Embodiment Construction

[0009] A surface treatment method for FRP products, mainly comprising the following steps:

[0010] a. After the FRP product is molded and molded, a layer of particles is sprayed on the surface of the gel coat layer;

[0011] b. Spray primer on the particle layer;

[0012] c. Spray topcoat on the primer to get the product.

[0013] The gel coat layer is selected from an easy-to-grind gel coat, which has good leveling properties and is easy to polish, which ensures the effect of sandblasting. Focus on.

[0014] The particle layer is a quartz sand layer, and the mesh number of the quartz sand is 400-500 mesh. The mesh number of quartz sand should be appropriate, if the mesh number is too high, the surface roughness of the product is not enough, and the adhesion with the paint cannot be guaranteed; if the mesh number is too low, it is easy to cause damage to the surface of the product. When sandblasting, use a special sandblasting machine, and the sandblasting force is unifor...

Abstract

The invention belongs to the field of glass fiber-reinforced plastics, and in particular relates to a surface treatment method for a glass fiber-reinforced plastic product. The scheme mainly comprises the following steps of: forming and demoulding the glass fiber-reinforced plastic product; spraying a particle layer on the surface of a gel coat layer; spraying a base paint on the particle layer; and spraying a finish paint on the base paint to obtain the finished product. Through the technical scheme, the glass fiber-reinforced plastic product is basically polish-free, the manufacturing efficiency of the product is high, the production cost and the environmental pollution are reduced, the painting effect of the surface of the glass fiber-reinforced plastic product is improved, and the paint has excellent adhesion with a substrate.

Description

technical field [0001] The invention belongs to the field of glass fiber reinforced plastics, and in particular relates to a surface treatment method of glass fiber reinforced plastic products. Background technique [0002] At present, in the field of FRP, the surface of most FRP products is painted. First, the surface of the gel coat layer must be polished two to three times to meet the surface roughness requirements of spray paint before spraying paint. However, the grinding of the gel coat surface of FRP not only wastes a lot of manpower and material resources, but also causes serious pollution to the environment. Contents of the invention [0003] The purpose of the present invention is to provide a surface treatment method for FRP products, which can meet the surface roughness requirements of spray painting without grinding. [0004] In order to achieve the above object, the present invention adopts the following technical solutions, a surface treatment method for FR...
