Abstract
The invention discloses a product of polyurethane-glass fiber resin compound material, which comprises a polyurethane foam layer and a glass fiber resin layer, wherein the glass fiber resin layer forms a hollow cavity, and the polyurethane foam layer is filled in the hollow cavity after the polyurethane is foamed by a chemical reaction. The preparation method comprises the following steps of: spraying a mold releasing agent in a mould of a prefabricated model; uniformly spraying the glass fiber resin on the inner surface of the mould, and forming the glass fiber resin layer provided with the hollow cavity after the glass fiber resin is cured; injecting a low-density polyurethane raw material in the mould, and foaming the polyurethane raw material by performing the chemical reaction to fill the polyurethane in the hollow cavity of the glass fiber resin layer to obtain the polyurethane foam layer; and after foaming formation, opening the mould to take the product out, and performing repairing and external spray-painting to complete the manufacturing. The product of the invention possesses dual-characteristics of hardness of glass steel as well as strength of low-density polyurethane inner core foam and is low in overall density and high in impact strength, so that the product wins wide markets.
Description
Technical field
The present invention relates to the building fittings adornment field, especially relate to urethane and glass fiber resin compound material product and manufacture method thereof.
Background technology
Polyurethane material is to be widely used in industry-by-industry, also be traditional formed materials such as architectural Rome commonly used column cap and ornament, urethane is divided into low-density polyurethane (150～250 kilograms per cubic meter) and high density polyurethane (300～500 kilograms per cubic meter) according to the density size.Resin then is toy, mould traditional materials such as product, artwork.
At present, FRP Columns goods and ornament on the market all are to be made by pure urethane material, about 300～500 kilograms per cubic meter of density, belong to high density polyurethane, be characterized in that density is big, the price height, but surperficial resistance to impact shock is low, is subjected to percussion damaged easily.
In view of having the defective that FRP Columns goods and ornament exist price height, cracky now, the inventor develops a kind of matrix material specially, and this case produces thus.
Summary of the invention
One of purpose of the present invention provides a kind of urethane and glass fiber resin compound material product, to reduce cost, improves the product shock resistance.
Two of purpose of the present invention provides a kind of method of making urethane and glass fiber resin compound material product.
In order to reach above-mentioned purpose, the present invention by the following technical solutions:
Urethane and glass fiber resin compound material product comprise polyurethane foam and glass fiber resin layer, and the glass fiber resin layer forms hollow cavity, and polyurethane foam is foam filled in hollow cavity through chemical reaction by urethane.
Further, the thickness of described glass fiber resin layer is 2～3mm.
Further, the blending ratio of resin and glass fibre is 100: 2 in the described glass fiber resin.
Further, described resin is a unsaturated polyester.
A kind of method of making urethane and glass fiber resin compound material product, its step is as follows:
The first step: in the mould of preset model, spray parting agent (claiming releasing agent again);
Second step: glass fiber resin be coated with equably be sprayed on the mould inner surface, wait glass fiber resin to solidify after, form glass fiber resin layer with hollow cavity;
The 3rd step: in the low-density polyurethane material injecting mould, foam, make the hollow cavity of urethane filled glass fiber resin layer, form polyurethane foam through chemical reaction;
The 4th step: after waiting foaming, product is taken out in die sinking, through studying for a second time courses one has flunked, spraying paint, finishes the processing and fabricating of whole prod outward again.
Further, described parting agent is a kind of organosilicon.
After adopting such scheme, the invention has the beneficial effects as follows: since with the strong fiber glass resin of rigidity height, hardness as product subsurface, with low density (150-250Kg/m
3) hard polyurethane foams fill as the product inner core, replace original high-density (300-500Kg/m thus
3) polyurethane products, reduce the raw-material consumption of urethane greatly, thereby reduced the cost of manufacturing product, has stronger supporting role again, so, product of the present invention not only has the hardness of glass fiber resin and polyurethane foam intensity, flexible double characteristic, and the product global density is low, impact strength good, and cost is also low.
Description of drawings
Fig. 1 is the structural representation of product of the present invention;
Fig. 2 is the process flow sheet of manufacture method of the present invention.
Embodiment
As shown in Figure 1, urethane and glass fiber resin compound material product that the present invention discloses comprise polyurethane foam 1 and glass fiber resin layer 2.
Glass fiber resin layer 2 constitutes the top layer of product (FRP Columns goods and ornament) and forms hollow cavity 21; The thickness of glass fiber resin layer 2 is 2～3mm, and glass fiber resin is the existing material of selling on the market, also can prepare voluntarily, and the blending ratio of resin and glass fibre is 100: 2; Resin is a unsaturated polyester.
Polyurethane foam 1 is foam filled in hollow cavity 21 through chemical reaction by urethane, constitutes the inner core of product.
The present invention makes the method for urethane and glass fiber resin compound material product, and as shown in Figure 2, step is as follows:
In the mould of preset model, spray parting agent (specifically be organosilicon, claim releasing agent again) earlier; With the resin of pre-designed set time, be added with corresponding glass fibre again, the mode with being coated with spray acts on the mould inner surface equably; After glass fiber resin curing, promptly constitute the top layer of product, form glass fiber resin layer 2 with hollow cavity 21; Then, in hard low-density polyurethane material injecting mould, urethane raw is chemical reaction under the effect of catalysis or temperature, and behind the foaming, the hollow cavity of urethane filled glass fiber resin layer forms polyurethane foam 1, promptly constitutes the inner core of product; Take out product at last, through studying for a second time courses one has flunked, spraying paint, finish the product processing and fabricating outward again.
The foregoing description products obtained therefrom not only has the hardness of glass reinforced plastic and polyurethane foam intensity, flexible double characteristic, and the product global density is low, impact strength good.
