Abstract
The invention discloses a method for preparing a high-abrasion-resistant glass fiber reinforced plastic sand inclusion pipeline. The method comprises the steps that carbon fibers and glass fibers are woven into a surfacing mat in a mixed mode and then the surfacing mat is soaked in a silance coupling agent solution for surface treatment; the surfacing mat is dried; unsaturated polyester resin is soaked in the dried surfacing mat and the surfacing mat is wound on the surface of a pipeline mold in a certain length so that a lining layer can be formed in a solidified mode; a structure layer and an outer protecting layer are manufactured on the lining layer in a traditional mode. According to the method, the lining layer is manufactured by the surfacing mat woven by the carbon fibers and the glass fibers in a mixed mode, the abrasive resistance, the corrosion resistance, the ageing resistance and the specific strength of the lining layer are improved through the characteristics of the carbon fibers, and the mechanical performance of the lining layer is adjusted by means of change of the proportion of the carbon fibers and the glass fibers, so that the comprehensive mechanical performance of the pipeline is improved, and therefore the service life of the pipeline is prolonged and the method is wide in application prospect in the fields of an oil field, machinery, the chemical industry, ships and the like with the requirements for the high-abrasive resistance.
Description
Technical field
The invention belongs to technical field of composite materials, particularly relate to a kind of preparation method of high abrasion glass steel clamp sand pipeline.
Background technique
glass fiber reinforced plastic sand-inclusion pipeline is a kind ofly to using unsaturated polyester resin as body material, the novel glass reinforced plastics composite pipeline that glass fibre and goods thereof are made as packing material as reinforcing material and silica sand, it is the high-tech product of national mandatory popularization at present, have corrosion-resistant, anti-aging and high-strength light, antiseepage, nontoxic and smooth surface, the conveying liquid resistance is little, energy assure feed water water quality, the characteristics such as anti-chemistry and electro erosion, and can reduce engineering cost, have simultaneously easy for installation, long service life, comprehensive cost is moderate, simple to operate, the characteristics such as maintenance cost is low, these superior performances have overcome tubing at present commonly used such as steel pipe, some drawbacks that reinforcing bar silicone tube and cement pipe etc. exist, thereby become its alternative, it is a kind of flexible composite pipeline of applying gradually both at home and abroad at present.Glass fiber reinforced plastic sand-inclusion pipeline structure commonly used is divided into three layers: inside liner, construction layer and external protection.Present this pipeline adopts the wet method preparation usually; at first this preparation method is soaked with the glass fiber bundle (also claiming glass yarn) of unsaturated polyester resin and solidifies and make inside liner on the surface of pipe mould is wound around; then the glass fibre gauze belt that surface is covered with to the damp sand bar of being made by silica sand and unsaturated polyester resin is wrapped in the surface of inside liner and solidifies and make construction layer, finally on the surface of construction layer, adopts external chiasma hoop mode to be wound around the glass fiber bundle that is soaked with unsaturated polyester resin and solidifies and make external protection.Although this glass fiber reinforced plastic sand-inclusion pipeline has above-mentioned advantage, but still come with some shortcomings, wherein the most obvious shortcoming is that the wear resistance of inside liner is slightly poor, and main cause is not to be very good glass fibre because inside liner only contains wear resistance, so affected the working life of this pipeline.
Carbon fiber is high by carbon content, and the artificial chemical fibre of not melting in heat treatment process adopts the techniques such as thermally-stabilised oxidation processes, carbonization treatment and graphitizing and makes.Its profile has significant anisotropy, along fiber direction, shows very high intensity, and carbon fiber proportion is little, therefore has very high specific strength.Simultaneously carbon fiber also has the excellent specific properties such as high temperature resistant, rub resistance, corrosion-resistant and anti-irradiation, so adopt carbon fiber to have broad application prospects as the composite material of reinforcement, both can be used as the structural material bearing load, and can be used as again functional material and play a role.But up to the present on market, there is not yet the glass fiber reinforced plastic sand-inclusion pipeline that has than high wear resistance.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of preparation method of high abrasion glass steel clamp sand pipeline.
In order to achieve the above object, the preparation method of high abrasion glass steel clamp sand pipeline provided by the invention comprises the following step that carries out in order:
1) will with the weight ratio shuffling of 2-25: 75-98, become surperficial felt through the carbon fiber of oxidation processes and glass fibre, then surperficial felt is immersed in the silane coupler solution of 1-10% concentration and carries out surface treatment, time 0.5-1.5h, constantly the effects on surface felt stirs in this process, then takes out and repeatedly rinses well with deionized water;
2) by the dry 1.5-3.5h under the vacuum pressure of the temperature of 100-180 ℃ and 5-120kPa of the surperficial felt after above-mentioned cleaning, obtain dry surperficial felt;
3) above-mentioned dried surperficial felt is soaked to upper unsaturated polyester resin, then adopt the fixed length winding process to be wrapped in the surperficial and curing of pipe mould and make inside liner;
4) the glass fibre gauze belt that surface is covered with to the damp sand bar of being made by silica sand and unsaturated polyester resin is wrapped in the surface of above-mentioned inside liner and solidifies and make construction layer;
5) on the surface of said structure layer, adopt external chiasma hoop mode be wound around the glass fiber bundle that is soaked with unsaturated polyester resin and solidify and make external protection, finally repair, the demoulding, cleaning check namely can be made into described high abrasion glass steel clamp sand pipeline.
The model of described silane coupler is KH550.
The preparation method of high abrasion glass steel clamp sand pipeline provided by the invention adopts carbon fiber and glass fibre shuffling surface felt to prepare inside liner, utilize the characteristics of carbon fibre material itself to improve wear resistance, corrosion resistance, ageing resistance and the specific strength of inside liner, and can adjust the mechanical property of inside liner by the method that changes carbon fiber, glass fibre ratio, thereby improved the comprehensive mechanical property of pipeline, therefore can extend the working life of pipeline, in oil field, machinery, chemical industry and boats and ships etc. need the field of high-wear resistance to have broad application prospects.In addition, because the present invention only adds a small amount of carbon fiber in inside liner, so can not increase substantially the cost of pipeline.In addition, this preparation method process is simple, and without the existing equipment of large-scale redevelopment.
