preparation example Construction

[0034] The present invention also provides a preparation method of styrene polymer, according to which the above-mentioned styrene polymer can be prepared, such as figure 1 shown, including the following steps:

[0035] Step 100, adding 20-25 parts by weight of an organic solvent;

[0036] Step 200, mixing 20-60 parts by weight of unsaturated monocarboxylic acid with an organic solvent, and stirring to obtain a mixed solution A;

[0037] Step 300, mixing 10-40 parts by weight of esters with mixed solution A, and stirring to obtain mixed solution B;

[0038] In step 400, 0.4-8 parts by weight of additives are mixed with the mixed solution B, and reacted for 12-14 hours under stirring to obtain a styrene polymer.

[0039] Each of the above steps is carried out at a reaction temperature of 95-110°C.

[0040] Specifically, the organic solvent includes one or more of PGMEA (Propylene glycol monomethyl ether acetate), PM (Proprylene glycol monomethyl ether, propylene glycol methy...

Abstract

The invention discloses styrene polymer and a preparation method thereof. The styrene polymer comprises the following raw materials in percent by weight: 20 to 25 percent of an organic solvent, 20 to60 percent of unsaturated monocarboxylic acid, 10 to 40 percent of esters, and 0.4 to 8 percent of an additive. The invention provides the styrene polymer which has a quick-drying characteristic, is high in resolution and fast in light sensitivity, has certain alkaline solubility, and is suitable for high precision line coating preparation. The invention further provides a preparation method of the styrene polymer. Through the adoption of the method, the styrene polymer can be prepared, and the molecular weight of the obtained styrene polymer can be adjusted through the adjustment of temperature and the additive amount of the additive during the reaction process.

Description

technical field [0001] The invention relates to a styrene polymer and a preparation method thereof. Background technique [0002] Coating glue is also called common coating, which is a special formula of coating adhesive. Coating glue is used to coat products or circuit boards, and the permanent coating formed after the coating glue is cured is used to separate water vapor or pollutants in the atmosphere, so as to achieve the purpose of protecting the circuit. The resolution of traditional inks is poor, and the inks need to be dried after coating. Many inks on the market lose their alkaline elution properties after drying, and have poor alkali solubility. Contents of the invention [0003] The object of the present invention is to overcome the deficiency of prior art, provide a kind of styrene polymer and preparation method thereof. [0004] Scheme of the present invention is realized like this: [0005] A styrene polymer, comprising the following raw material component...
