A kind of chrome-plated automatic spray paint and preparation method thereof

Abstract

The invention discloses a chroming automatic spray paint and a preparation method thereof. The spray paint is composed of components A and B, wherein the component A comprises 8-11 parts of petroleum resin, 2-5 parts of floating aluminum-silver paste, 18-23 parts of dimethyl carbonate, 2-5 parts of acetone, 3-6 parts of isopropanol, 17-25 parts of dichloromethane and 4-8 parts of isoparaffin, and the component B is LPG (Liquefied Petroleum Gas) by weight, wherein the ratio of the dosage of LPG to the weight of the paint materials is 0.52-0.56. The chroming automatic spray paint is free of environmental pollution and harmless to the atmosphere; the chroming automatic spray paint is stable in performance, applicable to different angles and spaces, good in sprayability, and high in jet rate; the spray paint is self-dry at the normal temperature and can be dry quickly; the paint film is high in fullness, has excellent combination properties such as metallic texture and flexibility, and also has strong metal mirror decoration effect which is comparable with that of electroplating; the paint film is also capable of effectively resisting ultraviolet radiation and enhancing the ageing resistance of the decorated article, and has wonderful anti-rusting and protection functions.

AI Technical Summary

Problems solved by technology

[0002] At present, the common chrome-plated automatic spray paint products use some harmful benzene solvents as raw materials, and have certain toxicity as raw materials. The products pollute the environment during construction, are easily inhaled, absorbed through the skin, and are irritating to the skin and mucous membranes. Nervous system has anesthesia effect, short-term inhalation of higher concentration may cause obvious eye and upper respiratory tract irritation symptoms, long-term exposure may cause neurasthenia syndrome, hepatomegaly and other symptoms, affecting people's health.

[0003] The characteristics of the existing chrome-plated automatic spray paint product formulation process are mainly using benzene-containing resin, silver paste, and benzene as solvents, so that the product can reach a stable state, and the paint film can meet various index requirements for chrome-plated spray paint (such as metal mirror surface decoration effect etc.), if the raw materials containing benzene are removed, this kind of product will easily deteriorate and turn black after a few days of storage, and there is no mirror decoration effect at all. The key is to find a solvent that can completely replace benzene to avoid it. Blackening and unstable factors, it is impossible to replace benzene with one solvent alone. The volatilization speed and pH of various solvents must be considered to synthesize the performance of each component in order to produce stable and mirror-like products. Effect chrome automatic painting

[0004] It can also be completely replaced by other benzene-free resins, silver pastes, and solvents (such as ketones, esters, etc.) to make chrome-plated automatic spray paint, but the spray paint will be stored at room temperature for 1 month and after 7 days at a constant temperature of 50°C. Changes, the sprayed paint film will become dark and black, there is no metal mirror effect at all, and the silver paste will thicken, resulting in no spraying, etc.
