Embodiment 1

[0062] refer to figure 1 , this embodiment discloses a preparation method of quick-drying glue for office use, comprising the following steps: the following substances are all in parts by weight;

[0063] S1: Preparation of emulsion. Add 200 parts of deionized water into the first reaction vessel by weight, the first reaction vessel is an emulsification tank, and start stirring. Then add 11 parts of emulsifier, 100 parts of styrene, 350 parts of acrylate and 200 parts of vinyl acetate at the same time, and keep stirring until the material in the first reaction vessel is milky white to prepare an emulsion for later use. Among them, the acrylate is selected from methyl acrylate; the emulsifier is selected from polyoxyethylene ether.

[0064] S2: Aggregation stage. Add 250 parts of deionized water into the second reaction vessel, the second reaction vessel is a reaction kettle, and before adding the deionized water, first raise the temperature of the deionized water to 75° C.,...

Abstract

The invention relates to the field of office supplies, and particularly discloses office quick-drying glue and a preparation process thereof. The quick-drying glue is prepared from the following raw materials in parts by weight: 2-20 parts of an emulsifier, 50-150 parts of styrene, 200-500 parts of acrylate, 50-350 parts of vinyl acetate, 2-10 parts of an initiator, 1-5 parts of a pH buffering agent and 350-550 parts of water. The preparation process comprises the following steps: S1, preparing an emulsion; S2, performing a polymerization stage; and S3, carrying out post-treatment; and the office quick-drying glue is obtained. According to the quick-drying glue disclosed by the invention, styrene, acrylate and vinyl acetate are selected as monomers, so that the solid content can be effectively improved, the addition amount of water is reduced, and the drying speed of the water in the finally obtained glue is reduced, and therefore, the solidification speed of the prepared glue is high,and the paper bonding time is finally reduced.

Description

technical field [0001] The application relates to the field of office supplies, in particular to a quick-drying glue for office use and a preparation process thereof. Background technique [0002] In daily life, office, and study, people use and come into contact with liquid glue in large quantities to paste paper and various materials. [0003] For example, the Chinese patent of application publication number CN109486437A discloses a kind of environment-friendly glue for office use, including the following materials by mass: 10 parts of starch, 3 parts of resin, 8 parts of latex, 12 parts of catalyst, 6 parts of acetic acid, 3 parts of propanol , 4 parts of essence and 45 parts of water. The obtained glue has good adhesion, the two objects after adhesion are not easy to separate, has good environmental protection, has no damage to human health, does not produce pungent smell after application and has a delicate smell, and has low cost and good economic efficiency. When us...
