Description
Technical field
The invention belongs to binding agent field, particularly relate to a kind of packing hot-fusible glue of high cohesive force.
Background technology
EVA hot-melt adhesive is formulated by EVA resin, tackifier, softening agent, antioxidant, filler etc.In society now, EVA hot-melt adhesive applied range, consumption are maximum.It has excellent adhesiveproperties, nearly all has hot sticky relay to various material; Excellent electric property; And its melt viscosity is low, applying glue is convenient; With the feature such as the consistency of other Synergist S-421 95s is good.EVA hot-melt adhesive has been widely used in shaping, many fields such as automobile and building materials of the bookbinding of books, bonding, ceramic etc. the reparation of the packaging, plastics etc. of food, mounting, clothes and shoes and hats.Because EVA resin is a kind of thermoplastic resin, high and low temperature resistance is limited, softening temperature is low, and main auxiliary material tackifier are all the polymkeric substance of molecular weight mostly, just play reduction melt viscosity, improve the effect of wetting ability and initial cohesiveness, itself is high-low temperature resistant not, causes the shortcoming of EVA hot-melt adhesive not high-low temperature resistant; Simultaneously also there is lower, the not resistance to fatty oil of adhesiveproperties, easily produce skinning and be not suitable for the shortcomings such as big area coating is bonding in EVA hot-melt adhesive.
At present, along with developing rapidly of PET industry, waste PET quantity also increases thereupon, thus brings serious pollution to environment.How to recycle waste PET, become one of focus of research at present.PET reclaims and mainly comprises physiochemical mutagens and chemical recovery two kinds of methods, physiochemical mutagens method cost is lower, but after physiochemical mutagens, the Mr(relative molecular mass of material) and limiting viscosity all reduce, the PET product be made up of physiochemical mutagens material can not be reused this way and recycle; Chemical recovery makes PET generate micromolecular compound by chemical reaction, and the performance of this method products therefrom is more excellent.Chemical recovery technique can be divided into hydrolysis, ammonia solution and alcoholysis etc. (wherein alcoholysis process is chemical recovery technique relatively more conventional at present), as Pereira etc. utilizes the polyester of degraded to make tensio-active agent.
