Embodiment 1

[0017] Embodiment 1, adopt the epoxy resin of high molecular weight, medium molecular weight and low molecular weight according to product requirement, add the promotor of conventional consumption, curing agent and coupling agent uniformly mix by conventional process, epoxy resin is 99.6% by weight percentage, Accelerators, curing agents and coupling agents are commonly used in epoxy resins to make solvent-free high-viscosity epoxy resins, which are evenly coated on the surface of release paper on an epoxy resin coating machine to obtain solvent-free rings. epoxy resin film, then cooled, coiled and stored; then the single continuous glass fiber and fabric glass fiber are sorted, and on the prepreg equipment, the solvent-free epoxy resin film with release paper is laminated by heating rollers On both sides of the single glass fiber and the fabric glass fiber, a composite material is formed in which the upper covering epoxy resin layer, the fabric glass fiber, the single glass fi...

Embodiment 2

[0019] Embodiment 2, adopt the bisphenol A epoxy resin of high molecular weight, middle molecular weight and low molecular weight of 99.3% by weight according to product requirements, add 0.2% two N, N-dimethylureidotoluene accelerator, 0.5% dicyandiamide curing agent and conventional dosage of KH-550 silane coupling agent are evenly mixed to make solvent-free high-viscosity epoxy resin. KH-550 silane coupling agent is produced by Gaizhou Hengda Chemical Co., Ltd.; Epoxy resin coating machine is evenly coated on the surface of the release paper to prepare a solvent-free epoxy resin film, then cooled, coiled and stored; then the single continuous glass fiber and fabric glass fiber are sorted, and the On the prepreg equipment, the solvent-free epoxy resin film with release paper is laminated and pressed on both sides of the single glass fiber and the fabric glass fiber through a heating roller to form an upper covering epoxy resin layer, fabric glass fiber, and single glass fiber...

Abstract

The invention discloses single fabric glass fiber composite material and a preparing method thereof. The invention is characterized in that the invention comprises an upper covering epoxy resin layer (1), fabric glass fiber (2) which is arranged at under the upper covering epoxy resin layer (1), single glass fiber (3) which is arranged under the fabric glass fiber (2), and a lower covering epoxy resin layer (4) which is arranged under the single glass fiber (3), wherein a solvent-free epoxy resin adhesive film is adopted by the upper covering epoxy resin layer (1) and the lower covering epoxy resin layer (4); and the method of preparation has the following twp steps: firstly, the solvent-free epoxy resin adhesive film is prepared, and then the solvent-free epoxy resin adhesive film is compounded and pressed on the two surfaces of the single glass fiber and the fabric glass fiber. With the advantages that the volatile content is low, the material is pollution free, the longitudinal and transversal strength is high, and the tenacity is good, and the method of preparation is simple and labor-saving, the single fabric glass fiber composite material can be widely applied to the production of fishing tackles and sporting goods.

Description

Technical field: [0001] The invention relates to the technical field of glass fiber composite materials, in particular to a single-item, fabric glass fiber composite material and a preparation method thereof, which are mainly used in the production of fishing tackle and sporting goods. Background technique: [0002] At present, the existing glass fiber materials even use the weaving technology of the textile industry to weave the fibers vertically and horizontally, and then use the wet infiltration technology to make glass fiber materials. The glass fiber materials made in this way have the following disadvantages. 1. Due to the use of There is a solvent in the wet impregnation material, which destroys the performance of the resin; 2. There are bubbles in the fiber weaving, which affects the quality of the material; 3. The radial strength of the material is insufficient, and the weight per unit length is heavy, which wastes the fiber; 4. Volatile content High, affecting prod...
