Problems solved by technology

[0005] At present, the development trend of domestic laminated glass inks is rapid, because the technical requirements of laminated glass inks are relatively low, and they have the potential to replace imported inks. However, there is no such thing on the market that has an acid resistance of more than 8 hours, a wide sintering range, and can cover different sizes. Curvature glass, can match the laminated glass ink used in silver paste, most of the products can only meet one or two requirements

Abstract

The invention discloses wide-range sintered glass ink for automobile laminated glass, which belongs to the technical field of ink materials, and comprises the following components in percentage by weight: acid-resistant glass powder, low-temperature glass powder, silver paste matched glass powder, copper-chromium melanin, varnish and a diluent. The invention also discloses a preparation method ofthe wide-range sintered glass ink for the automobile laminated glass, the ink prepared by the method does not contain harmful heavy metals such as lead and cadmium, meets ROHS10 and sustainable development requirements, and is non-toxic, harmless and pollution-free in the preparation process; the softening point of the ink is 450 to 530 DEG C; the thermal expansion coefficient is 60*10 <-7 > / DEG C-90*10<-7 > / DEG C, the Toyota acid-resisting time is longer than 8 h, the sintering temperature range is 520-720 DEG C, glass of different sizes and different curvatures can be covered, silver paste sintering can be matched, cracks are not generated, and the method can be used for forming front windshield laminated glass of cars, SUVs, middle buses and buses.

Description

Technical field [0001] The invention belongs to the technical field of ink materials, and specifically relates to a wide-area sintered glass ink for automobile laminated glass and a preparation method thereof. Background technique [0002] Automobile laminated glass is made of PVB film glued between two pieces of glass. Due to its good safety performance, glass fragments will not splash but adhere to the PVB film when impacted. It is mainly used as automobile front windshield, interlayer Glass ink is applied to the edges of the glass to effectively reduce the UV transmittance, prevent chemical changes in the glue used to bond the glass and the car body, and give the car an aesthetic effect. [0003] Automobile laminated glass can be divided into small-sized laminated glass such as bridge cars and SUVs, medium-sized laminated glass such as medium-sized buses and trucks, and large-sized glass such as buses and buses according to the size of glass forming and the magnitude of curvatur...
