Description
Technical field
The present invention relates to a kind of primary coat dope for treating vacuum aluminum plating paper, be used for the surface treatment of beer mark body paper.
Background technology
Vacuum aluminium-plated paper is the low novel package paper that also can replace clad aluminum foil of a kind of cost.Its use can make the consumption of metallic aluminium reduce greatly.Because the vacuum aluminum-coated body paper of aluminizing (being white glazed paper) surface gloss and smoothness to use had relatively high expectations, thereby must handle the body paper surface of aluminizing before aluminizing.Promptly be coated with one deck dope with coating machine, and then send in the vacuum coating equipment and aluminize on its surface.The purpose of coating one deck dope is to solve the uneven problem of paper, improves surface gloss and smoothness, is convenient to vacuum aluminum-coated.
What vacuum aluminium-plated paper was produced employed coating for paper employing at present mainly is solvent based coating, and wherein base-material is rosin, dibutyl ester, polyvinyl butyral, dimethylbenzene etc.With organic matters such as dimethylbenzene is solvent, and the toxicity smell is big, be unfavorable for safety in production and improve working conditions, and causes environmental pollution easily.
Chinese patent CN1944790A discloses a kind of preparation method of water base material for treating vacuum aluminum plated paper, film have excellent in water resistance, high glaze, good adhesive force, but ABRASION RESISTANCE, alkali resistance are poor.
Summary of the invention
The technical issues that need to address of the present invention are to propose a kind of primary coat dope for treating vacuum aluminum plating paper, to overcome the defective that prior art exists.
Primary coat dope for treating vacuum aluminum plating paper of the present invention is characterized in that, each component and parts by weight are as follows:
