Special paper styrene acrylic lotion adhesive formula: styrene acrylic lotion is a copolymer lotion of styrene and acrylic monomers. In order to improve the stability of styrene acrylic lotion and endow polymer lotion with alkali thickened parts, proper amount of (methyl) acrylic acid or other unsaturated carboxylic acid is usually added for copolymerization.

Through the participation of styrene in copolymerization, the introduction of styrene segments into the copolymer can improve the alkali resistance, water resistance, hardness, antifouling and anti pulverization of the polymer coating film, making it a very versatile product. At the same time, its cost is lower than that of pure acrylic lotion.

Styrene can be polymerized through several different processes, such as free radicals, anions and cations. At the same time, styrene is one of the few monomers that can carry out high-temperature thermal initiation polymerization. It makes styrene acrylic lotion at a high temperature above 120 ℃ to generate free radicals that can initiate polymerization. The thermally initiated polymerization of styrene has been industrialized. Polystyrene is mainly produced by bulk method, suspension method and lotion method in industry. Styrene is rapidly oxidized in air to form oxides of aldehydes and ketones.

Free radicals will be formed when heated, and the rate of forming free radicals will increase significantly when heated to 120 ℃. In addition, the wholesale price of special paper, styrene and propylene is affordable, and you want to buy it as soon as possible.

Characteristics of styrene-acrylic surface sizing agent for special paper:

1. This product has good waterproof effect, and its surface water absorption can reach below 60g/m2 after use.

2. This product can be used together with anionic and non-ionic auxiliaries (such as CMC), starch, acid dyes and fluorescent brighteners. Generally, it is compounded with starch for surface sizing.

3. Within a reasonable range of use, this product will not reduce the surface tension of the liquid and will not produce a lot of foam.

4. The sizing degree has been generated when the paper leaves the machine. However, when the drying is not sufficient, there is a certain maturing period of sizing.

5. This product is non-toxic and can be used for food packaging paper.
