Description
The present invention relates to a kind of manufacture method of safety glass, mainly be after becoming transparent glue pellet with mixed raw materials such as polyurethane (PU), acrylic (Acrylic) and epoxy resin, glue pellet is folded between the superimposed interlayer of each tempered glass and PC or PET material, this is inserted in the vacuum high-pressure boiler do to increase progressively pressurization, successively decrease again and take out after the step-down, promptly make safety glass.
Safety glass is a kind of material that is widely used in automotive window or house window, the intensive treatment of its structure of mat, making it to have security effectivenesses such as shellproof, explosion-resistance characteristic, to safeguard the safety of the person or property, wherein is again main application of safety glass and market with the automotive window.
The manufacturing of conventional security glass mainly is with the several layers of stacked bonding composition of tempered glass.Adding up of the reinforced structure of mat number layer glass with complementary, and then can improve whole structural strength, reach shellproof, explosion-proof usefulness.But from the textural association form, adopt the several layers of structure that tempered glass is stacked, just cause the increase of weight between invisible, and because it is the master that is applied as with automotive window, the automotive window mechanism for opening/closing only is to design at general glass as another, therefore the increase of its weight is just to forming great load in order to the mechanism that opens and closes vehicle window, even cause vehicle window normally lifting open and close, and must otherwise designed be suitable for mechanism, not only form outside the trouble and expense of repacking, its amplitude that can open is still restricted, cause common people not high for the interest of automotive window repacking safety glass, even what look is the dangerous road, has a strong impact on the market expansion of safety glass, quite unfortunate really.
For improving conventional security glass fully by the superimposed weight issue that produces of tempered glass, someone improves to reducing the number of plies and replacing direction such as partial reinforment glass with other material, and then develops the safety glass that with tempered glass collocation Merlon (PC) or the stacked composition of polyester (PET) material.Utilize the transparency of PC or PET material to replace the tempered glass of internal layer, and the toughness of mat material and elasticity and can appropriateness improve whole resistance to impact.Especially these PC or PET material is in light weight, for the overall weight that alleviates safety glass obvious help will be arranged, so the safety glass of this kind composite just becomes the market mainstream gradually.
But with regard to this type of composite formula safety glass of forming with tempered glass collocation PC or PET material, though have the advantage that alleviates the safety glass overall weight, yet these two kinds of materials but have very important common drawback, the wearability that is its material is on duty mutually, so with the friction of press strip, perhaps the grit friction during the wiping vehicle window all is easy to cause the generation of its surperficial scratch between the repetitiousness lifting on-off action of vehicle window, and these scratches will have great influence to its perspectivity.Thereby for protecting this PC or pet layer to produce to prevent scratch; usually adopt folder to cover the manufacturing of formula structure; PC or PET material are interposed between two-layer tempered glass to constitute the safety glass structure; in appropriate weight reduction and possess outside the advantage of resistance to impact, can also have concurrently and prevent that scratch from keeping preferable perspectivity like this.
Yet, but this kind safety glass faces another serious problems, promptly when tempered glass and PC or PET material are combined into one, must be glued together by the higher viscose glue of mat viscosity, and this kind viscose glue is because of having higher viscosity, the perspectivity of itself is just poor, add and be difficult for smoothening, after gummed is done admittedly, influence its perspectivity unavoidably, especially under the accumulation result of multilayer viscose glue, its whole perspectivity is poorer, not only cause sight line unclear with discomfort outside, more be an impediment to traffic safety, in fact remain to be solved improvement.
In view of this, promptly how at tempered glass with PC or the PET material is stacked combines and obtain best perspectivity, become important topic extremely to be solved at present.
For this reason, the object of the invention provides a kind of manufacture method of safety glass, it mainly is with polyurethane (PU), after mixed raw materials such as acrylic (methacrylic acid or methyl methacrylate) and epoxy resin become transparent glue pellet, glue pellet is folded between the superimposed interlayer of each tempered glass and PC or PET material, this is inserted in the vacuum high-pressure boiler do to increase progressively pressurization, take out after the step-down of successively decreasing again, promptly make strong bonded all-in-one-piece safety glass.Owing to utilize high pressure effect and glue pellet material characteristic can obtain the firm adhesion and the definition of high perspectivity.
