Abstract
What the present invention relates to is a kind of high-strength compounded glass fibre reinforced plastic and preparation method thereof.
Fiberglass of the present invention adopts synthetic resin, chlorine oxygen magnesium adhesive, or use polyethylene, polyvinyl chloride etc. are done superficial layer or composite bed raw material, and accompany cullet or blinding in the middle of the main matrix material of two-layer or multilayer, or the intermediary layer of quartz sand raw material, through batching, clear mould, superficial layer, intermediary layer, composite bed is manufactured, cure and demold, and technologies such as drying are composited.
Method of the present invention is simple, and cost is low, gives full play to the advantage of multiple synthetic resin, makes glass fiber reinforced plastics product can have the performance of multiple material concurrently, allows glass fiber reinforced plastics product more be tending towards perfect.
Description
What the present invention relates to is high-strength compounded glass fibre reinforced plastic of using in fields such as medicine, health, chemical industry, building materials, industrial art and preparation method thereof.
Fiberglass industry production technology always is on a glass fiber reinforced plastics product both at home and abroad, and adopting a kind of adhesive made of synthetic resin is that main matrix material and a kind of reinforcing material are made.Since goods be subjected to single synthetic resin matrix raw material on performance, the restriction of the aspects such as cost of processing technology, raw material, limited the range of application of glass fiber reinforced plastics product to a great extent, also be difficult to adapt to the needs in market.For example: the antiseptic effect of fiber glass epoxy is better, but cost is higher, and the user is difficult for accepting; Unsaturated polyester resin fiberglass cost is low, but antiseptic effect is again not as fiber glass epoxy; The phenolic fiberglass reinforced plastics alkali resistance is better, but property is crisp, intensity is low, poor mechanical property; Chlorine oxygen magnesium FRIM cost is low, and rigidity is good, but quality is heavy; So be used alone the fibre glass product manufacture that synthetic resin matrix raw material is made, be not satisfy the user to the many-side requirement of goods.
The deficiency that the glass fiber reinforced plastics product of producing at prior art exists on technical performance, the objective of the invention is, fully utilize various matrix materials, on a glass fiber reinforced plastics product, adopt two or more adhesive made of synthetic resin and multiple reinforcing material, give full play to and utilize the advantage of multiple matrix material, prepare a kind of fiberglass of high-strength compound, make glass fiber reinforced plastics product can have metal concurrently, pottery, plastics, the performance of multiple material such as timber, simultaneously the cost of glass fiber reinforced plastics product is significantly reduced, and can enlarge the range of application of fiberglass, with the demand of the glass fiber reinforced plastics product that satisfies different clients.
The main points of high-strength compounded glass fibre reinforced plastic of the present invention and preparation method thereof are, utilize a kind of intermediateness " binding agent ", promptly in the middle of two kinds of different fiberglass adhesive made of synthetic resin, an intermediary layer is set, by this intermediary layer, the synthetic resin that makes two or more is that main matrix material is combined as a whole securely.
High-strength compounded glass fibre reinforced plastic of the present invention, adopt unsaturated polyester resin, phenolic resins, epoxy resin, Lauxite, furane resins or chlorine oxygen magnesium adhesive to do the main matrix material of superficial layer or composite bed, perhaps make the raw material of superficial layer of polyethylene, polyvinyl chloride, and at superficial layer raw material and composite bed raw material, or middle intermediary layer raw material cullet or blinding or the quartz sand of accompanying of the raw material of multilayer, through batching, clear mould, superficial layer is manufactured, intermediary layer is manufactured, composite bed is manufactured, cure and demold, and technical process such as drying are composited.
For high-strength compounded glass fibre reinforced plastic of the present invention and preparation method thereof there being further understanding, in conjunction with concrete prescription of the present invention, process and embodiment, enumeration is as follows:
