Abstract

The utility model discloses laminated glass which comprises two glass main bodies (1) and a PVB (Polyvinyl Butyral) film (2) arranged between the two glass main bodies, wherein the PVB film (2) which is a PVB heat isolating film treated by heat isolating nano antimony-doped tin oxide or heat isolating nano tin-doped indium oxide binds and fixes the two glass main bodies (1). According to the laminated glass, the prepared laminated glass has better capacity of resisting external impact through treatment by heat isolating nano antimony-doped tin oxide or heat isolating nano tin-doped indium oxide on the common PVB film, so that the anti-theft, soundproof and ultraviolet-proof performances are improved.

Description

A kind of doubling glass

Technical field

The utility model relates to energy-saving glass technical field, more particularly, relates to a kind of doubling glass.

Background technology

Doubling glass is tough and tensile polyvinyl butyral acetal (PVB) intermediate coat on folder between two-layer or multiple glazing, through High Temperature High Pressure, is processed into.PVB film has good cohesiveness, toughness and elasticity, at laminated glass, be subject to that external force clashes and when broken, this tunic can absorb large energy, glass fragment can firmly stick on PVB intermediate coat, glass fragment can not disperse, thereby issuable injury is reduced to a minimum.Laminated glass has good security, noise reduction, controls sunlight characteristic and antiultraviolet feature.Can select as required simple glass, toughened glass, LOW-E glass as former, thereby make laminated glass there is different premium propertiess.This shatter proof glass is widely used in the fields such as automobile, Highrise buildings, aviation, navigation.When thering is security feature, also have excellent sound insulation, light-operated, insulation, the performance such as heat insulation, antifog, be ideal shatter proof glass work material.

In automobile industry, PVB film is the main raw of manufacturing windshield.Due to laminated safety glass, there is the multiple functions such as safety, insulation, control noise and isolation ultraviolet ray, so be also widely used in fields such as buildings.As building curtain wall, door and window, lighting ceiling, skylight, furred ceiling, ground spacing, large-area glass body of wall, glass furniture, indoor glass partition, shopper window, sales counter, water bunch shop, bank counter, prison control form, steel melting furnace screen window and various splinter-proof glasses etc.

In realizing process of the present invention, contriver finds that prior art exists resistance impact capacity not enough, and the performances such as its sound-proofing and uvioresistant are general, therefore, are badly in need of developing a kind of doubling glass with all round properties.

Utility model content

In order to solve the problem of prior art, make doubling glass there is the external shock of better resistance, improve antitheft, sound insulation and ultraviolet resistance, the utility model has supplied a kind of doubling glass, and described technical scheme is as follows:

A kind of doubling glass, it comprises two sides glass body and is arranged at the PVB film between glass body described in two sides, described PVB film is fixing by glass body bonding described in two sides, and described PVB film is the heat insulation film of PVB through heat insulation nano antimony doped tin oxide or the processing of heat insulation nano tin-doped indium oxide.

Further, the integral multiple that the described heat insulation film thickness of PVB through heat insulation nano antimony doped tin oxide or the processing of heat insulation nano tin-doped indium oxide is 0.38mm or 0.38mm.

Heat insulation nano tin-doped indium oxide in described PVB film and the grain diameter of antimony doped tin oxide are 15-50nm.

Preferably, the grain diameter of the heat insulation nano tin-doped indium oxide in described PVB film and antimony doped tin oxide is 25-40nm.

Described nano antimony doped tin oxide or nanometer tin-doped indium oxide account for 1.5～3.5% of described PVB film total mass.

Glass body described in two is respectively a kind of in float glass, online low-e glass, off-line low-e glass, coated glass, flame resistant glass and tinted shade.

The beneficial effect that the technical solution of the utility model is brought is:

The utility model is by adopting the heat insulation film of PVB with transparent heat-insulated nano antimony doped tin oxide or nanometer tin-doped indium oxide to make doubling glass have following several large feature:

(1) security: when being subject to external shock, because elastic PVB film has the effect of impact-absorbing, can stop alluvium to penetrate, even glass breakage, also can only produce similar araneose crackle in small, broken bits, its fragment firmly sticks on PVB film, can avoid causing personal injury or property damage because glass drops.No matter at right angle setting still tilts to install, and it all can withstand penetrating of accidental impact, and monolithic glass still keeps complete, can continue to keep out shock and shading wind and rain until change.

(2) anti-theft (penetration-resistant): the PVB film through transparent heat-insulated nano antimony doped oxidation or tin-doped indium oxide processing is applied in doubling glass; make doubling glass very tough and tensile; even if robber strikes glass to split; because middle layer glass adheres to each other firmly; still keep globality; robber cannot be entered indoor, the person and property are had to provide protection." two folders one " glass of standard can be kept out penetrating of general alluvium; Even if suffer that opening appears in strong destruction, its breach is also minimum.Once destroy, defendance effect is still played to buildings in middle layer, until glass is changed.

(3) sound-proofing: glass is that a kind of ancient iron substance is not effective noise barrier, if noise conducts by glass, indoor people is had to impact; Because PVB film has the damping function to sound wave, laminated glass can effectively suppress the propagation of noise, and the buildings that is positioned at especially airport, station, downtown area and road both sides is installed after laminated glass, and its soundproof effect is obvious.

(4) solar energy control characteristic (anti-ultraviolet function): natural light conduction plays an important role in window design; but too many sunlight also can cause too high heat; laminated glass has various stable painted; PVB film with transparent heat-insulated nano antimony doped tin oxide particle can sponge more than 99% ultraviolet ray; energy in visible ray and infrared wavelength spectrum is controlled heat gain; contribute to like this to protect valuable furniture, wall chart, exhibit or commodity, to avoid the impact of ultraviolet radiation and fading of producing.Most of absorbed energies are through radiation and convection current are conducted outdoor and lost again.
