preparation example Construction

[0024] The preparation method of anti-adhesive mortar resin is:

[0025] (1), take each raw material respectively by above-mentioned mass percentage;

[0026] (2), dissolving: dissolve sodium lauryl sulfate with hot water, then cool;

[0027] (3) Pre-emulsification: Combine cooled sodium lauryl sulfate, styrene, butyl acrylate, acrylic acid, N-methylol acrylamide, vinyl triethoxysilane coupling agent, nonionic emulsifier 1. Water and vinyl silicone oil accounting for 90% of the total amount are sequentially added to the disperser to disperse, and after the dispersion is complete, a pre-emulsion is made;

[0028] (4), initiator: ammonium persulfate is mixed with water accounting for 5% of the total amount to form an initiator;

[0029] (5), initial addition: after the temperature of the reactor reaches 75°C, start to initially add 5 to 10% of the initiator and the initial addition of 5 to 10% of the pre-emulsion to the reactor;

[0030] (6) Dropping: After the reaction is st...

Embodiment 1

[0038] The cooled 2.5g sodium lauryl sulfate, 110g styrene, 270g butyl acrylate, 3g acrylic acid, 2g N-methylolacrylamide, 2g vinyltriethoxysilane coupling agent, 6g nonionic emulsifier Add 250g of water and 5g of vinyl silicone oil to the disperser in order to disperse. After the dispersion is complete, a pre-emulsion is made; after the temperature of the reactor reaches 75°C, start to add 10% of 0.5g ammonium persulfate to the reactor. The initiator made with 13g of water and the initial 10% pre-emulsion, after the reaction is stable, start to drop the pre-emulsion and the dropwise addition of the initiator. During the dropping process, the temperature is controlled at 85°C, kept for 1 hour, and then cooled to 50-60°C, then drop in 0.3g tert-butyl hydroperoxide, 0.3g sodium bisulfite and 14g water, keep warm for 20 minutes, then lower the temperature to below 45°C, adjust the pH value of the glue resin with ammonia water to adjust to 7.0±0.5, the product is obtained.

Abstract

The invention discloses anti-stick mucilage resin and a preparation method thereof. The mucilage resin comprises butyl acrylate, styrene, vinyl silicone oil and the like. The preparation method of the anti-stick mucilage resin comprises the steps of pre-emulsification, initial adding, dropwise adding, postprocessing and the like. The vinyl silicone oil is used as a functional monomer to take apart in a reaction so as to achieve crosslinking with resin macromolecules in the polymerization process, so that the finally-obtained mucilage resin has the characteristics of the vinyl silicone oil, and therefore the stick resistance of the dried mucilage resin is improved.
