Abstract
The invention relates to a preparation method of an adhesive for coated paper. The adhesive comprises raw materials of components in percentage by weight as follows: 40-60 parts of a common solvent, 20-40 parts of acrylate resin, 5-10 parts of vinyl acetate, 2-5 parts of rubber, 1-3 parts of pentaerythritol trimethylacrylate and 1-3 parts of an azo initiator. According to the coated paper adhesive prepared with the method, the problem of insufficient adhesion fastness of the coated paper is effectively solved, meanwhile, the production process of the adhesive is simple and easy, the cost is reduced, and the preparation method has very high popularization value for coated paper packaged products.
Description
Invention field
The present invention relates to sizing agent field, particularly relate to a kind of preparation method of the acrylic acid or the like sizing agent used on enamelled paper wrapped product.
Background technology
Enamelled paper is with the text paper made of body paper coating whitewash, is therefore also called coated printing paper, is mainly used in printing the Commdity advertisement, sample, commodity packaging, trade mark etc. of the front cover of senior books and periodicals and illustration, colored picture, various fineness.In the last few years, due to the rise of electronic product, the enamelled paper packaging possessing high glossy, planeness and glossiness progressively becomes by popular with packaging type, therefore increasing to the packaging demand of enamelled paper.Due to the paper that enamelled paper is after coatings, therefore when making wrapped product and the matching degree of sizing agent just require higher, current common sizing agent does not on the market have specificity and develops for enamelled paper, also there is the problems such as first viscous force is inadequate, usage quantity is bigger than normal during use, market also just progressively starts inquire into the sizing agent development problem used for copperplate stationery wrapped product.
A preparation method for enamelled paper sizing agent, have employed acrylic resin systems, can solve the problems such as enamelled paper wrapped product adhesive fastness and planeness very well, commercially there is not yet like product, and simultaneously relevant research article is also few.
Summary of the invention
The problems referred to above existed when the object of the invention is to solve enamelled paper packaging bonding and a kind of method of enamelled paper Novel adhesive of acrylic system is provided.
In order to achieve the above object, the invention provides a kind of preparation method of enamelled paper sizing agent, comprise operation as follows:
1) get the acrylate resin of 20 parts-40 parts, the vinyl acetate between to for plastic of 5 parts to 10 parts, the rubber of 2 parts-5 parts, the pentaerythritol acrylate trimethyl of 1 part-3 parts, the azo initiator of 1 part-3 parts are for subsequent use;
2) in reactor, add Conventional solvents and amount to 50-80kg, be heated to 50-80 DEG C, constant temperature, the step 1) acrylate resin weighed up and vinyl acetate between to for plastic are put in reactor;
3) unlatching is stirred and controlled stir speed (S.S.) is 500-600rpm, continues to stir 1-2h, above-mentioned raw materials is all dissolved;
4) the step 1) rubber weighed up, pentaerythritol acrylate trimethyl, azo initiator are put in reactor, improve stir speed (S.S.) to 600-1000rpm, continue to stir 3-5h and make reaction carry out completely;
5) stop heating and continue to stir, making material in reactor naturally cool to 20-30 DEG C, filtration product, obtain final sizing agent product.
Described acrylate resin refer in butyl acrylate resin, isobutyl acrylate resin, isoamyl acrylate resin, Isooctyl acrylate monomer resin one or more, described Conventional solvents is one or more in ethyl acetate, n-butyl acetate, propyl carbinol, propylene glycol monomethyl ether, propylene-glycol ethyl ether, and described azo initiator is Diisopropyl azodicarboxylate.
The enamelled paper sizing agent that the method is produced, develop for the problem not having specificity to be suitable for enamelled paper wrapped product in the market and verify, better can be applicable to enamelled paper packaging, effectively improve enamelled paper simultaneously and adhere to the inadequate problem of fastness, and the simple and cost of production process reduces, and has high promotional value for copperplate paper packaging group product.
