Problems solved by technology

Generally, there are low-molecular impurities such as free phenol in the epoxy FRP composite material prepared by the traditional method. The free low-molecular impurity will reduce the high temperature resistance of the epoxy FRP composite material. The long-term service temperature of epoxy polyester FRP composite materials in the field usually does not exceed 120°C

Abstract

The invention relates to a formula of high-temperature resistant glass reinforced plastic, belonging to the technical field of glass reinforced plastic. The formula is characterized by comprising thefollowing components in percentage by weight: 30-40 parts of an unsaturated polyester resin, 10-30 parts of hydrogen peroxide, 1-3 parts of potassium oxide, 1-3 parts of phenol modified tungsten hexachloride, 1-5 parts of a flame retardant, 2-4 parts of a nano filler, 10-20 parts of glass fiber, 1-3 parts of a metal filler and 2-8 parts of an ultraviolet absorbent. The formula has the beneficial effects that the unsaturated polyester resin and other auxiliary materials are adopted as a curing system, glass fiber yarns are adopted as a reinforcing material, a high-performance composite linear material is produced, and due to a reasonable formula system, the strength of the product is improved; and due to adoption of the ultraviolet absorbent, the stability of the material is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastics, in particular to a high temperature resistant glass fiber reinforced plastic formula. Background technique [0002] Epoxy FRP composite materials are usually used in fields with high performance requirements, such as chemical industry, metallurgy and other fields. Traditional epoxy fiberglass composite materials usually mix epoxy resin with a certain proportion of ordinary phenolic resin as the body resin, and at the same time add some modifiers to the body resin to modify the body resin. Generally, there are low-molecular impurities such as free phenol in the epoxy FRP composite material prepared by the traditional method. The free low-molecular impurity will reduce the high temperature resistance of the epoxy FRP composite material. The long-term service temperature of epoxy polyester FRP composite materials in the field usually does not exceed 120 °C. Contents of the...
