Embodiment 1

[0038] Example 1 Preparation of nano-ceramic composite coating

[0039] In parts by weight, the nano-ceramic composite coating includes the following components:

[0040] 10 parts of deionized water, 75 parts of inorganic resin, 40 parts of pigment and filler, 2 parts of wetting agent, 3 parts of dispersing agent, 1 part of defoamer, 1 part of film-forming aid, 2 parts of leveling agent, 3 parts of thickener parts, curing agent 1-3 parts and other raw materials.

[0041] The inorganic resin in this embodiment mainly includes silica nano-sol, the wetting agent is polyoxyethylene alkylated ether, the dispersant is acrylic polymer, the defoamer is ethylene oxide, and the film-forming aid is silane The coupling agent (KH-550), the leveling agent is polydimethylsiloxane, the thickener is silicate, and the curing agent is poly-type two-component silicone rubber crosslinking agent (RTV-2).

[0042] The preparation process of silica nano sol is as follows: dissolve ethyl orthosilica...

Embodiment 2

[0052] Use the unsaturated polyester resin SMC waterproof plate with a thickness of 4mm as the base plate, and follow the steps below:

[0053] 1. The surface of the waterproof plate is not sandblasted

[0054] The surface of the waterproof plate in this embodiment is guaranteed to be dry and free from defects such as stains and impurities.

[0055] 2. Paint preparation:

[0056] A deployment ratio (mass ratio):

[0057] Primer (red): diluent: hardener=18:7:1, toner is red toner;

[0058] Sprinkle paint (black dots+white dots): diluent: hardener = 18:7:1, the toner is black and white toner;

[0059] Topcoat (transparent varnish): diluent: hardener = 18:7:1, no pigment;

[0060] The hardener is methyl silane coupling agent, and the diluent is ethylene glycol-ether paint thinner.

[0061] B spraying sequence: primer-sprinkling paint-finish, clean the spray gun repeatedly with acetone after each spraying.

[0062] 3. Surface spraying:

[0063] Primer spraying: Filter the p...

Embodiment 3

[0070] Use the unsaturated polyester resin SMC waterproof plate with a thickness of 4mm as the base plate, and follow the steps below:

[0071] 1. Sand blasting treatment on the surface of the waterproof plate:

[0072] Place the inner surface of the waterproof pan body facing up at 45°, and perform sandblasting and polishing on the inner surface. When sandblasting, the gun head rotates clockwise at a constant speed and moves from left to right until the inner surface of the waterproof disc body is completely polished and rough. After the grinding is completed, use compressed air to clean the residual sand on the surface to ensure that the surface is oil-free, water-free and dry. , No other impurities such as stains, the inner surface of the waterproof plate body is treated and placed horizontally to be sprayed. The sand material used in this embodiment is 120# brown corundum, the working air pressure is 0.6-0.8Mpa, the equipment is a sandblasting machine, and its gun head is...

Abstract

The invention discloses a waterproof plate which comprises a waterproof plate body and a nano-composite ceramic coating layer covering the inner surface of the waterproof plate body. The nano-composite ceramic coating layer sequentially comprises a priming paint layer, a spot paint layer and a finishing paint layer from bottom to top; the priming paint layer, the spot paint layer and the finishingpaint layer are respectively formed through spraying a priming paint, a spot paint and a finishing paint. The nano-composite ceramic coating layer covers the surface of the waterproof plate providedby the invention and is formed by a nano-composite ceramic coating. An inorganic resin of a nano sol-gel is added into the nano-composite ceramic coating, so that the product surface has higher film hardness, better weather resistance and excellent chemical corrosion resistance; the construction can be carried out conveniently, the materials are saved, the waterproof plate is environmental-friendly and non-toxic, various overall properties such as wear resistance, hardness, weather resistance, skid resistance, fast dryness, chemical corrosion resistance, and easiness in cleaning of the waterproof plate can be remarkably improved, and the color of the nano-composite ceramic coating can be changed through adding pigments and fillers, so that the waterproof plate is more attractive.

Description

technical field [0001] The invention relates to the technical field of bathroom product manufacturing, in particular to a waterproof pan and a preparation method of the waterproof pan. Background technique [0002] Sheet Molding Compound (SMC, Sheet Molding Compound) is made of raw materials such as unsaturated polyester resin, low shrinkage additives, fillers, curing agents, thickeners, release agents and glass fibers mixed into a resin paste, impregnated with chopped fiber roving Or glass fiber felt, impregnated with glass fiber by a sheet molding compound machine to make a sheet, and wrap it with polyethylene or polypropylene film on both sides, roll it up, and then thicken it to achieve a non-sticky state , for molding. Sheet molding compound is a molding compound developed in the 1960s to manufacture fiber-reinforced plastics by dry method. It first appeared in Europe, and then the United States and Japan successively developed this process. After more than 40 years of...
