Production process of glass fiber reinforced plastic paint

Abstract

The invention relates to a production process of glass fiber reinforced plastic paint, aiming at providing glass fiber reinforced plastic paint with high adhesion and a production process thereof. The technical scheme for realizing the aim of the invention is as follows: a process for preparing base stock of the glass fiber reinforced plastic paint comprises the following steps of: adding 10-15 parts by mass of epoxy resin and 10-15 parts by mass of dimethylbenzene into a reaction kettle, heating to 78-82 DEG C under the condition of stirring, stirring to be uniform, dropping 3-10 parts by mass of acrylic acid within 28-33 minutes, reacting for 2-2.5 hours, dropping a uniform mixture of 20-25 parts by mass of methyl methacrylate, 15-20 parts by mass of ethyl hexyl acrylate, 10-15 parts by mass of hydroxypropyl acrylate, 2-5 parts by mass of trimethylol propyl triacrylate, 10-15 parts by mass of styrene and 2-4 parts by mass of benzoyl peroxide into the reaction kettle within 50-60 minutes, and then reacting for 2-3 hours at the temperature of 78-82 DEG C to obtain the base stock of the glass fiber reinforced plastic paint. The production process provided by the invention is used for producing the glass fiber reinforced plastic paint.

Description

Technical field: [0001] The invention relates to a paint, in particular to a production process of a glass fiber reinforced plastic paint. Background technique: [0002] FRP materials are widely used due to their good weather resistance, light weight and certain mechanical strength. However, FRP products are heated and solidified in a mold. In order to facilitate demoulding, a release agent needs to be added to the resin. The release agent will be evenly transferred to the surface of the product after the product is released from the mold. At this time, if it is necessary to spray paint on the surface of the product, its adhesion will be poor. For example, the sound barriers on both sides of the road and the FRP anti-glare board in the middle of the road are all made of FRP. Due to poor adhesion, the paint layer often falls off, which affects the service life and appearance. Invention content: [0003] The purpose of the present invention is to provide a kind of FRP paint...

For example, the sound barriers on both sides of the road and the FRP anti-glare board in the middle of the road are all made of FRP. Due to the poor adhesion of the paint currently used, the paint layer often falls off, which affects the service life and appearance.
