Abstract
A car body made of glass fiber reinforced plastic is disclosed. Its repairing process includes such steps as grinding on the damaged position, coating resin adhesive, drying in air, alternatively coating the talc powder-resin adhesive and sticking glass fiber fabric until its height is 1-2 mm greater than peripheral height, solidifying, grinding for smoothing, coating unsaturated polyester putty, drying in air, abrasing and spraying color paint.
Description
Technical field the invention belongs to the auto repair technical field, relates to the method for repairing and mending of a kind of fiberglass car body and components damage thereof.
Background technology is present, and the passenger car body shell generally is made of the fiberglass material, because of clashing into the damage that all can be subjected in various degree.For the lighter position of damage, all use sheet iron and rivet that breakage is carried out riveted and fixed at its back side, Puttying in the above then, the moulding of after polishing, spraying paint again.The method for repairing and mending of prior art, neither attractive in appearance not firm yet, through after a while use, jolt, can be out of shape, come off; For serious car body or the parts of some damage, prior art can't be repaired at all, can only abandon trade-in, causes very big waste, and since the fiberglass waste product can not recycle, can only be as rubbish, thus cause environmental pollution.
Summary of the invention the purpose of this invention is to provide a kind of method for repairing and mending that can recover robust again fiberglass car body of car body former state and components damage thereof, to overcome the deficiencies in the prior art.
The method for repairing and mending of fiberglass car body of the present invention and components damage thereof, its main points are finished according to following step: at first polish at injury region, at the burnishing part glue of resinizing, powder coating resin glue again after drying is coated with one deck talcum powder resin sticker layer of glass cloth until exceeding about periphery 1～2mm, after waiting to solidify, polish flat, scrape unsaturated polyester (UP) putty at mend, treat that putty solidifies the back and polishes smooth with silicon carbide paper, get final product according to mend primary colors paint spraying then.
Said resin glue is to be made by the weight proportion of 100:4:4 by unsaturated polyester resin, peroxide MEK and cobalt octoate.
Said talcum powder resin glue is to be made by the weight proportion of 100:10 by above-mentioned resin glue and talcum powder.
Technology of the present invention is simple, easy operating, and through patched glass car body position and parts thereof, it is repaired, and the face adhesion is strong, indeformable, shock-resistant, nothing is repaired vestige, it is low to repair cost, is a kind of desirable fiberglass car body and the method for repairing and mending of components damage thereof.
The specific embodiment:
Embodiment 1, golden imperial passenger vehicle front bumper are repaired by following step method because of the bump fracture:
(1), with fracture place section crops for rotation to good, with hand grinding tool that the positive mill of fracture place is recessed, the degree of depth is 1/2 of a mend thickness, middle dark, periphery is shallow, becomes the transition type inclined-plane.In order to strengthen robustness, the inclined-plane that grinds should be greater than crack periphery 4-5 centimetre;
(2), the size long-pending according to institute's flour milling, glass fabric has been cut out standby;
(3), unsaturated polyester resin, methyl ethyl ketone peroxide and cobalt octoate are made resin glue by the weight proportion of 100:4:4, with hairbrush uniformly brush on the hair side that grinds;
(4), spend 10 minutes and dry after, get above-mentioned resin glue and add talcum powder again and make the talcum powder resin glue by the weight proportion of 100:10, be coated with one deck talcum powder resin sticker layer of glass cloth until exceeding about peripheral 1mm, so that polishing;
(5), solidify after, with reverse side fracture place of bumper, connect positive patching and repair;
(6), treat that reverse side solidifies after, the front mend with bumper polishes with hand grinding tool;
(7), on mend is scraped unsaturated polyester (UP) putty, wait putty to do after, the silicon carbide paper with 180#, 400#, 600# polishes smooth mend putty successively;
(8), the color paint original according to mend, spray and get final product.
Embodiment 2, golden imperial passenger vehicle rear bumper cause the left side incomplete because of bump, according to embodiment 1, repair by following step method:
(1), with incompleteness place section, wear into the inclined-plane with hand grinding tool, wide 5-6 centimetre;
(2), copy the shape at position, right side, do a simple and easy supporting mould with sheet iron, mould is fixed on the back side at incomplete place;
(3), brush liquid wax in die face, so that the demoulding;
(4), with resin glue with hairbrush brush on mould, resin glue is full of on the inclined-plane at breakage edge uniformly;
(5), by incomplete area size, it is standby to have cut out glass fabric;
(6), use the talcum powder resin glue, with hairbrush sticking on the mould in layer, glass fabric is contacted fully with the damaged inclined-plane that grinds glass fabric, recover original moulding until incomplete position;
(7), solidify after, remove mould, mend is repaired ground smooth with hand grinding tool;
(8), on mend is scraped unsaturated polyester (UP) putty, treat that putty is done after, polish smooth with the silicon carbide paper of 180#, 400#, 600# putty successively mend;
(9), the color paint original according to mend, spray and get final product.
Implement reason 3, rear taillight position, palace car Volvo left side because of clashing into fragmentation,, repair by following step method according to embodiment 1:
(1), the fragmentation place back side is pasted firmly the typing location with wide adhesive tape;
(2), according to the linear and angle rib at broken place on the car body, use the mould sanding, the hair side that grinds should be greater than damage surface;
(3), according to the moulding of long-pending size of institute's flour milling and injury region, cut out thin glass fiber cloth standby;
(4), resin glue is brushed on the hair side that grinds uniformly with hairbrush;
(5), spend 10 minutes after, use the talcum powder resin glue again, glass fabric with hairbrush sticking on the hair side that grinds in layer, is solidified until recovering moulding, wait for;
(6) solidify after, with electric mill with mend along with moulding is repaired;
