Problems solved by technology

But also there are some problems in the production of FRP profiles, one of them is exactly the monotonous profile color of production, when needing other colors, can only brush or spray paint, as just disclosed a kind of adopting electrostatic spraying to produce FRP in CN1361194A profile method
However, the method of spraying paint will complicate the subsequent processes, such as the process of sanding, puttying and painting in the door and window assembly process; and the quality of the sprayed paint is not uniform enough, and there are some deficiencies in wear resistance

Abstract

The invention relates to a resin mixture used for producing FRP (fiberglass-reinforced plastics) profile, the FRP profile made from the mixture and a preparation method thereof. The resin mixture comprises the following materials according to weight proportion: 10 of resin, 0.4 to 3 of low shrinkage agent, 2 to 15 of fillers, 0.05 to 0.2 of low temperature curing agent, 0.05 to 0.2 of high temperature curing agent, 0.05 to 0.2 of parting agent, 0.02 to 0.5 of pigment and appropriate amount of coupling agent and ultraviolet absorbent. The preparation method of the FRP profile by using the mixture is that: a reinforcing material is immersed into the resin mixture. The obtained material is extruded to get forming under high temperature and high pressure through a die; during the extrusion forming, the die is heated after being separated into three segments, and the temperature of the three segments is respectively 60 DEG C to 100 DEG C of a first segment, 100 DEG C to 150 DEG C of a second segment, 100 DEG C to 148 DEG C of a third segment; the haulage speed is 320 mm/min.

Description

technical field [0001] The invention relates to the production of FRP profiles, in particular to a resin mixture for producing FRP profiles, a FRP profile prepared by the mixture and a method thereof. Background technique [0002] FRP profiles are commonly used materials for the production of doors and windows. The doors and windows made of FRP profiles not only have the sturdiness of steel and aluminum doors and windows, but also have the anti-corrosion, heat preservation, and energy-saving properties of plastic-steel doors and windows, and have their own unique properties. No expansion under direct sunlight, no shrinkage in cold climates, light weight and high strength, no need for metal reinforcement, aging resistance, long service life, and its comprehensive performance is superior to other types of doors and windows. [0003] At present, there are existing methods for producing FRP profiles. For example, CN1789331A discloses a preparation method for antibacterial FRP pr...
