Problems solved by technology

However, due to the obvious fluidity of the resin, it has a more obvious impact on the operation and transportation of the product. How to use the low-viscosity grouting process and the conversion to high-viscosity is still an obvious challenge in this industry
[0004] At present, the process mainly uses fillers such as thixotropic agents to realize the phase transition of the resin, but the filler has many uncontrollable factors in the change of the properties of the overall material, such as uneven mixing, which also sets many obstacles to the improvement of the production process.

Abstract

The invention discloses a 4A type molecular sieve modified photocuring pipeline repair lining material and a processing technology. The photocuring pipeline repair lining material is formed by sequentially coating an anti-ultraviolet film, a resin isolation film, a vacuum import isolation film, a glass fiber axial braided fabric, a waterproof lining braided fabric and a high light transmittance film, and is prepared through impregnation in resin mother liquid. The product has reasonable design and novel process, wherein the molecular sieve is used as a core catalyst, so that based on the adsorption capacity and adsorption heat release capacity of the 4A type molecular sieve to small molecular organic substances, the curing rate is remarkably increased, the resin mother liquor is subjectedto photo-induced curing at the efficiency close to 100%, the curing efficiency is high, the effect is good, and the toughness of a finished product is high; in addition, the physical property is extremely good, and the repairing capability, the corrosion resistance and the decontamination capability are also realized.

Description

technical field [0001] The invention relates to the technical field of pipeline repair materials, in particular to a 4A-type molecular sieve-modified light-cured pipeline repair lining material and a processing technology. Background technique [0002] Ultraviolet curing non-excavation repair technology refers to the use of mechanical traction to drag the felt hose filled with photosensitive resin into the repaired pipeline, inject compressed air to make it close to the inner wall of the pipeline, and irradiate the resin in the pipeline through ultraviolet light. Internal curing to form a high-strength resin-lined new pipe lining repair technology for the whole section of the pipeline. [0003] The current technology is to combine various types of unsaturated polyester resins, polyurethane resins or epoxy acrylic resins with glass fiber axial braids, and under the action of ultraviolet light (including mercury lamps, LEDs, etc. light sources), the process is initiated by pho...
