Abstract
The present invention is anticollision GRP sheath and its making process. Structurally, the anticollision GRP sheath is one hollow sheath comprising sheathing barrel and sheathing sides and with through hole, with the lower edge of the sheathing barrel being connected to the sheathing sides integrally. The anticollision GRP sheath is made of GRP, rubber or flexible plastic, and through the steps of making wooden mold, making blank to obtain semi-finished product and forming product. The anticollision GRP sheath has simple structure, convenient use, high sheathing, simple making process and other advantages.
Description
Technical field
The present invention relates to a kind of preparation method of glass fiber reinforced plastics anti-collision sheath.
Background technology
At present, iron and steel enterprise generally is to transport after day automobile-used its front fork directly pitches coil of strip when transhipment.Because this coil of strip is not taked safeguard procedures for exposed shape, so the front fork of overhead traveling crane damages contacted with it coil of strip volume face through regular meeting, thereby brings unnecessary economic loss to enterprise.
Summary of the invention
Technical matters to be solved by this invention is: a kind of simple in structure and glass fiber reinforced plastics anti-collision sheath of being convenient to make is provided, and this sheath can prevent coil of strip suffered injury when transport process.
The present invention solves its technical matters and adopts following technical scheme:
Glass fiber reinforced plastics anti-collision sheath provided by the invention is a hollow sheath, and it is made up of casing body and safe edge, and the lower end and the safe edge of casing body are connected as a single entity.
The method of the above-mentioned glass fiber reinforced plastics anti-collision sheath of preparation provided by the invention is: the formation step that comprises wooden die, blank, half product and product.
Glass fiber reinforced plastics anti-collision sheath provided by the invention has following main advantage:
The one, simple in structure, only form by casing and safe edge.
Two are to use conveniently, casing is inserted in the coil of strip center cavity of as ready after, can transport by transportation meanss such as overhead traveling cranes.
The 3rd, have protective action: because blocking of safe edge can prevent that the volume layer place of coil of strip end from being clashed into; Again because the obstruct of casing, the coil of strip center cavity inner face front fork of direct contact overhead traveling crane not like this, thus can avoid front fork to cause coil of strip to roll up the damage of face.
The 4th, technology is simple, is convenient to make.
Description of drawings
Fig. 1 is the structural representation of glass fiber reinforced plastics anti-collision sheath.
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
The invention will be further described below in conjunction with embodiment and accompanying drawing.
Anti-collision sheath of the present invention is a hollow structure, and as depicted in figs. 1 and 2: have through hole 3, be made up of casing body 1 and safe edge 2, the lower end of casing body 1 and safe edge 2 are connected as a single entity.
The longitudinal cross-section of described casing body 1 is an isosceles trapezoid.
The method of the above-mentioned anti-collision sheath of preparation provided by the invention is:
The preparation of glass fiber reinforced plastics anti-collision sheath comprises four steps of formation of wooden die, blank, half product and product.
1. preparation wooden die: earlier make blank wooden die with glass fiber reinforced plastics anti-collision sheath same structure shape, again its inwall and safe edge surface are used sand paper sand, go up polishing compound then and polish, as standby mould with timber.
2. the blank for preparing anti-collision sheath: waxing and last mold release on standby mould, brush paste resin again, the limit is pasted glass cloth sheet limit and is starched with the floating impregnated with resin that makes it of brush, and this is one deck; Repeat process just now, form the second layer; And the like, until the number of plies that pastes glass cloth of finishing designing requirement; Last curing agent forms blank after the natural seasoning, take off from standby mould.
3. half product of preparation anti-collision sheath: water coated abrasive working blank, and behind polishing, waxing and last mold release, paste resin on the limit again, the limit is sticked glass cloth sheet and is floating with brush, and this is one deck; Repeat process just now, form the second layer; And the like, the number of plies that pastes glass cloth until finishing designing requirement forms half product.
4. the product for preparing anti-collision sheath: water mill half product behind polishing, waxing and last mold release, with the burr of method of cutting out correction product, can form product again.
Count by weight, the composition of above-mentioned paste resin and content thereof are (seeing Table 1): resin 1.2～2, accelerator 0.04～0.055, pigment paste 0.07～0.085.
In the above-mentioned raw materials, polishing compound, waxing product can be with the product of U.S. Meguiar ' s company, under the situation of ensuring the quality of products, and the also product of available other company.Resin, pigment paste, accelerator, curing agent and mold release can adopt the product of Jiangsu Province's Changzhou China's Longhua worker's Co., Ltd or other company, and wherein, resin is 191 unsaturated polyesters, and accelerator is that different eo-acid bores, and curing agent is a methyl ethyl ketone peroxide.Pigment paste is mainly used in the painted of glass fiber reinforced plastics product, and its consumption can be adjusted the demand of color and luster according to the user.
