Description
Technical field
The invention belongs to safety glass technical field, relate to the safety glass that a kind of fragmentation does not produce splash.
Background technology
Composite safe glass is just used to the windshield of automobile and the window of building from the thirties in last century.Safety glass normally to be bonded together through one or more layers intermediate coat by inorganic or lucite more than two panels or two panels and combines.When safety glass is subject to foreign object as stone hits, intermediate coat can play the effect of apparatus with shock absorbing and buffering, therefore safety glass has higher impact resistance relative to common single-glass, is widely used in multiple fields such as building, automobile, aircraft, high ferro and bulletproof glass.
For composite safe glass, structural glass mainly provides structural strength, in order to improve the method that security selects external structure glass to thicken usually, but so not only cause the significantly increase of part weight, very unfavorable for the vehicles, and a large amount of uses of material can be caused, cause the wasting of resources.
Summary of the invention
The object of the invention is the safety glass by designing a kind of new structure, improves its security performance while alleviating overall weight.Technical solution of the present invention is: this safety glass comprises two-layer transparent configuration material, centre is binded with one or more layers intermediate coat material, one deck splashproof safety diaphragm is pasted in the outside of transparent configuration material, this splashproof safety diaphragm is one deck composite construction film, composite construction film comprises three layers: layer of polyethylene butyral film or thermoplastic polyurethane or ethylene-vinyl acetate copolymer resin film are as bonding coat, additional one deck PETG, has one deck scratch resistance coating outside PETG.
Described transparent configuration material can be the one or more combination in tempering or half tempered unorganic glass, lucite, polycarbonate transparent material.
The thickness of transparent configuration material can be 2-20mm, and preferred thickness is 2-5mm.
Intermediate coat material can select polyvinyl butyral film, one or more in thermoplastic polyurethane or ethylene-vinyl acetate copolymer resin film.
The thickness of intermediate coat material can be 0.5-2mm, and optimum thickness is 0.7-1.5mm.
The thickness of bonding coat is 0.2-1mm, preferred 0.35-0.8mm, the thickness 0.05-0.5mm of PETG, preferred 0.1-0.3mm, PETG outer surface hard anti-scratch coating is the organic clear coat containing nano silicon oxide or zirconia particles, and coating hardness is 2-4H.
The present invention devises the safety glass that a kind of new structure has tight security, improves its security mainly through adding the safe antispray layer of one deck inside common safety glass.The advantage that the present invention has and beneficial effect, the present invention structurally adds one deck splashproof safety diaphragm relative to common safety glass, and security improves greatly.This is because splashproof safety diaphragm has the effect of certain supplementary enhancing for safety glass on the one hand, the impact strength of safety glass effectively can be improved on to a certain degree; On the other hand because splashproof safety diaphragm used has very high tearing strength and elongation at break, the fragment after structural bearing material fragmentation can be stoped to enter harm people body in cabin, effectively improve the security performance of safety glass.Like this, to the thickness that suitably can reduce external structure loading material in the structural design of safety glass, play loss of weight, reduce costs and do not reduce the ideal effect of security.This structure has broad application prospects in the field of vehicles such as aircraft, high ferro, automobile.
