As preferably, described mould oil is secondary facility oil.
As preferably, described promoter is T-8A cobalt iso-octoate, and T-8A cobalt iso-octoate, for resin, has and well urges dryness matter.
As preferably, described curing agent is methyl ethyl ketone peroxide, and methyl ethyl ketone peroxide is easy to resin-bonded, and both cooperations can form the solidfied material of stable in properties.
The present invention also provides a kind of manufacture method of above-mentioned grid, and its concrete steps are as follows:
1) with platform scale, get appropriate TM191RS unsaturated polyester resin in mixer, by ratio of quality and the number of copies, measure appropriate aluminium hydroxide, fire retardant, mould oil, pigment paste and promoter, and joined in TM191RS unsaturated polyester resin, even by mechanical agitation, mixing time is not less than 30 minutes;
2) according to operating environment, measure appropriate curing agent and add the above-mentioned material preparing, and stir, mixing time is not less than 5 minutes;
3) the above-mentioned raw material preparing is added in mould, make raw material be uniformly distributed in mould as far as possible;
4) with special guide instrument by roving by radially, broadwise arrange row in mould, every thread tube is worn 3 rovings, row's layer number is as follows: H=38mm, through the each 13-14 layer of broadwise, H=25mm, through the each 7-8 layer of broadwise, through broadwise, often sequence after one deck, yarn is compressed with special pressing plate, make the abundant impregnated with resin of yarn, then carry out lower one deck row yarn, until reach the regulation number of plies;
5), after roving arranges, opening mold heating system, when temperature indicator displays temperature is during at 100 ℃-180 ℃, continues insulation 20-30 minute, then opens cold water switch, after cooling 30-45 minute, to treat the demoulding;
6) with 4 jack, be placed under the back timber of mould both sides, shake jack by product from mold ejection.
Beneficial effect of the present invention is: this glass fibre grid replaces pitch with the coating raw material of newly joining, make grid high temperature resistant, there is anti-flammability, and strengthen with the tight ness rating on road surface, physicochemical properties are more stable, longer service life, maintenance, the bridge road surface that can be widely used in old cement pavement, airfield runway strengthen the engineering fields such as processing.
