Abstract
The utility model discloses a resin transferring molding compound sandwich glass fiber reinforced plastic product, which belongs to the glass fiber reinforced plastic product of a vehicle. The structure is characterized in that after an outer surface adopting polyurethane foam as core material is wrapped with a glass fiber fabric, the utility model is arranged in a sealing film sprayed with a gel coat layer and after polyester resin mixture is poured, the utility model is solidified into a compound clamping core of glass fiber reinforced plastic. The utility model has smooth surface, beautiful model, light weight and high strength. The utility model can be used for automotive industries, building trades and electric fields.
Description
The utility model belongs to the vehicle glass steel part, particularly a kind of multi-purpose high-intensity resin transfer moulding compound sandwich glass fiber reinforced plastics products such as automobile empennage, speed change train panel, electric product that are used for.
The vehicle glass steel part of past usefulness mostly is hand and sticks with paste glass fiber reinforced plastics product, adopts hollow to mode structure, and product is yielding, and rigidity and apparent property are lower, the moulding process complicated operation, and artificial investment is bigger, and machining accuracy is difficult to guarantee.
The purpose of this utility model provide a kind ofly have the excellent appearance performance, briquetting pressure is little, light weight, high-intensity resin transfer moulding compound sandwich glass fiber reinforced plastics product.
The purpose of this utility model is achieved like this: a kind of resin transfer moulding compound sandwich glass fiber reinforced plastics product, it is characterized in that: at first make foam core body 1, secondly at cavity surface spraying gel coating resin 2, then the foam core body 1 of coated outside glass fabric is put into die cavity, matched moulds perfusion polyester resin mixture, curing molding is a frp layer 3.
Described sandwich material is a polyurethane foam, phenol formaldehyde foam, a kind of in the materials such as cork, honeycomb.The used polyurethane foam of the utility model is that cast under low pressure formed after A, B two components were mixed in proportion.
Described frp layer is by warm 50-70 ℃ curing molding in polyester resin mixture and the glass fabric warp.
Described polyester resin mixture is 670
#The promoter cobalt naphthenate of adding 1-4% and an amount of compositions such as LPA-1 low shrinkage additive, dispersant, defoamer and filler mix in the mylar.
The utility model is compared with prior art: adopt the compound sandwich glass fiber reinforced plastics product proportion of resin transfer molding little, light weight, the intensity height, ornamental strong, processability is good, but one-shot forming, briquetting pressure is little, the cost cost is low, can be used for automobile glass spoiler, empennage and fields such as building structure goods, electric housing thereof, and the market using value is big.
Below in conjunction with description of drawings the utility model is illustrated.
Fig. 1 is a resin transfer moulding compound sandwich glass fiber reinforced plastics product automobile empennage schematic diagram.
Fig. 2 is the AA cutaway view of Fig. 1.
Embodiment:
By as can be known shown in Figure 1, the utility model is the automobile empennage schematic diagram of one of resin transfer moulding compound sandwich glass fiber reinforced plastics product, its material structure as shown in Figure 2, after the outside of the sandwich body 1 of polyurethane foam is wrapped the layer of glass fabric earlier, packing into is coated with in the closed die cavity of gel coating resin 2, from the injection port perfusion of reserving 670
#Polyester resin mixture through vacuum assisted resin infusion, heats 50-70 ℃ of intermediate temperature setting and becomes frp layer 3, becomes resin transfer moulding compound sandwich glass fiber reinforced plastics product after the demoulding.Carry out secondary operations again, promptly be made for the good high-intensity compound sandwich glass fiber reinforced plastics product of apparent mass, the materials processing performance of the utility model resin transfer moulding compound sandwich glass fiber reinforced plastics product is fine, just energy moulding of 1-1.5bar under low pressure, saved the great amount of manpower and material resources investment, goods possess the face shaping of bright and clean grace, light weight, the intensity height can use in fields such as building decoration, automobile industry, electric utilities.
