Description
Affiliated technical field
The present invention relates to a kind of coating and intercept polyvinyl alcohol coating and preparation method thereof, belong to the novel environment friendly polymeric material field with water-resisting type.
Background technology
In recent years, along with people increase food safety requirements day by day, the high barrier wrapping material of good environmental adaptability are received just day by day the fervent concern of research field and industrial community.The polyvinylidene dichloride that occupies most of high barrier coating market at present is because of containing chlorine; Environmental problem day by day highlights; Polyvinyl alcohol has very high blocking oxygen performance; And polyvinyl alcohol environmentally safe; Only remaining carbonic acid gas and water after the burning are as a kind of ideal high-barrier packaging material and popular.But along with the further investigation to polyvinyl alcohol, find its poor water resistance, promptly after the coating, polyethylene coating is easy to the moisture absorption in environment, have a strong impact on coated film outward appearance and barrier property thereof.And coating blocking oxygen performance is subjected to ambient moisture to influence weakness such as big, limits its further application.For seeking breakthrough, the research report to polyvinyl alcohol modification is a lot of both at home and abroad at present, but effect is all optimistic not to the utmost.Such as, on polyethylene coating, cover another layer coating or mix another kind of coating solving its water tolerance problem, but cost improves greatly and influences coated film blocking oxygen performance; Some modified polyvinyl alcohols of existing market, the film outward appearance is undesirable and moisture absorption phenomenon is serious though its coated film water tolerance improves.
Summary of the invention
In order to improve the water tolerance of polyvinyl alcohol, improve the susceptibility of coating to ambient moisture, divide the sealing part of the hydroxyl in the clamp mechanism long-chain with chemical process with polyvinyl alcohol, reduce it and water carries out affinity interaction.The present invention is when solving a Water-Resistance of PVA difficult problem; Through adding nano imvite in polyvinyl alcohol coating; Nano imvite is dispersed in the polyethylene coating with laminate structure behind this modified paint of coating; Hinder the circulation diffusion of gases such as oxygen, with the oxygen resistance of further raising polyvinyl alcohol coated film.This coating is stable, coating adaptability is good, technology is simple and suitable suitability for industrialized production.
The present invention provides a kind of coating to intercept polyvinyl alcohol coating with water tolerance, and this coating is become by the preparation of raw material that contains following weight content: polyvinyl alcohol 5～7%, nano imvite 0.01～0.05%, aminoresin 0.5～1%, catalyzer 0.01～0.3%, defoamer 0.01～0.1%, deionized water 91～94%.
The described polyvinyl alcohol polymerization degree is 1700, and alcoholysis degree is 99%.
