Vacuum filling and mixed soaking device for manufacturing resin composite material and using method thereof

Abstract

The invention provides a vacuum filling and mixed soaking device for manufacturing a resin composite material. The vacuum filling and mixed soaking device comprises a vacuum pre-filling bag and fibers filled in the vacuum pre-filling bag, wherein a vacuum exhaust pipe is arranged at the upper end of the vacuum pre-filling bag, and the end, located in the vacuum pre-filling bag, of the vacuum exhaust pipe is connected with a winding flow guide pipe in a communicating mode; the winding flow guide pipe is annularly arranged in the vacuum pre-filling bag, and a resin filling and exhausting three-way pipe is arranged at the bottom of the vacuum pre-filling bag; the resin filling and exhausting three-way pipe is composed of a resin filling end, an exhausting end and a guide pipe; and the guide pipe is located in the vacuum pre-filling bag and is in lap joint with the winding flow guide pipe. According to the invention, the fiber material is subjected to negative-pressure vacuum pumping in advance to exhaust most air, then the resin material is filled, and the air is continuously pumped and exhausted in the filling process, so that the problems that the content of bubbles is too large and the bubbles are not easy to eliminate in the mixed impregnation process are basically solved, the mixed impregnation quality of the fiber resin material is ensured, and thus, the reinforcing engineering quality is further ensured.

Description

technical field [0001] The invention relates to a resin mixed impregnation device, in particular to a vacuum pouring mixed impregnation device for making resin composite materials and a use method thereof. Background technique [0002] Resin refers to an organic substance whose relative molecular weight is uncertain but usually relatively high. It is solid, medium solid, pseudo-solid, and sometimes liquid at room temperature. In a broad sense, it refers to a polymer or prepolymer used as a plastic substrate. The resin has a softening or melting temperature range, and has a tendency to flow under the action of an external force. It often takes the shape of a shell when broken, and is generally insoluble in water, but soluble in organic solvents. [0003] Fiber resin composite materials have the characteristics of high strength, fast solidification, environmental protection and non-toxicity, etc., and are widely used in field geotechnical engineering reinforcement construction...

AI Technical Summary

Problems solved by technology

At present, in the field construction process, the method of directly mixing fibers and resins is often used for production. During the production process, a large number of small micro-bubbles will be generated, accounting for about 5% to 10% of the total volume of the composite material. The existence of these bubbles will lead to solidification. The strength of the fiber resin material decreases and the durability deteriorates

Due to the characteristics of the impregnation material, it is currently impossible to eliminate these small micro-bubbles by standing still and negative pressure vacuum, and standing for too long will cause the resin to start to solidify when it is not used, making the reinforcement effect worse or impossible. use
