Abstract
First, two sides of glass plate are plated via sol-gel process and then the plated glass plate is hot-bent and/or toughened at sufficiently high temp. The product is esp suitable for building and automobile.
Description
The present invention relates to a kind of manufacture method of heat treatable double-sided coating glass and the product that obtains by this method.Especially relate to production and when high temperature such as hot bending, tempering are handled, still keep the so-gel coating technique of its plated film outward appearance and performance and thermal treatment process subsequently.
The existing method of making coated glass has metal vacuum coating and (magnetic control) sputter coating etc., this class coated glass is coating single side, have metal appearance and other metallicities though metal vacuum is tinted, can lose its distinctive metal appearance and performance when carrying out pyroprocessing.Magnetic is mixed existing report of technology of sputter coating, and the coated glass of this manufactured has good homogeneous, but mechanical life is low, therefore, can't stand processing such as tempering, hot bending.As everyone knows, on glass to obtain uniform coating be unusual difficulty crooked, for this reason, the researchist has carried out a large amount of trials to common coated glass, a kind ofly carry out plated film so that obtain at surface of plate glass, under the condition that keeps coating performance, it is heat-treated the technology of (as tempering, hot bending) then.
The Chinese patent 92112028.1 of U.S. PPG Industries Inc. application provides a kind of heat treatable metal vacuum coating technology; its method for making is: the film that contains picture chromium nitride or this metalloid of titanium nitride of oxidation can take place under coating high temperature on the substrate of glass, and outer coating can form the different metal protective layer on dense oxide top layer.This coated articles can bear crooked and so on pyroprocessing but unlikely oxidation and lose metal appearance.Also provide a kind of temperable coated articles simultaneously: containing as this metalloid film of titanium nitride of oxidation can take place under coating high temperature on the glass matrix with metallicity; outer coating tool has the silicon compound protective layer that forms durable layer and prevent the oxidation of containing metal substrate film, and carries out interior coating with metallic stabilizing layer.That the Chinese patent 92115388.0 of U.S. Guardian Industries Corp. application has proposed is a kind of " but improve thermal treatment sputter-coated glasses series of strata ", these series of strata comprise the metal level that is made of nickel or a kind of Langaloy, this plates the sealing coat that one deck is made of a kind of oxide compound of a kind of oxide compound of Pure Silicon Metal or nickel or Langaloy above metal level, this plates one deck above sealing coat be SnO by theoretical proportioning
2The protective layer of metal oxide.Before thermal treatment, said series of strata are plated on the glass substrate, thereby make glass with special plated film, this coated glass can be heat-treated under sufficiently high temperature so that it is carried out bending, heat reinforcement and/or modified.
Above-mentioned two patents are in order to solve its film performance problem of the maintenance of coated glass after thermal treatment, the sputtering film coating method that has adopted the metal vacuum coating respectively and improved, Chinese patent application 92112028.1 described coated articles have following structure: glass/M
1/ M
3/ silicon (M
2) dielectric substance, wherein M
1Be a kind of semi-conductor or metal alloy or its composition, M
2Be element a kind of in the silicon alloy target with the silicon bonded, M
3Be for example will prevent oxidation and metallike metallic compound that will be stable during tempering and so on pyroprocessing.The sputter-coated glasses the handled product that Chinese patent application 92115388.0 provides comprises a glass substrate, and the plated film series of strata comprise three layers on the substrate: the unoxidized basically metal level of one deck; The layer of metal protective oxide film; The sealing coat that one deck silicon or metal oxide or metal nitride are arranged one, two layer of centre.The manufacturing approach craft complexity of above-mentioned two kinds of heat treatable coated glasses, its plated film mode is coating, coating single side.
It is simple to the object of the present invention is to provide easy reliable, the coating liquid of a kind of technology to form, and rete stable mechanical performance, acid and alkali-resistance, weather also can stand the manufacture method of the double-sided coating glass that sufficiently high temperature heat-treats, and it comprises the following steps:
One, plated film step:
1. glass substrate-cleaning-oven dry,
2. melten gel-gel method plated film:
A. solution formula:
Butyl (tetra) titanate 8～15%
Dehydrated alcohol 80～90%
Methyl ethyl diketone 1～3%
Hydrochloric acid 0.08～0.15%
B. dip-coating
The glass that oven dry is good immerses in the above-mentioned coating liquid, and slow then crossing is lifted out liquid level evenly,
3. thermal treatment:
Glass behind the plated film is sent in the sintering oven, is warming up to 250 ℃ ± 20 ℃, is incubated 15 minutes, and continue to be warming up to 500 ℃ ± 20 ℃, and be incubated 30 minutes, cooling naturally then,
Two, heat treatment step:
1. film glass is carried out pre-treatment: blank cuts or reaches sample utmost point excision forming, and edging is handled, and washing is dry,
2. send in the horizontal roller formula annealing furnace and be heated near the softening temperature of glass,
3. if 1. flat pattern tempering is chilled to room temperature to wind in the cooling air grid and comes out of the stove just directly send into after the glass that heats is come out of the stove;
If 2. curved tempering carries out the glass that heats earlier after hot bending handles, send into and be chilled to room temperature to wind in the cooling air grid and come out of the stove.
Film coating method of the present invention is compared with existing film coating method, technology is easy, cost is low, adopt because of containing organic titanium compound and make the method for coated glass, the clear 56-96749 of Japanese Patent be will contain organic titanium compound solution spray to pyritous (550 ℃～600 ℃) sheet glass, described processing condition are wayward, and are coating single side, United States Patent (USP) 3660137 described coating process adopt dip-coating method, but its coating liquid is formed complicated cost height.The present invention can be on versicolor glass substrate plated film, dipping process is easy to control, its even film layer, difficult drop-off, acid and alkali-resistance, weathering resistance are good, the rete stable mechanical performance, anti-cutlery scratches, its optical property and chemical stability are as follows:
