Problems solved by technology

In addition, water-based resins cannot be used in aerosol spray paint due to their drying speed, compatibility with propellants, and stability.
Alcohol-soluble resins on the market are generally used in inks, and the use of aerosol spray paints has not been disclosed in China.

preparation example Construction

[0033] Second, the preparation method of alcohol-soluble resin, see figure 1 , including the following steps:

[0034] Step 1: Weigh an appropriate amount of various monomers and mix them evenly for later use, dissolve benzoyl peroxide in the mixed monomers, and then measure an appropriate amount of mixed alcohol solvent for later use;

[0035] Step 2: Add all the mixed alcohol solvent and 10%-15% mixed monomer in a device equipped with stirring and reflux (for example: a four-necked flask), and add an initiator, heat up to 80°C-85°C, and stir Heating to reflux, reacting for 1-2 hours;

[0036] Step 3: Add the remaining 85%-90% of the mixed monomer dropwise in 4-5 hours, keep warm for 2-3 hours, and add azobisisobutyronitrile three times; keep the reaction temperature unchanged, and the reaction is carried out for 5 - end after 6 hours;

[0037] Step 4: When the temperature of the material in the reactor drops below 50°C, add organic amine to adjust its pH value to 8-9, the...

Abstract

The invention relates to alcohol-soluble resin, a preparation method thereof and a method for manufacturing aerosol spray painting by utilization of the alcohol-soluble resin. The alcohol-soluble resin is prepared by polymerization of mixed monomers in a mixed alcohol solvent, wherein the mixed monomers comprise the following compositions in portion by weight: 55 to 75 portions of acrylic ester, 8 to 20 portions of vinyl acetate, and 20 to 35 portions of active functional group monomers. The method for manufacturing the aerosol spray painting by adoption of the alcohol-soluble resin comprises the following steps: the adequate alcohol-soluble resin is provided and mixed with pigment filler, added with an auxiliary agent, mixed and grinded to prepare slurry; and the slurry is added with the auxiliary agent for color blending, and diluted by the mixed alcohol solvent to the required concentration, and the alcohol-soluble aerosol spray painting is prepared. The alcohol-soluble resin is synthesized by adoption of a plurality of monomers such as the acrylic ester and special monomers containing functional groups and adoption of mixed alcohol as a solvent, and simultaneously can meet the performance requirements and reach the environment-friendly standards when being used on the aerosol spray painting after selection of suitable auxiliary agent.

Description

technical field [0001] The invention relates to the field of spray paint, in particular to an alcohol-soluble resin, a preparation method thereof and a method for making aerosol spray paint with it. Background technique [0002] Aerosol spray paint is generally composed of resins, pigments, additives and solvents. The performance of aerosol spray paint and which solvent is used as a diluent in use are generally determined by the resin. The air paint spray paint currently used generally uses quick-drying acrylic resin or modified acrylic resin. They use benzene, ketone and ester solvents as diluents, which will volatilize and discharge into the air during use. It is easy to cause serious environmental pollution. Therefore, with the improvement of environmental protection requirements and the restrictions on volatile solvents at home and abroad, it is an urgent demand for the market to develop new aerosol spray paints that are both environmentally friendly and cheap. In addi...
