Description
Technical field
The invention belongs to fiber glass resin field, it is specifically related to a kind of steel of resistance to uviol pultrusion resin and its preparation side
Method.
Background technique
Glass fiber compound material, that is, glass reinforced plastic refers generally to glass fiber reinforcement unsaturated polyester, epoxy resin and phenol
Urea formaldehyde matrix.Make the reinforced plastics of reinforcing material with glass fibre or its product, appellation is fiberglass reinforced plastics, or
Glass reinforced plastic is called, pays attention to being distinguished with tempered glass.Since used resin variety is different, there are organic toughened glass, ring
The title of oxygen glass reinforced plastic, phenolic fiberglass reinforced plastics.Light and hard, non-conductive, performance stablizes high mechanical strength, recycles few, corrosion resistant
Erosion.It can replace steel manufacture machine part and automobile, ship housing etc..Glass reinforced plastic alias fiberglass reinforced plastics, is commonly called as
FRP (Fiber Reinforced Plastics), i.e. fibre-reinforced plastics.It is divided into glass according to the fiber difference of use
Fibre-reinforced plastics (GFRP), fibre reinforced composite plastic (CFRP), boron fibre enhance composite plastic etc..It is with glass
Glass fiber and its products (glass cloth, band, felt, yarn etc.) are used as reinforcing material, compound with one kind that synthetic resin makees basis material
Material.Fibre reinforced composites are made of reinforcing fiber and matrix.The diameter very little of fiber (or whisker), generally at 10 μm
Hereinafter, defect is less and smaller, breaking strain be about within 30/1000ths be fragile material, easy damaged, fracture and by corruption
Erosion.For matrix for fiber, intensity, modulus will be much lower, but can withstand big strain, often have viscoplasticity
And elastoplasticity, it is toughness material.
Glass fibre reinforced composion has been widely used because of characteristics such as its specific strength is high, corrosion-resistant, light weights in building
It builds, the various fields such as automobile, the energy, electronics, the effect of loss of weight is not only acted as on the basis of meeting intensity requirement also very big
Economic cost is reduced in degree.The drawing more demanding, traditional for uvioresistant performance of the product in outdoor application to material
Extrusion forming glass fiber reinforced plastics composite material UV resistance is general, is chronically exposed under illumination condition and is easy to produce aging phenomenon, intensity
It all can be by serious influence with appearance.
