Abstract
This invention relates to a method for producing composite pipeline brackets by hot-pressing molding. The composite pipeline brackets are produced from thermosetting resin, glass fibers, glass cloth, filler, and flame retardant. The composite pipeline brackets can be used as a substitute for metal pipeline brackets, and have such advantages as no magnetism, high strength, high salt-mist corrosion resistance, no toxicity, good heat insulation, no damage to pipelines, low energy consumption, low equipment investment, low cost and high cost performance.
Description
Technical field
The present invention relates to a kind of manufacture method that adopts matrix material to make pipe support and this pipe support.
Background technology
For a long time, public utilities and industrial pipeline adopt the pipe support of metal, and these metallic conduit supports are normally by iron and steel or aluminum alloy rolled required section bar, welding or assembled with fastening piece after the cutting.These conventional metals support production process energy consumptions are big, operation is many, the cycle is long.And under many occasions, for example underground works, chemical enterprise, rainy humidity or coastal salt mist environment, the iron and steel support gets rusty easily, corrodes, and reduce work-ing life greatly, even adopt processing such as outer painting or galvanizing, still can not thoroughly solve etching problem.What " multipurpose steel and plastic composite material support " (patent No. 96114172.7) adopted is that thermoplastics and metal extruding form, be shaped as double-deck tubing or square type, skin is plastics, internal layer is a thin-wall metal pipe, and it has corrosion resistant advantage, but because its intensity is low, toughness is big, flexural strength only is 40MPa, and is yielding, and is not suitable for pipe support; Simultaneously its adopts steel as liner, has magnetic, is not suitable for using under the non-magnetic condition requiring.
Summary of the invention
Purpose of the present invention be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of nonmagnetic, corrosion-resistant, resistivity against fire is good, good rigidly, heat insulating ability are good, the pipe holder made from composite material and the manufacture method thereof of low cost of manufacture.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of pipe holder made from composite material is characterized in that, this pipe support is made by the fiber reinforcement duroplastic moulding materials; Described fiber reinforcement duroplastic moulding materials comprises thermosetting resin, glass fibre, woven fiber glass, filler and fire retardant, is by weight percentage: thermosetting resin 20～40, glass fibre 5～40, woven fiber glass 10～30, filler 20～60, fire retardant 5～30.
Described thermosetting resin is a unsaturated polyester resin; Described glass fibre is 5mm staple fibre or continuous fiber; Described woven fiber glass is alkali-free glass cloth or glass fibre non-woven, and described filler comprises one or more in lime carbonate, talcum powder, kaolin, aluminium hydroxide, the silicon powder, and described fire retardant is hibbsite or phosphorous, halogen-containing flame retardant.

Described fiber reinforcement duroplastic moulding materials also can comprise releasing agent, is 0.5～2 by weight percentage.
Described pipe support is independent moulding pipe support or combined pipe support.
Described pipe support is used to support DN80 and following pipeline.
A kind of manufacture method of pipe holder made from composite material is characterized in that, this method is starting material with the fiber reinforcement duroplastic moulding materials, adopts hot-forming manufactured; The weight percent of described fiber reinforcement duroplastic moulding materials consists of: thermosetting resin 20～40, glass fibre 5～40, woven fiber glass 10～30, filler 20～60, fire retardant 5～30; Described hot pressing formation process is: at first the fiber reinforcement duroplastic moulding materials is mixed with Preblend by above-mentioned weight percent composition, adopt the pipe support mould of closure up and down of band heating and temperature regulating device then, and it is installed on the press, when the mould temperature reaches 100～170 ℃, drop into the Preblend of fiber reinforcement duroplastic moulding materials rapidly, pressure-maintaining and heat-preservation solidified 5～20 minutes under 5～25MPa, and depanning can obtain desired product then.
Support of the present invention is to be raw material with the fiber reinforcement duroplastic moulding materials, is prefabricated into prepreg earlier, adopts hot pressing formation process to be prepared from again.Prepreg can be made into bulk (BMC), sheet (SMC), thick shape (TMC) or high-strength (HMC) etc.
Support of the present invention is because material adopts the glass-fiber reinforced thermo-setting moulding compound, and is added with fire retardant in the material, so (modulus in flexure can reach 12 * 10 to its rigidity height
3About MPa), indeformable, corrosion-resistant, resistivity against fire is good, nontoxic, good insulating, heat insulating ability are good, and its processing and manufacturing energy consumption is low, facility investment is less, cost is low, P/C is than high.Support of the present invention has overcome the existing problem of through metal.Table 1 is that the performance of support of the present invention and existing metallic conduit support compares.
