Problems solved by technology

However, after the current styrene-acrylic emulsion is coated with paper substrates, there are the following defects: 1. The general base paper will be hard after being coated with styrene-acrylic emulsion, so that the base paper lacks softness and is unfavorable for the adhesion of the pasted object; 2. 1. After the general styrene-acrylic emulsion is coated on the paper substrate, the surface of the paper substrate is matte, which affects the appearance of the paper substrate; 3. After the general styrene-acrylic emulsion is coated on the paper substrate, the paper substrate The base material will be sticky, which will cause the quality problem of paper sticking
4. The current conventional styrene-acrylic emulsion synthesis takes a long time, usually more than 10 hours, high cost and complicated operation

Abstract

The invention discloses styrene-acrylic emulsion coating a paper substrate and a preparation method thereof. The preparation method disclosed by the invention comprises the following steps: (1), adding a first mixed component in an emulsification tank, rapidly stirring, slowly adding a mixed monomer of a second mixed component in the emulsification tank, and stirring to form pre-emulsion; (2), adding a third mixed component into a reaction kettle to stir; (3), adding a fourth mixed component when the temperature of the reaction kettle is slowly increased to 76-92 DEG C; and (4), continuously stirring and reacting, simultaneously titrating reactants in the reaction kettle by using a fifth mixed component and the pre-emulsion obtained in the step (1) when the temperature of the reaction kettle is up to 82-95 DEG C, and continuously reacting with heat preservation after titrating so as to obtain the styrene-acrylic emulsion. The styrene-acrylic emulsion disclosed by the invention is reasonable in preparation process, steady in property, low in production cost and good in isolation anti-osmosis property and can be widely applied in all kinds of fields of sealing or sticking; and in particular, the styrene-acrylic emulsion is applied to an adhesive tape of the paper substrate and the like.

Description

technical field [0001] The invention relates to a styrene-acrylic emulsion, in particular to a styrene-acrylic emulsion applied to paper for isolation and protection, a preparation method and application thereof. Background technique [0002] At present, ordinary paper substrates cannot provide isolation protection without coating styrene-acrylic emulsion. When the paper substrate is coated with silicone oil or pressure-sensitive adhesive, it will cause penetration, which is not conducive to operation and affects the performance and quality of the tape. Therefore, a certain amount of coating is carried out on the base paper of the paper-based adhesive tape to achieve the effect of isolation and protection; at the same time, the softness of the base paper, the certain glossiness of the surface of the paper base material and the non-stickiness of the surface of the paper base material are guaranteed. Therefore, in order to meet the needs of the market, the industry has invent...
