Problems solved by technology

[0005] The coating surface of the existing corrosion-resistant elevator color-coated board has good toughness, high surface strength, and good corrosion resistance and scratch resistance. However, if it is used in a high-salinity environment, the PCM board will break After bending, the corresponding topcoat and primer coated on top will be stretched, the tensile properties of the topcoat and primer are poor, and some stretching will occur on the coating and primer after stretching. Small gaps, the salt spray solution in the air can easily penetrate between the coating and the substrate from the connection of the PCM board, causing peeling and peeling of the top coat and base coat

preparation example 1-3

[0050] In the preparation example 1-3, the glass fiber is selected from the glass fiber sold by Binzhou Anrun Chemical Fiber Rope Net Co., Ltd. with the article number AR-1116, and the graphene oxide is selected from the article number TF-12055 sold by Suzhou Carbonfeng Graphene Technology Co., Ltd. The graphene oxide and bisphenol A vinyl resin are selected from the bisphenol A vinyl resin sold by Changzhou Kainuosi Composite Material Co., Ltd. with the brand name VER-2.

preparation example 1

[0051] Preparation Example 1: (1) Burn the glass fiber in a muffle furnace at 600°C for 1.5 hours, and wash it twice with deionized water;

[0052] (2) Place the glass fibers in a dopamine solution with a concentration of 2 g / L and a pH value of 8.5, stir and react for 20 hours at room temperature, wash with deionized water for 3 times after filtration, and vacuum-dry at 65°C. The mass ratio of dopamine solution is 1:4;

Abstract

The invention discloses a PCM board for an elevator and a production process of the PCM board. The PCM board for the elevator comprises a finish paint layer, a primer layer, a passivation layer, a substrate, another passivation layer and another primer layer, wherein the finish paint layer, the primer layer, the passivation layer, the substrate, the passivation layer and the primer layer are sequentially arranged layer by layer; the finish paint layer comprises raw materials: castor oil modified waterborne polyurethane, modified glass fiber powder, propylene glycol methyl ether acetate, polyether modified organosiloxane, nano silicon dioxide, polytetrafluoroethylene, polytrifluorochloroethylene, a flatting agent, an anti-precipitating agent and a dispersing agent; and the primer layer comprises the raw materials: epoxy resin, modified basalt fiber, dibasic acid ester DBE, polyester modified organosiloxane, alkyd resin, polyethylene, precipitated barium sulfate, an anti-precipitating agent, a dispersing agent and a pigment. The PCM board for the elevator has the advantages that the tensile property of coating is good, and when the PCM is bent, a gap is not easily formed in the coating, so that the PCM board has the advantage of good salt fog resistance.

Description

technical field [0001] The invention relates to the technical field of color-coated boards, more specifically, it relates to a PCM board for elevators and a production process thereof. Background technique [0002] PCM board is a color-coated steel plate, which is mainly made of cold-rolled steel plate, electro-galvanized steel plate or hot-dip steel plate, after surface degreasing, phosphating, and complex salt treatment, and then roll-coating various organic coatings and baking. The product. It has the advantages of both steel plates and organic materials, not only the mechanical strength and easy-to-form performance of steel plates, but also the good decoration, corrosion resistance, and aesthetics of organic materials. It plays a role in substituting steel for wood, efficient construction, It has good effects such as saving energy, so it has become a new type of decorative material in the construction industry, shipbuilding industry, furniture industry, vehicle manufact...
