Description

Double-channel sealing material of vacuum glass and vacuum glass
Technical Field
The invention relates to vacuum glass applied to the fields of buildings, electric appliances, automobiles and the like.
Background
Vacuum glass formed by compounding a plurality of glass plates is also a subject of competitive research because of its outstanding sound-insulating, heat-insulating and heat-preserving properties.
The existing sealing method of vacuum glass mainly comprises the following steps:
(1) and melting and sealing by using low-melting-point glass frit. The sealing temperature is generally about 400-500 ℃, and the low-melting-point glass frit is melted by flame or electric heat to complete the composite sealing between the glass plates. The process temperature exceeds 300 ℃, the strength of the toughened glass is reduced in the production process, and various defects are easily generated. When it exceeds 480 ℃, the strength of the tempered glass is permanently lowered, resulting in poor safety of the product. In addition, the low-melting glass adopted by the process is usually lead-zinc (PbO-ZnO) sealing glass, the material is not beneficial to environmental protection requirements for long-term development due to the harm of lead to the environment and human bodies, meanwhile, the processing equipment and the process are complex, the glass plate after composite sealing is often subjected to edge thermal stress, and therefore appropriate annealing treatment is carried out, and the production effect is greatly reduced. Although the frit has a low thermal conductivity, its relatively high gas permeability makes the vacuum glass less insulating.
(2) And sealing by adopting sintering type metal slurry. The sintering temperature of the metal slurry is above 500 ℃, then solder is placed in the middle of the sintering layer, and finally sealing is carried out through a metal brazing process. In the production process, the sintering temperature exceeds 480 ℃, which causes permanent reduction of the strength of the tempered glass, but the tempered glass must be tempered again in the subsequent process and is welded by adding a solder, so that the process is complicated and the safety of the glass is poor. The vacuum glass has poor heat insulation due to a large amount of high-heat-conductivity metal in the metal paste.
(3) Various plastics and resin materials are used for composite sealing between glass plates. Patent documents mention the use of organic glasses, such as: PC, ABS, LDPE, PVC, etc., and in other patent documents, PVB, EVA (EN), etc. are used as materials for making laminated glass, and the processing method is that the above materials are placed between two glass plates to make a prefabricated member, and then the prefabricated member is placed under proper conditions and pressed to obtain the laminated glass. This process is similar to the process of making laminated glass, although it can realize composite sealing between glass plates, most plastic and resin materials have gas permeability and moisture permeability much higher than that of glass, and most organic materials are only physically adhered to the glass surface, so it is difficult to ensure that the joint is not leaked, and once gas (including water vapor) is leaked, the sealing strength is weakened, dewing is generated in the interlayer, and the glass is mildewed. In addition, the aging problem of the organic material also directly affects the sealing effect and the service life of the composite glass plate with the lapse of time.
(4) The vacuum glass is sealed by adopting the multi-layer low-melting-point brazing material, although the sealing temperature is low and the glass toughening temperature is ensured, the strength of the welding material is low, so that the sealing material is easy to generate defects under the condition that the vacuum glass bears the force, and the vacuum glass product fails. And because of the multilayer structure, delamination can occur in certain failure situations. The main components of the metal also make the vacuum glass have poor heat insulation.
