Abstract
The present invention discloses one kind one manhole cover seat of composite material and its making process. The cover seat has casing made of composite material, coated with polymer material in the inside wall, and with embedded rib ring and stuffing. The composite material has relatively high impact-resisting toughness and high wear resistance and may be glass fiber reinforced unsaturated polyester resin or reinforced polypropylene material. The making process may be a hot molding or injecting one. The manhole cover seat of composite material is wear resistant, impact resistant and compression resistant, and has simple production process, long service life and low cost.
Description
One, affiliated technical field
The present invention relates to a kind of polymer composite material manhole cover base and manufacture method thereof, refer in particular to glass and strengthen unsaturated polyester resin moulding compound or RPP material composite material manhole cover base and manufacture method thereof.
Two, background technology
Polymer composite material manhole cover is because it is in light weight, no recovery value and more and more be subjected to the favor in market.But since this product also have a lot of shortcomings as: composite material base because of compressive strength and poor impact toughness, roll to carry through road roller and can occur collapsing limit or phenomenon of rupture after executing with vehicle, influenced the application life of complete well lid.
Three, summary of the invention
The purpose of this invention is to provide a kind of polymer composite material manhole cover base and manufacture method thereof.Wear-resisting, the shock-resistant and compression of polymer composite material manhole cover base.The product manufacturing is simple, improves application life, and with low cost.
For achieving the above object, the solution that the present invention takes is: a kind of polymer composite material manhole cover base, and the material shell inwall scribbles macromolecule layer, and material shell is put into steel ring and is filled with filler.
Described filler is the mixture of cement, skeleton material, sand, water.
Described filler is the mixture of cement, skeleton material, sand, water, steel fibre.
A kind of manufacture method of above-mentioned polymer composite material manhole cover base, strengthening the unsaturated polyester resin moulding compound with glass is raw material, by punching block heating high-pressure molded composite material shell, the mould pressing process condition is: temperature is 140 ± 30 ℃, and pressure is 200～500kg/cm
2Hardening time 1～3min, the material shell inwall is handled through molecular layer, this material shell inversion is kept flat, put into steel ring therein, pour in the material shell slurry of the mixture of cement, skeleton material, sand, water into the hand ramming gel solidification, it is real to stroke concora crush with cement mortar again, and through maintenance get final product polymer composite material manhole cover base.
A kind of manufacture method of above-mentioned polymer composite material manhole cover base, with the RPP is that raw material is made material shell by injection moulding, the material shell inwall is handled through molecular layer, put into steel ring therein, the slurry of cement, skeleton material, sand, water, steel fibre is joined material shell, steel fibre accounts for 5%～10% of filler weight, and tamping is scraped and flattened, and promptly gets through maintenance and can get polymer composite material manhole cover base.
Shell is that glass strengthens unsaturated polyester resin moulding compound or reinforced polypropylene compound material, the material shell inwall is handled to improve concrete and composite material adhesive strength through molecular layer, and material shell inside is enriched by cement concrete or steel fiber feinforced cement concrete filler.Because composite material has wear-resisting, shock-resistant effect, and filler plays the compressive strength that improves the well seat, makes the upper surface of well seat and bearing surface not collapse the limit phenomenon, has improved product application life.The well seat of producing with these two kinds of methods with test after well lid cooperates, can bear the trial load of 50T and do not ftracture, it is carried out finding that from 3 meters high free falling impact tests the well seats do not rupture or ftracture.Use this two kinds of method productions, the product manufacturing is simple, and with low cost.
