Abstract

The application discloses a liquid silicone acid spraying agent and a spraying method and application thereof, and relates to the technical field of spraying. The liquid silicone acid spraying agent is prepared by mixing translucent silicone acid and translucent viscous liquid silicone acid with a viscosity of 150 pa.s at a ratio of 1:1. The spraying method of the liquid silicone acid spraying agent comprises the following steps: S1, cleaning the surface of a substrate to be sprayed; S2, uniformly spraying the liquid silicone acid spraying agent on the surface of the substrate by using a spray gun; and S3, heating the sprayed substrate at 120 DEG C for 60s to make it solidify and form. The liquid silicone acid spraying agent can be applied to the surface spraying of various vacuum cups and glass cups, can reach food-grade environmental protection performance, and can improve the appearance of the vacuum cup after spraying. After the glass cup is sprayed, the safety performance is improved, the unsprayed glass cup is scattered after being broken into pieces, while the sprayed glass cup is still an integral whole after being broken, so that the glass pieces can not cause injuries.

Description

Technical Field

[0001] This invention relates to the field of spraying technology, specifically to a liquid silica gel acid spraying agent, its spraying method, and its application. Background Technology

[0002] Silicone rubber is mainly composed of siloxane linkages containing methyl groups and a small amount of vinyl groups. The introduction of phenyl groups improves the high and low temperature resistance of silicone rubber, while the introduction of trifluoropropyl and cyano groups improves its temperature and oil resistance. Silicone rubber has good low-temperature resistance, generally remaining functional at -55°C, and reaching -73°C after the introduction of phenyl groups. Silicone rubber also exhibits outstanding heat resistance, capable of long-term operation at 180°C, and maintaining elasticity for weeks or longer at temperatures slightly above 200°C. It can withstand instantaneous temperatures exceeding 300°C. Liquid silicone rubber can be used for coating, impregnation, and potting.

[0003] Existing glass cups and thermos cups are generally coated with colored paint or patterns to enhance their appearance. However, ordinary paint is not environmentally friendly and does not improve the safety performance of the cups. Therefore, we propose a liquid silicone acid spraying agent, its spraying method, and its application to solve the problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to provide a liquid silica gel acid spraying agent, its spraying method, and its application, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a liquid silica gel acid spraying agent, wherein the spraying agent is made by mixing semi-transparent silica gel acid with a viscosity of 150 Pa·s and semi-transparent viscous liquid silica gel acid in a 1:1 ratio.

[0006] Preferably, the above-mentioned mixed coating is vulcanized into an elastomer by heating at 120°C for 60 seconds.

[0007] A method for applying a liquid silicone acid spray agent includes the following steps:

[0008] S1. Clean and sanitize the surface of the substrate to be sprayed;

[0009] S2. Use a spray gun to evenly spray the liquid silicone acid spray agent onto the surface of the substrate;

[0010] S3. Heat the sprayed substrate at 120℃ for 60 seconds to cure and shape it.

[0011] Preferably, the step further includes S4, applying colored masking ink to the surface of the liquid silicone acid coating on the substrate.

[0012] Preferably, in S2, the spraying angle is 90°, the ambient temperature is 24°C, the humidity is 45%, the spraying distance is 200mm, the spray gun moving speed is 30cm / s, and the spraying pressure is 0.5Mpa.

[0013] The above-mentioned liquid silica gel acid spraying agent can be used in any of the following applications:

[0014] 1) Spray coating on the surface of the glass;

[0015] 2) Spray coating on the surface of the thermos cup.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) The liquid silica gel acid spraying agent of the present invention can be applied to the surface spraying of various thermos cups and glass cups, and can achieve food-grade environmental protection performance. After the thermos cup is sprayed, the aesthetics of the cup body can be improved. After the glass cup is sprayed, the safety performance is improved. When an unsprayed glass cup is broken, it forms glass shards that scatter everywhere, while when a sprayed glass cup is broken, it remains a whole, thus avoiding accidental injury caused by glass shards.

[0018] (2) The liquid silica gel acid spraying agent of the present invention can be cured quickly after heating, which improves the efficiency of spraying work. The material has high elasticity and excellent temperature resistance, weather resistance and water repellency. It is also non-toxic, non-irritating and has strong applicability.
