Problems solved by technology

However, photoradiation-induced polymerization can only produce very thin samples due to the limitation of light penetration ability, and it is difficult to manufacture thicker materials, so the application is limited.

Embodiment 1

[0034]Dissolve 20 parts of heavy polymethyl methacrylate (organic glass) in 80 parts of heavy methyl methacrylate monomer under heating, add 1 part of heavy azobisisobutylcyanide (AIBN), dissolve as Dipping solution. Immerse the low-alkali untwisted glass fiber in 10% ethyltrimethoxysilane acetone solution, then dry it, impregnate it through the impregnation chamber, enter the mold under the traction of the tractor, and adjust the power of the microwave heater to 500W , to obtain rod-shaped continuous fiber-reinforced polymethyl methacrylate with a diameter of 2 mm.

Embodiment 2

[0036] Dissolve 25 parts by weight of high impact styrene (HIPS) in 75 parts by weight of methyl methacrylate and isooctyl methacrylate mixed monomer under heating, add 5 parts by weight of dipropylene terephthalate The ester is dissolved, and then 1.5% by weight of the monomer tert-butyl peroxyisooctanoate (TBPO) is added to dissolve as an impregnating solution. Immerse the low-alkali untwisted glass fiber in 10% vinyltrimethoxysilane (A-151) acetone solution, then dry it, impregnate it through the impregnation chamber, enter the mold under the traction of the tractor, and adjust the microwave heating The power of the device was 500W, and a rod-shaped continuous fiber-reinforced cross-linked high-impact composite material with a diameter of 2mm was obtained.

Embodiment 3

[0038] 100 parts by weight of propylene glycol diacrylate is dissolved with 1 part by weight of azobisisobutylcyanide (AIBN) as an impregnation solution, and the glass fiber treated with silane coupling agent-methacryloxypropyltrimethoxysilane on the surface is impregnated , Through the pultrusion machine, under the microwave heater 600W, the glass fiber reinforced thermosetting composite material is obtained.

Abstract

A continuous long fibre-reinforced reactive resin product is made up from the monomer able to be polymerized by free radicals through immersing long fibres, pre-shaping by a mould, microwave reactive cavity for polymerizing and curing, moulding, cooling and solidifying. Its advantages are high polymerizing speed, and high adhesion between fibres and resin.

Description

technical field [0001] The invention relates to a manufacturing method of resin, in particular to a manufacturing method of continuous long fiber reinforced reactive resin. Background technique [0002] The most common way to manufacture fiber-reinforced thermoplastic resin is to melt the resin and extrude the fiber through a screw extruder. Due to the shearing action of the screw, the fiber is cut off and becomes very short (about 0.3-0.5mm), which limits the performance of the fiber as a reinforcing material. In addition, screw extrusion requires high temperature, and the melt viscosity is very high, which makes it difficult for the resin to infiltrate the fiber, and it is difficult to obtain a composite material with good resin-fiber bonding. Secondly, it is difficult to carry out surface treatment on the surface of each fiber to improve the interfacial bonding between resin and fiber to improve the performance of composite materials. [0003] The thermoplastic resin is...
