Abstract
The invention relates to a calcium sulfate crystal whisker glass fiber composite reinforcing nylon material and a preparation method thereof. The material is prepared by the following raw materials in weight percent: 50-70% of nylon 6, 5-20% of calcium sulfate crystal whisker, 5-30% of alkali-free glass fiber, 0.2-5% of silane coupling agent, 0.1-0.5% of antioxidant, and 0.1-0.5% of lubricant. The preparation method comprises the following steps: weighing raw materials according to the above weight percent; placing the calcium sulfate crystal whisker and the silane coupling agent into a high mixing machine to process for 2-5min; discharging; and placing the evenly-mixed raw materials into a screw machine for extrusion and pelletizing. The invention is characterized in that the prepared nylon material has higher mobility and higher strength, can improve surface floating fiber and can be used for manufacturing surface materials with higher surface requirements such as cars, electronics and the like.
Description
Technical field
The present invention relates to a kind of calcium sulfate crystal whisker glass fiber composite reinforcing nylon material, this material has higher intensity, and mobile, and glass leaks outside and all improves significantly.Can make and have production unit, the instrument that high strength requires, instrument, meter case etc.
Background technology
Nylon is extensively applied to every profession and trade with its excellent comprehensive performances, glass fibre and mineral-filled modification of nylon have superperformances such as high strength, high heat-resisting, highly anti-fatigue, low mould shrinkage, therefore are widely used in fields such as automobile, machinery, household electrical appliances, aviation and military parts.
Modified nylon material in the market mainly is glass and mineral-filled modified composite material.Though the filling-modified nylon of glass fibre has excellent mechanical property and low shrinking percentage, product appearance is coarse, even phenomenons such as glass lines and floating fibre can occur; Although mineral-filled nylon is better than the former in appearance, the intensity and the toughness of material are on the low side, and shrinking percentage is also bigger than normal relatively.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of calcium sulfate crystal whisker glass fiber composite reinforcing nylon material and preparation method thereof for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions: a kind of calcium sulfate crystal whisker glass fiber composite reinforcing nylon material, it is characterized in that, and make by following materials of weight proportions:
