preparation example Construction

[0014] The present invention also provides a method for preparing the above-mentioned silicone rubber waterproof coating, the method comprising: mixing the silicone rubber emulsion with water to form a feed liquid; then mixing calcium carbonate, anti-rust pigment, adhesive, thickener, moisture-proof Agent and organic silicon are added to the material liquid and stirred and mixed to obtain a silicone rubber waterproof coating.

[0015] In the above-mentioned preparation method, there is no special limitation on the way of mixing. Preferably, the method of mechanical stirring is used for mixing, and the speed of mechanical stirring is 1500-2000rpm; in the above-mentioned preparation method, the time of stirring and mixing can be in a wide range Internal selection, but in order to further improve the production yield of silicone rubber waterproof coating, preferably, the time of stirring and mixing is 3-8h.

Embodiment 1

[0018] Select a reaction vessel, add the following raw materials in parts by weight: 30 parts of silicone rubber emulsion and 5 parts of water, and mix them mechanically to form a feed liquid; then add 5 parts of calcium carbonate, 3 parts of barite powder, 10 parts of phenolic-polymer Amide, 1 part of styrene-butadiene rubber, 2 parts of quicklime and 10 parts of silicone were added to the feed solution, and the mixing time was 3 hours at a speed of 2000 rpm to prepare the silicone rubber waterproof coating A1.

Embodiment 2

[0020] Select a reaction vessel, add the following raw materials in parts by weight: 60 parts of silicone rubber emulsion and 20 parts of water, and mix them mechanically to form a feed liquid; then add 10 parts of calcium carbonate, 10 parts of talcum powder, 20 parts of phenolic-epoxy Resin, 6 parts of polyurethane, 5 parts of silica gel and 10 parts of silicone were added to the feed solution, and the mixing time was 8 hours at a speed of 1500 to prepare the silicone rubber waterproof coating A2.

Description

technical field [0001] The invention relates to a waterproof coating, in particular to a silicone rubber waterproof coating and a preparation method thereof. Background technique [0002] Paint is a material that can be coated on the surface of a protected or decorated object by different construction techniques, and can form a solid film with firm adhesion, certain strength, and continuity with the object to be coated. The formed film is commonly called coating film, also known as paint film or coating. Coatings are usually a mixture of resins, oils, emulsions, pigments, additives and other preparations, prepared with organic solvents or water. Coatings are widely used, such as colored paintings coated on the surface of objects based on the decorative function of paint, anti-corrosion and moisture-proof coatings coated on the surface of objects based on the protective function of paint, etc. According to different uses of coatings, there are different aspects and degrees ...
