Embodiment 1

[0012] Embodiment 1, providing a glass fiber-reinforced high-temperature nylon raw material that does not expose fibers, which is composed of the following components by weight ratio, high-temperature nylon: 65%, alkali-free glass fiber: 30%; heat stabilizer: 0.8%, glass fiber treatment Agent: 1.0%, dye toner: 0.7%, other additives: 2.5%;

[0013] First bake the high-temperature nylon particles at 100 degrees for 3-4 hours, then mix them with the glass fiber treatment agent in proportion, and place them at a constant temperature of 50 degrees for 12 hours, and then mix them with heat stabilizers, dyes, toners and others in time. The additives are weighed according to the proportion and mixed in the mixer at low speed for 10 minutes. The mixer adopts low-speed mixing and is made of stainless steel. The gap between the stirring blade and the cylinder wall should be less than 0.5 cm. The mixing effect of raw and auxiliary materials should be visually inspected for various particle...

Abstract

The invention relates to an organic high-molecular composite material, in particular to a glassfiber reinforced high-temperature nylon without fiber exposion and a preparation method thereof. The high molecular composite material comprises the following components in parts by weight: 45.5%-95% of high-temperature nylon, 5%-55% of alkali-free glass fibers, 0.1%-3.0% of heat stabilizers, 0.1%-3.0% of glass fiber finishing agents and 1.3%-5.5% of other auxiliary agents. The glassfiber reinforced high-temperature nylon without fiber exposion and the manufacturing process thereof have excellent long-term and short-term thermal properties, high temperature resistance, excellent mechanical strength, same strength and toughness under a damp environment, outstanding chemical resistance, dimension stability, excellent electrical characteristics and good appearance.

Description

technical field [0001] The invention relates to an organic polymer composite material, more specifically, relates to a fiberglass-reinforced high-temperature nylon raw material without exposed fibers. The present invention also relates to the method for making this high temperature nylon raw material Background technique [0002] At present, the international use of plastics to replace metals in industry continues to expand, and the development of enhanced high-temperature nylon makes this speed and scope more extensive. High temperature nylon can bring higher temperature performance to many components. This material can withstand a continuous high temperature of 180 ° C, and can also maintain good dimensional stability. Has excellent long-term and short-term thermal performance, can withstand the high temperatures generated by infrared (IR) reflow ovens used in lead-free soldering processes, has excellent mechanical strength, and provides the same strength and toughness i...
