Abstract

The invention relates to special PVDC (Polyvinyl Dichloride) latex for lining paper. The PVDC latex comprises the following raw materials: a mixed monomer, auxiliaries, an initiator, an emulsifying agent, a seed emulsifying agent and deionized water, wherein the auxiliaries include ammonium acetate, ferrous chloride and nano inorganic silicon. The inorganic silicon in the nano inorganic silicon is one or more of silicon dioxide, silicon disulfide, sodium silicate, potassium metasilicate, aluminum silicate, calcium silicate, silicic acid and silicon carbide. The invention also provides a preparation method of the special silicon disulfide for lining paper. The auxiliary, namely the nano inorganic silicon is added into the PVDC latex, so that the stiffness of a paper sheet is increased effectively; in addition, the mixed monomer containing vinylidene chloride, methacrylamide, acrylic ester and acrylic acid as well as the initiator, the emulsifying agent, the seed emulsifying agent and the auxiliaries are adopted, so that the PVDC latex is prepared; and the prepared PVDC latex has good stability and has the characteristics of environmental friendliness, good air and oxygen resistance and particularly high stiffness when used for packaging cigarettes after being coated on the lining paper.

Description

technical field [0001] The invention relates to a special PVDC latex for lining paper and a preparation method thereof, which belongs to the field of new polymer materials. Background technique [0002] Cigarette lining paper is the paper packed between cigarette sticks and cigarette packs, and its main function is to prevent moisture and preserve fragrance. Cigarette lining papers currently used in the domestic and foreign markets include: 1. Composite aluminum foil lining paper, such as patent application CN1378013A, its production process is simple, and it is mainly made of aluminum foil, base paper and composite glue through composite equipment. Strong resistance, good barrier performance. However, the aluminum foil used is not easy to degrade and recycle, and does not meet the requirements of establishing an environmentally friendly society; 2. Vacuum aluminized lining paper, which is characterized by a low amount of aluminum, which is only 1 / 200 of the composite alumi...
