Problems solved by technology

[0004] The inventors of the present application found in the research that the disadvantage of adopting the negative pressure impregnation method is that the negative pressure will cause the small molecule mixtures such as curing agent and crosslinking agent in the liquid resin to be drawn out by the vacuum pump, which will affect the effect of the active ingredients, and simultaneously small Molecular materials will be released into the atmosphere to pollute the environment and increase environmental pressure

[0043] Example 1: Production of a 300mm diameter round pipe

[0044] 1. Resin storage tank and infiltration tank: the resin storage tank is a 50-liter spherical tank, which consists of two upper and lower petals, which are connected by flanges; two sets of infiltration tanks, long cylinders with a size of φ500mm*1000mm, and rubber seals The size of the sealing ring is φ285mm in diameter, the pressure plate is made of polytetrafluoroethylene plate, and an ultrasonic generator, solenoid valve, and float valve are installed on the cylinder. figure 1 Connect the assembly.

[0045] 2. Infiltration and curing of glue: put the resin that has been prepared with curing agent, crosslinking agent, filler and other additives into the kettle, and raise the temperature to 70°C, and pre-arrange the mandrel on the mandrel by weaving The fibers form a fiber fabric, and the fiber fabric moves forward into the dipping tank; the positive pressure source is activated, and the pressure passes thro...

Abstract

The invention provides a fiber fabric soaking device. The fiber fabric soaking device comprises a storage kettle (2), glue soaking tanks (9, 20) and a mould core (19), the storage kettle (2) stores glue soaking materials and communicates with the glue soaking tanks (9, 20), the glue soaking tanks (9, 20) are provided with ring plates (11), each ring plate is provided with a ring plate groove, eachring plate groove is internally provided with a rubber ring (21) matched with the corresponding ring plate groove, the mould core (19) penetrates through the rubber rings (21) and runs through the glue soaking tanks (9, 20), and fiber fabric (10) is pulled to move from the surface of the mould core (19) to be subjected to continuous positive pressure glue soaking.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a fiber fabric soaking device and method. Background technique [0002] In the production of fiber-reinforced resin-based composite materials, especially in the pultrusion process, the pre-arranged continuous fiber fabric is infiltrated. Usually, the fibers are fully impregnated by industrial technology methods, and the high-quality fiber is obtained through mold curing. performance products. In the process of fiber pre-arrangement and dipping and curing, the scraping between fibers and fibers, fibers and dipping systems, fibers and molds should be reduced as much as possible for the arranged fibers to ensure the integrity of the fibers so as to maximize to obtain the strength of the composite material. The methods of fiber pre-arrangement include: weaving, winding, puncturing, hooking, etc. to arrange a single bundle of fibers into a fiber fabric of a certain shape. ...
