flammable, non-explosive, non-volatile, miscible with water, environmentally friendly and safe; good wear resistance, long service life; Chemical effect, no corrosion to steel bars, wide application range; easy to use, low cost.

Abstract

The invention discloses an organosilicon waterproof coating material. The organosilicon waterproof coating material is prepared from the following ingredients in parts by weight: 30-50 parts of methyl silicate, 20-30 parts of dimethyl siloxane, 3-5 parts of a silane coupling agent, 10-15 parts of methyl silicone oil, 0.2-1 part of an antifoamer, 5-10 parts of deionized water and 10-20 parts of silicon dioxide. The coating material disclosed by the invention can permeate into a wall by several millimeters and form reticular waterproof films on the surface and interior of the wall so as to improve the waterproof effect, the waterproof films cannot close capillary pores of a base material, and moisture still can spread out from the interior of a wall body, so that waterproof and air-permeable effects are achieved; the coating material is non-toxic, non-combustible, non-explosive, non-volatile, environment-friendly and safe, is free from irritant odors and can be mixed and dissolved with water; the wear resistance is good, and the service life is long; the coating material has a passivating action, is un-rusty to reinforcing steel bars and is wide in range of use; the use is convenient, and the cost is low.

Description

【Technical field】 [0001] The invention relates to the technical field of architecture, in particular to the technical field of silicone waterproof coatings. 【Background technique】 [0002] Waterproof coatings are needed in construction. The existing architectural waterproof coatings mainly include polyurethane waterproof coatings, polymer cement waterproof coatings, asphalt waterproof coatings and modified emulsified asphalt waterproof coatings, polymer bitumen waterproof coatings, and silicone rubber waterproof coatings. Wait. Among them, modified emulsified asphalt waterproof coatings have low tensile strength and elongation at break after film formation, and are prone to secondary pollution. The non-exposed two-component coating represented by polyurethane tar has certain toxicity, and the construction base layer must be dry, and the two components have a certain ratio, and the construction requirements are strict. 【Content of invention】 [0003] The purpose of the pr...
