AI Technical Summary

Problems solved by technology

[0002] Gasoline-resistant resins are mainly used in fuel tanks, machine tools and other industrial parts that require oil-resistant corrosion. Commonly used acrylic resins have disadvantages such as rapid softening of the paint film after film formation, rapid loss of gloss, and inability to recover the paint film after the oil volatilizes.

Embodiment 1

[0019] 1, a kind of preparation method of high hardness gasoline-resistant acrylic resin, it comprises the following steps:

[0020] (1) Mix 15 grams of styrene, 25 grams of methyl acrylate, 6 grams of hydroxyethyl acrylate, 1.5 grams of acrylic acid, and 2.25 grams of initiator BPO (90% of the total amount) to obtain a mixed monomer;

[0021] (2) 30 grams of xylene and 20 grams of butyl acetate are dropped into the reactor, heated to a reflux state;

[0022] (3) Put the mixed monomer of step (1) into the drip tank, and evenly drop the mixed monomer into the reactor of step (2) with 2.5-3 hours; Hour; insulation completes and adds remaining initiator 0.25 gram (10% of total amount); Reaction 2 hours under the continuation reflux state;

[0023] (4) Cool down to 100 degrees, filter to obtain acrylic resin.

Abstract

The invention discloses high-hardness and gasoline-resistant acrylic resin and a preparation method thereof. The high-hardness and impact-resistant acrylic resin is prepared from the following raw materials in percentage by weight: 15 to 25 percent of styrene, 2.5 to 25 percent of methyl acrylate, 5 to 10 percent of hydroxyethyl acrylate, 0.25 to 1.5 percent of acrylic acid, 0.5 to 2.5 percent of initiator and 50 percent of organic solvent. According to the preparation method, optimal raw material composition and proportion are screened and obtained through abundant experiments; an optimal synthetic process is selected through the abundant experiments. The whole preparation process is reasonable in design; the acrylic resin with excellent gasoline resistance is prepared.

Description

technical field [0001] The invention relates to a paint, in particular to an environment-friendly high-hardness gasoline-resistant acrylic resin and a preparation method thereof, belonging to the technical field of polymer materials. Background technique [0002] Gasoline-resistant resins are mainly used in oil tanks, machine tools and other industrial parts that require oil-resistant corrosion. Commonly used acrylic resins have disadvantages such as rapid softening of the paint film after film formation, rapid loss of gloss, and inability to restore the paint film after the oil volatilizes. Contents of the invention [0003] Purpose of the invention: the purpose of the invention is to address the deficiencies in the prior art, through a large number of experiments, to provide an environmentally friendly high hardness, gasoline-resistant acrylic resin and its preparation method. [0004] Technical scheme, for realizing above object, the technical scheme that the present in...
