Technical field
The present invention relates to automobile heat insulation sun-shielding glass technical field, relate in particular to transparent heat-insulated sun-proof nanometer thermal insulation material of automobile glass of height of a kind of excellent performance and preparation method thereof and application.
Background technology
According to the rule of development of developed country's market for automobiles such as Japan, the U.S., in the time that GDP per capita reaches 1000 dollars, car starts to enter family.Taking cars ' entry into family as mark, market for automobiles also must enter the fast-growing period.Within 2003, China's GDP per capita surmounts 1000 dollars first, and according to relevant department prediction, to 2015, China's GDP per capita will reach 3000 dollars, our judgement, and Car Industry will welcome the relatively long growth stage.Vehicle glass is as the Important Platform of automobile important component part and car internal and external exchange, bearing keep out the wind, the basic function of rain cover and daylighting.And along with the pursuit of people to higher quality of life, more and more higher in the requirement of the aspects such as attractive in appearance, comfortable and environmental protection to automobile, novel vehicle glass also develops to meet the growing needs of people one after another.And there is the automobile glass of shining point, under the policy prerequisite of active response national green environmental protection, can contribute for energy-saving and cost-reducing, can for driver and passenger provide comfortable can people, safe and reliable space, they will cause people's concern and be subject to popular favor.
We know that most of heat of automobile is all to enter from front windshield, and the light penetration of car safety law regulation front windshield must be more than 75%.General vehicle explosion-proof film does not have good sun-proof result under high transmission rate condition, can meet expensive the going against accepted conventions of price of the sunscreen film of these two kinds of conditions simultaneously, and car load pad pasting easily will units up to ten thousand, and general human consumer can not afford at all.In addition, the front windshield of automobile is formed by two blocks of glass and PVB doubling, and this does not need to carry out explosion-proof pad pasting as safe explosion-proof glass.
Reflect the production technology of sunscreen film for tide of motorism from initial dyeing (tinting) technique, Al metallizing Fool, vacuum plating aluminium lamination and dyeing hybrid films, magnetron sputtering metallic membrane to magnetron sputtering Multi-layer thermal reflecting metallic film.These heat reflection sunscreen film have certain sun-proof result.Along with the continuous progress of technology, the performance of product also improves constantly, but its production cost but constantly increases, production process becomes complicated.And which plate is existing market do not have clearly to indicate which class is its production technology belong to, all adopt confuse different concepts and introduce its product by some scientific and technological nouns, as for whether this technology of appropriate adoption of this product, that textual criticism of just having no way of, makes us confused.
The Solar reflection-type automobile front windshield occurring on market recently, although can meet the requirement of relevant laws and regulations to windshield visible light transmissivity, can to a certain degree intercept again sun power.The Double-layer vacuum reflecting windscreen that for example application number is 02237220.2, application number is that the patents such as 200720190635.8,200720190638.1,200720190639.6 transparent, conduction, heat reflective multi-film automobile glass are all to make in this way, but employing magnetron sputtering method, whole plant cost of investment is too high, production process requires very harsh, and the limit portion of coated glass need to carry out the demoulding processing after mask and the plated film before plated film, otherwise laminated glass can produce and come unstuck and the defect such as rete oxidation from limit portion.Because rete is the mantle that off-line is coated with, film just needs special care in the processing treatment in later stage, with the generation of the defect such as anti-scratch, oxidation.At present little in the patent of this part, the related products of act in good faith on the market vehicle glass company and Fu Yao vehicle glass company is in a small amount of sale.
The automobile adhesive film that promote in car detailing shop, although can play sun-proof effect, greatly reduce the transmitance of visible ray, make the dimmed driver of light in car easily produce tired, also be not easy to observe the situation of vehicle-surroundings, make especially the passage situation of pedestrian, non power driven vehicle.In the time that Vehicular night travels or take a sudden turn, be difficult to see through glass and see the road conditions in front clearly, when special, be not easy to observe to entering the vehicle at reversing face dead angle.And the weather resistance of pad pasting is bad, under solar radiation, be easy to bubble, come unstuck, variable color etc., leave a lot of potential safety hazards.
On market, occurred the novel heat-insulation glass material that some are formed by thermal insulating coating film recently, its effect of heat insulation product relatively has in the past had very high lifting, and visible light transmissivity can reach 85%.But heat-protecting glass rete physical and mechanical properties does not reach requirement, hardness is not high, not wear-resisting wiping.The heat insulation rete that the preparation method of the automobile finish of a kind of nanometer heat insulation material that for example application number is 200810026858 makes has certain effect of heat insulation, but physical and mechanical properties is unsatisfactory.
