Fiberboard with PVC Coated Plastic Research

Abstract

PVC film facing material has the real wood grain feeling, high wear resistance strength, soft gloss and widely used in wooden furniture surface decoration [. But PVC film and plank have low degree of adhesive; water will open in bubble shortcomings. And butyl acrylic, vinyl acetate copolymer emulsion and have good adhesive sex and peel strength, and it has better cohesion[.This article describes the modified acrylic adhesive vinyl acetate synthesis methods and performance characteristics that affect the performance of some of the major factors, namely raw material ratio, the amount of initiator, polymerization temperature, add water, put forward various factors on product performance cause and effect, and how to improve product performance were discussed. Analysis of the response characteristics of acrylic ester, acrylic acid ester described the main components of raw materials and application of several adhesive, tells today of Propylene. Ester adhesive research trends and research progress. In addition to the acryl ate modified vinyl acetate adhesive preparation and distribution of each group than to its solid content, initial viscosity, viscosity can be held, 180-degree peel strength of the main physical properties[. With the change in the distribution ratio of each group, the physical properties of its corresponding change took place, after joining EHA modified acrylic adhesive vinyl acetate also increased the initial viscosity. With the change in component modified vinyl acetate acrylic adhesive solid content and viscosity are held to change[.Idea vinyl acetate adhesive properties of the impact of factors related to the quality of acrylic acid, the ratio of butyl acryl ate and ethyl acetate, PVA's quality[. The results show that when the initiator was ammonium per sulfate (APS), the acrylic acid quality is 4, the ratio of butyl acryl ate and ethyl acetate 30:70, PVA modified by a mass of 8 180 vinyl adhesive peel strength largest, best quality plastic. Preparation of rubber modified vinyl acetate preferably 180 ° peel strength, holding the maximum viscosity, the measured test results of the best.Key words: Acryl ate; acryl ate modified vinyl acetate adhesives; holding viscous energy; 180 ° peel strength;
