Abstract

The invention discloses glass slurry for an automobile compression molding front windshield. The glass slurry is prepared from the following raw materials in parts by weight: 65-85 parts of glass powder; 15-35 parts of an inorganic pigment; 18-30 parts of varnish; the glass powder is prepared from the following raw materials in parts by weight: 40-60 parts of Bi2O3; 25-35 parts of SiO2; 0-10 partsof B2O3; 0-10 parts of ZnO; 0-5 parts of ZrO2; 0-10 parts of TiO2; 0-5 parts of Al2O3; 0-2 parts of Fe2O3; 0-2 parts of NaF; 0-5 parts of MgO; 0-5 parts of CaO; 0-5 parts of Li2O; 0-2 parts of K2O; and 0-5 parts of Na2O. The invention further provides a preparation method of the glass slurry for the automobile compression molding front windshield. The preparation method comprises the following steps: preparing the glass powder; preparing varnish; preparation of slurry. The glass slurry has excellent acid resistance and adhesion resistance when applied to the automobile front windshield, and also has the advantages of printability, covering property, proper expansion coefficient range and the like.

Description

technical field [0001] The invention relates to the technical field of glass paste, in particular to a glass paste for press-molded front windshields of automobiles and a preparation method thereof. Background technique [0002] With the rapid development of the automobile industry, automobiles have entered thousands of households, changed people's lives, and become people's assistants and companions in work and life, which also drives the development of the automobile retail industry. As an indispensable part of the automobile production process, the glass paste for automobiles is also developing rapidly. The demand for glass paste in the automobile industry has also greatly increased, which promotes the research on automobile glass paste. [0003] Automobile glass paste refers to the use on the edges of the tempered glass of automobiles to effectively reduce the ultraviolet transmittance, prevent the chemical change of the glue used to bond the glass and the car body, and ...
