Abstract
The present invention is sandwiched foamed heat insulating plate of phenolic resin GRP produced with mixed phenols extracted from the leftover of oil refinery, formaldehyde, alkali liquor, ammonia water, melamine, urea, starch, etc through reaction, mixing with glass fiber or asbestos fiber to form phenolic resin GRP, and other steps. The sandwiched foamed heat insulating plate of phenolic resin GRP has light weight, high strength, high rigidity, high weather resistance and other advantages.
Description
Technical field:
The present invention is a kind of sandwich foam heat-insulating board directly synthesized from bakelite fiber glass resin of using, affiliated decorative building material-warming plate.Do not burn when meeting fire, smokelessly do not have poison gas, the intensity height, in light weight, quality is good, heat insulating materials such as water-tight corrosion-proof.
Background technology:
Along with growth in the living standard, industrial expansion, people are more and more darker to the understanding of the importance of problems such as safety, lightweight, application life, expense and destruction value.In order to overcome existing warming plate, the bonding cystosepiment of magnesium cement glass steel plate is arranged, the meeting oxidation, intensity is low, and is not anticorrosion, the manufacturing process complexity; Glass epoxy and cystosepiment that useful epoxy resin, unsaturated polyester resin etc. are made are bonding, complex process, and the cost height, flame retardant effect is poor, and has cigarette that poison gas is arranged, and safety is exceeded standard.
We develop the synthetic sandwich foam heat-insulating board of phenolic fiberglass reinforced plastics, it is with reactions such as the mixed phenol of extractions such as the leftover bits and pieces of oil refinery and formaldehyde, mix synthetic phenolic fiberglass reinforced plastics thermosetting resin again with glass fiber etc., be used for making the glass fiber reinforced plastic surface layer or the adhesive-layer of warming plate.Can be used for roofing interlayer heat-insulating leakage-proofing, indoor furred ceiling insulation, sound insulation, air-conditioning duct, freezer, aviation, locomotive, long-span roofing plate, interim office, shop, market, sentry box, container house etc.This sheet material is respectively that, magnesium cement synthetic glass steel synthetic with bakelite fiber glass resin etc. made high-strength sandwich flame-retardant expanded light weight board, have light weight, intensity height, good rigidity, anti-aging, do not go mouldy, when meeting fire burns smokeless no poison gas to people's comparison safety and environmental protection, waterproof anti-corrosion engineering, the sound insulation of antiultraviolet thermal insulation, shock resistance is good, installation, maintenance, cleaning convenient, can use outstanding advantage more in adverse circumstances such as 200 ℃ of high temperature, low cold-180 ℃.
Summary of the invention:
Sandwich foam heat-insulating board directly synthesized from bakelite fiber glass resin of the present invention will solve its technical problem: at first be synthetic phenolic fiberglass reinforced plastics thermosetting resin, the synthetic of it is mixed phenol 30-50%, formaldehyde 50-70%, liquid caustic soda (NaOH) 2-8%, ammoniacal liquor 1-4%.Start agitator, add earlier formaldehyde 50-70%, add liquid caustic soda 2-8% simultaneously, ammoniacal liquor 1-4%, stir 2min after, in stirring, add mixed phenol 30-50%, stir 2min again after, be determined as: ph=8-9.In 10-20min, heat up 85 ℃-90 ℃ then and stop to heat autoreaction backflow 60-90min.Its cloud temperature of test in 30 ℃ of clear water has tangible little white pearl heavy fixed, stops reaction, the hydrochloric acid with 10%, under agitation in and ph=7.Dehydration (or vacuum dehydration) then, dehydration requires solid content to reach 86%-90%, continuing to throw in 2-8% such as melamine, urea, starch (absorbing free aldehyde) stirs well even, and then throw in glass fiber, each 10-30% of asbestos fiber stirs well the cooling barrelling of even back, finished cheap and good-quality phenolic fiberglass reinforced plastics thermosetting resin, can be stand-by after one day.
By the phenolic fiberglass reinforced plastics thermosetting resin, making the phenolic fiberglass reinforced plastics sandwich foam heat-insulating board again, is to implement like this:
Select the frothing foam plate: select the flame-retardant expanded plate that has had on the market for use, density is 10-30kg/m3, can use flame-retardant expanded plates such as phenolic aldehyde, polyamine fat, polystyrene, polyvinyl chloride any one, thickness of slab is surface plate or the corrugated sheet of 1-5cm, also can own produce convenient the use with foaming machine.With the flame-retardant expanded plate of polystyrene is example:
1, the demand of answering produces the phenolic fiberglass reinforced plastics sandwich foam heat-insulating board of different-thickness and intensity, size with the thickness and the plate of needed plate, be placed on the machine of making board, with bakelite fiber glass resin and curing compound (acids curing compound such as hydrochloric acid) ratio be again: 100: 4-10, after the adding mixing head mixes, start machine of making board, cystosepiment was by traction before this, through covering fiber/glass fiber cloth in one deck, when mixing head, the beginning blowing is continued plate is moved on on the Lacquer finish roll-in platform by the traction transmission with the even showering of resin onboard again, through covering the polyester cloth roll-in then that Lacquer finish is used, make the plank surface layer evenly smooth, and then move on the curing station, normal temperature cure or be heating and curing all can, the curing and demolding cutting, just directly once having synthesized high strength phenolic fiberglass reinforced plastics surface-brightening does not have the cheap and good-quality sandwich foam heat-insulating board that gas is shouted.
2, do adhesive with bakelite fiber glass resin, FRIM (magnesium cement glass steel) plate and flame-retardant expanded foamed plate adhesion.Cost is low, the intensity height, and the waterproof mildew-resistant is nontoxic, advantages such as long service life.Concrete operations are: with bakelite fiber glass resin, gypsum, sulphur aluminic acid cement etc. and hydrochloric acid, mixing ratio is: 100: 4-10: 2-8, stir well even the mixing at the machine of making board mixing head, by the traction transmission when arriving mixing head, with the viscose glue that mixes automatically evenly showering on the cystosepiment or even showering on the unorganic glass steel plate, closely knit through roll-in again, move to curing room, normal temperature cure or be heating and curing all can.Solidify the back cutting, detect, pack.
