Problems solved by technology

Due to the limited specifications of mass-produced FRP, multiple pieces are often required to be spliced ​​in practical applications; this requires the use of adhesives; however, the currently used adhesives generally cannot take into account the performance of transparent and light-stable sealants. not ideal
The adhesive strength is low, and it is easy to crack when soaked in water for a long time

Abstract

The invention belongs to the technical field of an adhesive, and concretely relates to a light stability sealant used for glass fiber reinforced plastic and a preparation method thereof. The light stability sealant comprises light stability sealant unsaturated polyester resin, cyclohexanone peroxide, cobaltous naphthenate, styrene paraffin liquid, octyldodecyl myristate, monoglyceride and triethanolamine according to a certain ratio; a unsaturated polyester resin acid value of the light stability sealant is 45 mg KOH / g, the viscosity is 69 pa.s, and the light stability sealant is specially prepared. The light stability sealant is transparent, and the adhesive property is good.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a light-stable sealant applied to FRP and a preparation method thereof. Background technique [0002] The scientific name of FRP is fiber reinforced plastic, commonly known as FRP (Fiber Reinforced Plastics), that is, fiber reinforced composite plastic. According to the fiber used, it is divided into glass fiber reinforced composite plastic (GFRP), carbon fiber reinforced composite plastic (CFRP), boron fiber reinforced composite plastic, etc. It is a composite material with glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as reinforcing material and synthetic resin as a matrix material. Fiber-reinforced composites are composed of reinforcing fibers and a matrix. The diameter of the fiber (or whisker) is very small, generally below 10 μm, with few and small defects, and the fracture strain is about 30 / 1000. It is a brittle material, easy to damag...
