Description
The application is application number is 201210019968.X, the applying date: on 01 21st, 2012, and denomination of invention is the divisional application of " a kind of recovery and treatment method of prepreg cutting edge material and reuse method " patent application.
Technical field
The present invention relates to a kind of reuse method of prepreg cutting edge material.
Background technology
Along with the develop rapidly of science and technology, the scale of electronic industry suitability for industrialized production constantly expands.Developing rapidly especially in recent years along with epoxy resin industry, the continuous increase of the market demand, has driven the diversified development of its downstream industry, and a new development peak period appears in laminate industry, and plurality of layers pressing plate manufacturing enterprise constantly expands production lifting production capacity.
At present, the production procedure of domestic laminate mainly comprises: the main flow such as the preparation of the preparation of adhesive, the preparation of prepreg, lamination material and pressing.Wherein in the preparation process of prepreg, the edge of common glass fabric impregnant is after technological process, weft yarn end is owing to being infiltrated by adhesive and toasting, multiply weft yarn adhesion heat solidity adhesive, form tiny comparatively hard branch, not only reduce prepreg presentation quality, the operation of subsequent handling is impacted simultaneously.
At present, the enterprise that automaticity is higher often adopts high-pressure hot air process, but most of manufacturing enterprise is due to production technology backwardness relative to equipment, and the general cutter that adopts cuts process, therefore a large amount of cutting edge material is created, because the reason of profile is commonly called as " caterpillar ".These cutting edge material are owing to being stained with the adhesives such as epoxy resin, and self not easily decomposes, and adhesive composition machinery easily deliquescing stick to equipment surface after being heated during mechanical treatment, very large to equipment loss.At present good processing mode is not also had for above-mentioned cutting edge material, if piled up in a large number, easily pollutes environment.
