Abstract
The invention provides a crossing linking modified PVA environment-friendly watertight label adhesive and a manufacture method thereof. The invention is characterized in that the adhesive is obtained by reaction among water, polyvinyl alcohol PVA, emulsified silicone oil, hydrochloric acid, formaldehyde, sodium hydroxide, melamine, carbamide, glyoxal, aziridine and Kathon according to a certain mixture ratio, a certain sequence and requirements. The label adhesive manufactured by using the invention has the advantages of low cost, good water resisting property, no release of hazardous materials and environment protection, and can meet the requirements of the prior bottled product high-speed production line.
Description
Technical field
The present invention relates to adhesive area, is a kind of cross linking modified PVA environment-friendly watertight label adhesive and method for making thereof that a kind of bottled product is used specifically.
Background technology
Adhesive for labels is a kind of widely used tackiness agent, is mainly used in industries such as food, medicine, agricultural, chemistry, satisfies the label of product such as bottled, canned and pastes needs.Along with the fast development of drink industry, drink packing class and production rate all are greatly improved.Particularly beer industry had both required adhesive for labels to satisfy different production rate needs, also required to have good water tolerance, can not fall mark more than 72 hours by stable existence in frozen water; And, after useless bottle secondary recovery, in 70-80 ℃ alkaline water, be easy to the cleaning of label.At present, label is pasted and is mainly contained composite modified class of casein class, starch based and polyvinyl alcohol (PVA) and polyvinyl alcohol (PVA) modification class etc. with tackiness agent.(Chinese patent: 97121755.6) cost is lower, but does not have water tolerance for the composite modified class of starch and polyvinyl alcohol; 96100825.3) and monomer-grafted class such as polyvinyl alcohol and vinylformic acid (Chinese patent: ZL200410060505.3), certain water-fast effect is arranged, but several hrs will fall mark polyvinyl alcohol (PVA) modification class is divided polyvinyl alcohol formal class Chinese patent:; Casein type tackiness agent is a kind of comparison equilibrated tackiness agent that has both good initial stage binding property, water tolerance and neutralizing treatment, because domestic casein food grade price is higher, add and lack relevant production technology, so the beer production line of domestic middle and high speed reaches the producer as tinsel label glue, casein glue (the German Patent: DE4126074A1), per ton that most dependence on import Henkel KGaA company produces up to more than 18000 yuan.Although several years ago domestic units are studied casein glue according to the characteristics of Chinese casein food grade, and some progress and achievement (Chinese patents: ZL99105486.5) have preferably been obtained.But in recent years, raising along with people's living standard, people are also more and more to the attention of milk and milk-product, directly cause rapidly rising violently of casein food grade price, about 70000 yuan per ton of existing market valency, but also on the rise causes that the cost of casein glue is per ton to reach more than 1.4 ten thousand yuan, therefore some beer producers are also just hung back to casein glue, cause applying of this product to be under some influence.Reducing cost becomes the key issue of being badly in need of solution.
Summary of the invention
At the problems referred to above, purpose of the present invention is developed a kind of excellent property exactly, a kind of cross linking modified PVA environment-friendly watertight label adhesive and method for making thereof with low cost.
