Abstract
The invention discloses a high gloss and high abrasion resistant water-based overprinting varnish and a preparation method thereof. The overprinting varnish comprises the following components: deionized water, water-soluble solid acrylic resin, non film-forming material, film material, ammonia water, water-soluble emulsion wax, wetting and leveling agent, defoaming agent and thickener. The overprinting varnish of the invention uses water as solvent; when the overprinting varnish is used, only water is volatilized, thus the overprinting varnish is environmentally friendly; and the overprinting varnish does not contain heavy metals and can pass through the volatile organic compound (VOC) detection, thus being a safe and green product. The product of the invention uses water-soluble acrylic emulsion as the main matrix which combines with water-soluble solid acrylic resin, thus the safety and environmental friend of the product can be further ensured; and by adopting the special raw material combination, the product has good printing and glazing effects, high transparency and lustrousness and excellent wear resistance and is color-fast and scratch resistant; and after printed and glazed, the product has good water resistance and is not easy to scratch.
Description
Technical field
The present invention relates to the printed apcksging material field.Relate to be used for behind the paper printing glazing specifically, improve a kind of high smooth high abrasion water-based coating oil of paper printing effect.
Background technology
Printing packaging industry now, People more and more are paid attention to the perfection of packing, and the most last layer coating oil of crossing of the paper after the printing is used for improving the glossiness of paper, prevent to fade to wipe flower.What be used for Lacquer finish in the market has water-based coating oil, UV coating oil, pure dissolubility coating oil and an oiliness coating oil, also has plenty of the compound BOPP film of employing.It is following at this these Lacquer finish products to be carried out market analysis:
1, UV coating oil: mainly form, use with a small amount of alcohol dilution during last machine, through the ultra violet lamp fast setting by epoxy acrylate, reactive thinner, light trigger, skimmer, flow agent etc.The high light high abrasion of this series products, but product price is high, the UV coating oil is prone to infiltrate the middle level of paper fibre in addition, causes the ultraviolet light polymerization weak effect even can not solidify, and have certain toxicity, so can not be used for the Lacquer finish of packages printings such as food and medicine industry.
2, pure dissolubility coating oil: mainly be as solvent synthetic vinyl resin with alcohol; Products characteristics is that cost is low, glossiness is high; But this series products has a large amount of alcohol volatilizations when last machine; There are very big problem in environment, production safety etc., and the wear-resisting wiping property of paper of printing in addition behind the Lacquer finish is poor.
3, oiliness coating oil: this series products is owing to there is the volatilization of a large amount of benzene kind solvent in use, and not environmental protection and have a strong impact on personnel safety seldom has manufacturer production now on the market, almost eliminated by market.
4, the multiple film of BOPP: the BOPP film is to be compounded on the paper printing ink through glue, has the characteristic of high abrasion Gao Guang, but is not very difficult the recovery and biological degradation of paper after environmentally friendly machine is used.
More than these Lacquer finish products all have environmental protection and safety-problems; And along with the development of society; Human protection consciousness to living environment also improves constantly, and environmental protection has been not only economic problems, but is related to the big problem of whole human survival; Print product is infiltration human lives one of product the most widely, is paid close attention to by society and people in the nature of things.In the printing packaging industry, increased the requirement and the restriction condition of aspects such as many health, environmental protection, labour protection in recent years gradually, particularly more strict to the requirement of food product pack printing, thus meet the requirement of international hygiene standard.Under this megatrend, effort development and application pollution-free, non-harmful " green " material is imperative.The water-based coating oil is a luminescent material on developed country's novel printing of falling over each other to research and develop in recent years; Receive the printing people's of circle attention day by day; It is as a kind of emerging environmental protection printing material; Its feature of environmental protection, security are self-evident, are environmental protection and energy saving the most in the above Lacquer finish product, but aqueous product because of glossiness friction property etc. not as other series products; On market, being not easy to promote and use, is developing aqueous product market, response national environmental protection policy and the key that is beneficial to personnel safety so strengthen the quality of its research and development dynamics, raising water-based Lacquer finish product.
Summary of the invention
The present invention is just in order to overcome above-mentioned deficiency; Technical problem to be solved provides a kind of water-based printing coating oil, not only environmental protection of this product, nontoxic, and have transparency height, glossiness height; Good, the anti-cut of scratch-resistant performance, film forming speed is fast, drying characteristic rapidly.
The technical problem that the present invention also will solve provides the method for manufacture of above-mentioned high light high abrasion water-based coating oil.
