1. the compound guarantor of spun glass nascent state preimpregnation is technological by force, it is characterized in that discover according to me:

  • spun glass is 4 hours by the average period that nascent state is converted to operating conditions;

    Become spun glass from the glass melting wire drawing and begin within 4 hours, be the nascent state survival time, in spun glass nascent state survival time;

    Spun glass keeps the characteristic of nascent state basically;

    tensile strength still is nascent state intensity;

    Considerable change does not take place, and fiberglass surfacing still has negative potential, has stronger adsorptivity and reactivity;

    Can adsorb polar functional group and form firm chemical bond;

    Matrix resin is connect by on fiberglass surfacing, form influence and corrosion that stable chemical state is resisted outside atmosphere and water, keep the intensity of nascent state.According to above discovery and principle;

    As long as in spun glass nascent state survival time, implement and accomplish the preimpregnation coating of matrix resin to newborn spun glass;

    Utilize the adsorptivity and the reactivity of nascent state fiberglass surfacing;

    Add the positively charged ion organosilane of 0.1%-5% with the modified resin of positively charged polar functional group or in common matrix resin, be coated in newborn fiberglass surfacing, make the matrix resin bonding or connect skill on fiberglass surfacing;

    Form a kind of stable chemical state, just can keep the higher-strength of spun glass nascent state.
