Problems solved by technology

[0003] The general pultrusion speed of FRP pultrusion production line is 500mm / min~1000mm / min, but the conventional pultrusion speed is too low to meet the high speed and high quality of modern pultrusion technology, so it is necessary to use unsaturated resin fast curing formula, through adjustment The ratio of the resin and its curing system enables it to achieve rapid curing molding, improve the yield rate of the product and increase the pultrusion speed to achieve rapid mass production. For this reason, we propose a FRP pultrusion unsaturated resin rapid curing formula manufacturing process

Abstract

The invention discloses a manufacturing process of a glassfiber reinforced plastic pultrusion unsaturated resin rapid curing formula. An unsaturated resin curing agent is prepared from the following components in percentage by weight: 100% of resin (191#), 0.5-1.5% of a curing agent (dibenzoyl peroxide), 0.5-1.5% of a catalyst (dodecylthiol), 0.5-1.5% of an initiator (N.N-dimethyl-p-toluidine), 25-40% of a filler (calcium carbonate and aluminum hydroxide), 0.5-0.8% of an anti-cracking agent (liquid nitrile rubber and polyvinyl butyral), 0.5-0.8% of a brightener (titanium dioxide), 0.5-0.8% ofan anti-ultraviolet agent (JADEWIN UV 320), 0.2-0.6% of a flame retardant (magnesium hydroxide and red phosphorus), 0.1-0.3% of color paste and 0.5-1.5% of pigment. Compared with other process technologies, the technology is low in cost, the process is mature, by adjusting the ratio of resin to a resin curing system, the resin is subjected to rapid curing molding, and the yield of products and thepultrusion speed are increased to achieve rapid mass production.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastics production, and more specifically relates to a manufacturing process of a glass fiber reinforced plastics pultrusion unsaturated resin rapid curing formula. Background technique [0002] In the FRP pultrusion industry, reinforced materials such as continuous rovings and felts soaked in glue are solidified and formed by heated metal molds under the action of traction to continuously produce products. [0003] The general pultrusion speed of FRP pultrusion production line is 500mm / min~1000mm / min, but the conventional pultrusion speed is too low to meet the high speed and high quality of modern pultrusion technology, so it is necessary to use unsaturated resin fast curing formula, through adjustment The ratio of the resin and its curing system enables it to achieve rapid curing molding, improve the yield rate of the product and increase the pultrusion speed to achieve rapid ma...
