Described inside liner, enhancement layer, external protection coating are bonded as one.
Described external protection coating is the external protection coating that polyurethane resin or vinyl ester resin, phenolic resin are made.
The preparation method of described environmental protection glass-reinforced plastic pipe comprises following operation: frp lining layer preparation section, bamboo chip pretreatment process, winding working procedure, external protection coating operation,
Described bamboo chip pretreatment process:
Mao bamboon is split into length: 2-6 meters, wide: the bamboo chip of 5-15mm, thick: 0.5-1.5mm, weight concentration 5-20%NaOH solution soaks after 10-60 minutes for 30-80 ℃, being dried to the moisture content weight content is 5-20%, with the continuously long bamboo chip of bonding one-tenth before and after the every bamboo chip, and be rolled into the bamboo chip volume, use on Stetch Wrapping Machine with convenient.
The weight content of moisture content surpasses 20% in the bamboo chip, can cause the bonding bad of bamboo chip, crosses to hang down then to cause bamboo chip easily broken.
Described winding working procedure:
Continuous rolling bamboo chip after debatching on the Stetch Wrapping Machine, is coated resin during by resin storage tank, be wrapped in to marshalling the liner outside of straight tube mould, reach design thickness through after the multi-lay winding.The pipeline that winds forms the enhancement layer of pipeline after solidifying.
Described resin is urea formaldehyde resin or epoxy resin, unsaturated polyester resin, polyurethane resin, and solidifying temperature is 20-100 ℃.
Described frp lining layer preparation section:
On the straight tube mould, make liner, form the inside liner of antiseepage, anticorrosion and inner wall smooth with anti-corrosion resin and glass felt;
Described external protection coating operation: the appearance at pipeline is coated with the anticorrosion water-fast resin of last layer as external protection coating.
Described anticorrosion water-fast resin is polyurethane resin or vinyl ester resin, phenolic resin.
Technological scheme of the present invention and Glass Steel Tube and RPMP difference be bamboo chip through the employing rolling of chemical treatment as reinforcing material, and non-glass fiber or carbon fiber etc.; Bamboo chip is carried out chemical treatment, can improve toughness, reduce fragility; Adopt thermosetting resin as tackiness agent, can make between bamboo chip and the bamboo chip bonding goodly, give full play to its intensity.In the structure of this programme pipeline is formed,, give advantages such as body light weight, high strength, high rigidity, high tenacity owing in the enhancement layer of body, adopted bamboo as reinforcing material; On liner, adopted and structure and material common in Glass Steel Tube, therefore also inherited the good characteristics such as anticorrosion, inner wall smooth of Glass Steel Tube; On external protection coating,, guaranteed that body has good durable weatherability owing to applying one deck employing polyurethane resin or vinyl ester resin, the anticorrosion water-fast material of phenolic resin.
The present invention compares with PVC, polypropylene pipe, has higher intensity, rigidity, can save petroleum resources, to compare matter lighter, with low cost with Glass Steel Tube and glass reinforced plastic sand pipe, the manufacturing efficiency height, have similar strength and stiffness, reinforcing material is the renewable resources of environmental protection, low energy consumption, can adopt the binder of non-petroleum product, can save petroleum resources, and for the development and use of agricultural resource, increasing farmers' income has positive effect.
