Description
The application is 201510414989.5 for application number, and the applying date is on July 15th, 2015, and denomination of invention is the divisional application of a kind of hydroxypropylation treated starch and preparation method thereof, glass fiber infiltration agent
Technical field
The present invention relates to fiberglass surfacing processing technology field, be specifically related to a kind of glass fiber infiltration agent adding treated starch.
Background technology
Hydroxypropylated starch is a kind of important chemically modified starch, after its modification, the stability replacing ehter bond due to etherification starch is high, and hydroxypropyl has wetting ability, can weaken the internal hydrogen bonding strength of starch granules structure, it is made to be easy to expand, gelatinization is easy, sticks with paste liquid transparent, good fluidity, retrogradation is weak, and stability is high.Hydroxypropyl corn starch all can be applied in industries such as food, printing, weaving, printing and dyeing, washing composition, papermaking, medicine, metallurgy, petroleum drillings.Hydroxypropyl corn starch, in glass fibre preparation process, is used as the film former component for the treatment of compound usually, for the surface treatment of glass fibre.
In glass fiber wire-drawing process, need in fiberglass surfacing coating a kind of based on the special surface treating agent of the heterogeneous structure of organism milk sap or solution.This applicator can lubrication protection fiberglass surfacing effectively; again can by hundreds of so that thousands of glass monofilament integrated a branch of; the condition of surface of glass fibre can also be changed; so not only meet the requirement to glass precursor performance in subsequent processing operations, and glass fibre and the combination of high molecular polymer be enhanced can also be promoted in the composite.These organic coat things are referred to as the glass fiber infiltration agent adding treated starch.Under normal circumstances, treating compound is made up of many materials such as membrane-forming agent, coupling agent, static inhibitor, membrane-forming agent is the key ingredient for the treatment of compound, not only boundling, cohesive action are played to precursor, also determine the processing characteristics of glass when glass filament reinforced plastics is shaping, also determine the film-forming properties for the treatment of compound and the avidity to fiberglass surfacing simultaneously, the treating compound that the membrane-forming agent of excellent performance is made can form high, soft, the wear-resisting film of intensity at fiber surface, and combines together with fiberglass surfacing.
The treating compound used the earliest is paraffin sizing material, and this treating compound not easily moves back solution, but the laking agent warm wash difficulty in formula, make the glass fibre made turn to be yellow or produce obvious brown stripes, reduce product specification.Afterwards, along with the development of fiberglass surfacing treatment technology, engender and adopt starch as treating compound.But unmodified starch is because gelatinization point is high, viscosity is uneven, film-forming properties is poor, the shortcomings such as character is unstable cannot use as membrane-forming agent, and the starch that hydroxypropylation is modified, due to the distinctive wetting ability of hydroxypropyl, improve the performance of starch as membrane-forming agent, and hydroxypropylation degree is higher, its film-forming properties and better with the fusion performance of fiberglass surfacing.
But, crystalline texture due to starch is unfavorable for infiltration and the reaction of chemical reagent, especially the efficiency of etherification reaction is extremely low, therefore increasing research focuses on the preparation feedback efficiency and hydroxypropylation degree aspect that improve hydroxypropylation treated starch at present, a kind of preparation method of starch-type membrane-forming agent of the glass fiber infiltration agent for adding treated starch is disclosed as Chinese patent CN102304188A, adopt and first enzymolysis is carried out to starch, add the preparation method that etherifying reagent carries out hydroxypropylation again, need heating starch gelatinization before enzymolysis in the method, the starch very thickness of gelatinization, be unfavorable for suitability for industrialized production.Even if viscosity reduces after enzymolysis, the reaction efficiency that still there is starch and etherifying reagent is low, the defect that hydroxypropylation degree is low.
