Problems solved by technology

[0002] The matrix resins used in traditional composite pultrusion products are thermosetting resins such as epoxy resin and unsaturated polyester. Therefore, these composite products require high temperature heating during curing. The general curing temperature is between 160°C and 180°C. High energy consumption, long curing time, pultrusion speed is usually about 2m / min, low production efficiency, in addition, some organic solvents added in the traditional matrix material system will volatilize into the air during curing, causing pollution to the environment

Abstract

The invention relates to a photothermal double-cured resin composition for pultrusion and a glass fiber composite material prepared from the photothermal double-cured resin composition, and belongs tothe technical field of polymer materials. The composition is composed of the following components: in parts by mass, 60-75 parts of epoxy acrylate, 25-40 parts of a reactive diluent, 4-10 parts of aphotoinitiator, 1-4 parts of a thermal initiator, 1-3 parts of a thickener, 0.5-1 part of a silane coupling agent, 0.5-1 part of a defoamer, 0.5-1 part of a polymerization inhibitor and 0.5-1 part ofan internal releasing agent. The glass fiber composite materials which is prepared from the composition has high hardness, high tensile strength, high flexural strength and high flexural modulus; moreover, photothermal double curing is adopted, the curing depth is good, and the pultrusion speed can be increased to 5-10 m / min; and only initial molding of the material is achieved through thermal curing, no complete curing is needed, and therefore only a temperature of 80-100 DEG C is needed, so that energy consumption is greatly reduced.
