[0026] A manufacturing process of ultraviolet light curing pipeline material, comprising the following steps:
[0027] (1), dry material laying: using a laying and folding machine to lay out and laminate in the order of inner film 1, glass fiber 2, outer film 3, and non-woven fabric 31 from bottom to top to form dry material semi-finished products; the inner film and outer film The film is made of transparent adhesive material with single-sided adhesive and double-sided adhesive respectively;
[0028] (2), impregnation liquid ingredients: resin, thickener, diluent, ultraviolet photoinitiator are compounded into impregnation liquid in mixing container, standby; Said diluent is reactive diluent with respect to described resin;
[0029] (3) Impregnation: In a closed container, use a vacuum pump to pump to a relative vacuum higher than -30mbar; fill the impregnating liquid into the gap between the layers of the semi-finished dry material, so that the impregnating liquid and the se...

Abstract
The invention discloses a manufacturing process of ultraviolet light-cured pipeline materials, which includes the steps of laying out dry materials, mixing ingredients for impregnating liquid, impregnating, and folding and packaging; wherein laying out dry materials: laminating inner film, glass fiber, outer film, and non-woven fabric in sequence ; Impregnation liquid ingredients: mixed resin, thickener, thinner, ultraviolet photoinitiator; Impregnation: Vacuum pump suction, impregnation liquid is filled into the gap between layers of dry material semi-finished products, so that it is fully infiltrated, and rolled, repeated operations, airing Dry and save. The product of the present invention can be used in the temperature range of -50-200°C for a long time, and the expected service life can reach about 70 years, and it has excellent wear resistance, impact resistance, corrosion resistance, light weight, convenient construction and curing. It has the characteristics of reliability, short construction period and convenient maintenance in the later stage, and has wide application prospects and great commercial value.
Description
technical field [0001] The invention belongs to the technical field of non-excavation pipeline repair, and in particular relates to a manufacturing process of ultraviolet curing pipeline material. Background technique [0002] Nowadays, the laying of underground pipe network is also extending to various places. Due to the impact of wear, aging, corrosion, etc. during transportation and use, the pipeline needs to be repaired or replaced. Traditional underground pipeline repair needs to excavate the ground first, then repair and replace the pipeline construction, and finally fill the road surface. Such excavation construction method is inefficient and causes a lot of inconvenience to road traffic. [0003] Trenchless pipeline repair technology emerged in developed countries in the 1970s, and has gradually been used more and more widely in my country in recent years; this technology is not only efficient, but also has a negative impact on the surrounding traffic, environment,...
