Abstract
The invention discloses a novel environment-friendly paper surface glazing finishing emulsion and a preparation method thereof. The emulsion comprises, by weight, 5 to 40% of a natural high-molecular material, 40 to 60% of a hard monomer, 30 to 50% of a soft monomer, 0.01 to 5% of a functional monomer, 0.02 to 5% of a modifier and 0.2 to 0.5% of an initiator, with the balance being deionized water. The novel environment-friendly paper surface glazing finishing emulsion provided by the invention has the advantages of capacity of film forming at room temperature, nontoxicity, no odor, striking transparency, strong adhesion, good leveling performance, no discharge of organic volatile matters (VOC) and the like, overcomes the defects of a high glass transition temperature, low dual-component resin complex formulation, utilization of an emulsifier, a film forming auxiliary agent and the like of a conventional waterborne glazing agent, regenerable resources are fully utilized, a product is sanitary and biodegradable after cyclic usage, environmental pollution is reduced, and economy and environmental protection are realized.
Description
technical field [0001] The invention relates to a novel environmental protection paper surface glazing and finishing emulsion, in particular to a preparation method thereof. Background technique [0002] With the development of the market economy and the continuous improvement of human living standards, people pay more and more attention to the printing and decoration of various packaging and publications. The traditional BOPP and PET plastic-film composite paper has the advantages of high gloss, beautiful and durable, but it is not conducive to the recycling of waste paper, and it is easy to cause environmental pollution. With the development of society, human beings' awareness of protecting the living environment has also been continuously improved, and the coating of varnish on the surface of printed products has gradually replaced plastic film composite paper. Varnish can endow prints with good surface gloss, improve the wear resistance, water resistance, stain resistan...
