High-temperature inorganic ink based on low-melting-point glass powder and preparation method thereof

Abstract

The invention discloses a high-temperature inorganic ink based on low-melting-point glass powder, and belongs to the technical field of ink. The inorganic ink comprises the following raw materials inparts by weight: 40-60 parts of low-melting-point glass powder, 15-20 parts of an inorganic pigment, 25-35 parts of water-based high-viscosity resin and 12-15 parts of zirconium oxide. The invention further discloses a preparation method of the high-temperature inorganic ink based on the low-melting-point glass powder. The preparation method comprises the following steps: step 1, adding low-melting-point glass powder, water-based high-viscosity resin and zirconium oxide into a container according to the formula, uniformly stirring to form a mixture, and controlling the temperature to be 50-70DEG C; and step 2, adding an inorganic pigment into the mixture obtained in the step 1, and continuously stirring for 30-50 minutes to obtain the high-temperature inorganic ink. According to the method, the high-temperature inorganic ink is prepared from the low-melting-point glass powder, in the application process, on the premise that certain hardness is maintained, the rigidity is reduced, thetoughness is enhanced, and the impact resistance and the tear resistance are improved at the same time.

Description

technical field [0001] The invention belongs to the technical field of ink, and in particular relates to a high-temperature inorganic ink based on low-melting glass powder and a preparation method thereof. Background technique [0002] High-temperature inorganic ink means that the sintering temperature is 430-850°C. After high-temperature sintering, the inorganic ink is firmly clad / fused / sealed with glass, metal, ceramics, etc. to form a layer of hard, heat-resistant, weather-resistant, and durable. Inorganic coating of chemicals. It is a high-temperature inorganic ink prepared with low-melting-point glass powder as the base material. The low-melting-point glass powder is melted to form a film at high temperature and combined with glass or metal. The obtained high temperature inorganic ink has the characteristics of high bonding strength, high temperature resistance, high hardness, good resistance, high temperature resistance, high weather resistance, hard and brittle, and ...

AI Technical Summary

Problems solved by technology

The obtained high temperature inorganic ink has the characteristics of high bonding strength, high temperature resistance, high hardness, good resistance, high temperature resistance, high weather resistance, hard and brittle, and the use conditions of products such as glass and metal components are relatively harsh, and unavoidable during use It will be impacted, but the low-melting point glass powder obtained by the prior art has high hardness, hard and brittle, and cannot be subjected to strong impact and tearing, and the impact resistance is insufficient, and the toughness of the high-temperature inorganic ink prepared by it is reduced.
