Abstract
The invention is a method of making glass fibre reinforced plastic structure by build-forming, mainly winding glass fiber material on the foam core material, coating glass fibre reinforced plastic resin with fillings on the combination surfaces of many foam core material with glass fibers, adopting locating nail, clamp, and master form, etc, to locate, building into component blanks, and polishing the dried blanks and then splicing many blanks into a whole blank, again coating the glass fibre reinforced plastic resin on the surface of the whole blank, and pasting on glass cloth, drying and then polishing so as to obtain the finished products. It has simple making technique, and convenient to construct; can largely reduce cost and shorten production cycle, and has high specific strength of the whole structure; can act as both mould and material; reduces making cost of glass fibre reinforced plastic products. It simplifies producing technique, can produce large-scale glass fibre reinforced plastic products, and can implement field design and construction, etc.
Description
Technical field:
The present invention relates to a kind of manufacture method that belongs to the glass fibre reinforced plastic structure of building moulding by laying bricks or stones, belong to the glass-reinforced plastic material technical field.
Background technology:
Before the present invention makes, adopt glass-reinforced plastic material to make various glass fiber reinforced plastics products and in all conglomeraties, be used widely.The glass fibre reinforced plastic structure material, processing technology is as follows:
The detachable mould is generally adopted in the manufacturing of glass fiber reinforced plastics product, the manual pasting moulding.With model wooden, that gypsum is made goods, paste, polish mould according to model with materials such as resin, fiberglass then earlier.On mould, repeat to brush resin then by hand, paste glass fabric, felt, reach the regulation number of plies after, be polished to the glass fiber reinforced plastics product of multilayer after the drying.
The problem that adopts above-mentioned manufacture method to exist is: need use a large amount of moulds that need dismounting during the fiberglass moulding, need to be provided with supplementary structures such as a large amount of muscle, plate on the glass fiber reinforced plastics product structure with proof strength and rigidity.The fiberglass manufacturing cost height of this structure, number of molds is big, the production cycle is long.
Summary of the invention:
The objective of the invention is to overcome above-mentioned weak point, thereby provide a kind of manufacturing process simple, low cost of manufacture, with short production cycle, unit structure strength and stiffness height, the mould use amount is few, the manufacturing way of the glass fibre reinforced plastic structure of building moulding by laying bricks or stones of easy construction.
Main solution of the present invention is achieved in that its manufacture method is as follows:
(1). foamed material is cut into foam core material;
(2). on foam core material, twine glass fiber material;
(3). will twine the fiber glass resin of coating zone filler on the foam core material faying face of glass fiber material at least more than one; Build into fiberglass parts blank by laying bricks or stones; Adopt locating pin, clamping apparatus, pattern location.
(4). parts blank after drying adopts at least one block of fiberglass blank that above assembly unit is as a whole after modifying through polishing;
(5). on whole fiberglass blank surface, stick with paste fiber glass resin again, paste glass cloth, be finished product after the polishing of dry back is modified.
Among the present invention the band filler fiber glass resin in filler weight percentage be 5-50%; Wherein the talcum powder percentage by weight is that 0-25%, quartz sand percentage by weight are that 0-30%, staple glass fibre percentage by weight are that 1-15%, curing agent percentage by weight are 1-20%: the percentage by weight of fiber glass resin is 50-95%, talcum powder, quartz sand, staple glass fibre, curing agent and fiber glass resin are mixed in proportion, carry out at normal temperatures.
Glass fiber material among the present invention adopts glass fabric, glass mat, glass fiber mesh, glass fiber tape etc.
Fiber glass resin among the present invention adopts epoxy resin, polyurethane resin, phenolic resins etc.
Foamed material among the present invention generally adopts the last closed-cell materials of bubble.
The shape of the foam core material among the present invention is pressed the drawing design shape.
Curing agent among the present invention adopts ethylenediamine, triethylene tetramine, TEPA etc.
The following advantage that compared with the prior art the present invention has:
Manufacturing process of the present invention is simple, easy construction; Can save cost greatly, shorten the production cycle, owing to adopt the glass fibre reinforced plastics casing body, so the mode that tooled joint is built by laying bricks or stones is unit structure strength and stiffness height; The foamed material that is used for moulding is not removed, and is mould not only but also be moulding material; Omit a large amount of fiberglass moulds and made, thereby shortened the production cycle, reduced the manufacturing cost of glass fiber reinforced plastics product.Simplified production technology, can the production large-scale glass fibre reinforced plastic products, can also realize on-the-spot creation construction etc.
