Low-temperature-resistant glass fiber reinforced plastic pultrusion profile and preparation method thereof

Abstract

The invention discloses a low-temperature-resistant glass fiber reinforced plastic pultrusion profile and a preparation method thereof, and relates to the technical field of glass fiber reinforced plastic pultrusion profiles. The pultrusion profile comprises the following raw materials: 15-18% of unsaturated polyester resin, 18-20% of polytetrafluoroethylene resin, 6-7% of thermosetting methacrylic resin, 9-10% of epoxy resin, 5-6% of flame-retardant vinyl resin, 4-5% of an anti-ultraviolet agent, 15-16% of a glass fiber mat, 9-10% of basalt fibers, 2.5-3% of an initiator, 3-4% of an epoxy resin curing agent, 3.5-4% of a coloring agent, 2.5-3% of an internal release agent, 1.5-2% of a flame retardant and 3.5-4% of a coupling agent. According to the low-temperature-resistant glass fiber reinforced plastic pultrusion profile and the preparation method thereof, the low-temperature-resistant glass fiber reinforced plastic pultrusion profile has good low-temperature-resistant and high-temperature-resistant effects, and the actual use range is greatly widened; by adding the polytetrafluoroethylene resin, the profile can be used at the low temperature of (-160)-(-200) DEG C, and use in a special environment is met; and the anti-ultraviolet agent is blended, so that the low-temperature-resistant glass fiber reinforced plastic pultrusion profile has a very good anti-oxidation effect.

Description

technical field [0001] The invention relates to the technical field of FRP pultrusion profiles, in particular to a low-temperature-resistant FRP pultrusion profile and a preparation method thereof. Background technique [0002] The scientific name of FRP pultrusion profile is glass fiber reinforced plastic, commonly known as FRP (Fiber Reinforced Plastics, fiber reinforced composite plastic), which uses glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as a reinforcing material and synthetic resin as a matrix A composite of materials. According to the fiber used, it is divided into glass fiber reinforced composite plastic (GFRP), carbon fiber reinforced composite plastic (CFRP) and boron fiber reinforced composite plastic. [0003] The existing FRP pultruded profiles have poor low temperature resistance and cannot be used in special environments. At the same time, the preparation process of FRP pultruded profiles is relatively cumbersome, resulting in low p...

Problems solved by technology

[0003] The existing FRP pultruded profiles have poor low temperature resistance and cannot be used in special environments. At the same time, the preparation process of FRP pultruded profiles is relatively cumbersome, resulting in low production efficiency of FRP pultruded profiles. Therefore, we propose Such low temperature resistant FRP pultrusion profile and preparation method thereof
