Abstract
The invention discloses a high temperature resistant modified nylon composite material, which is prepared by granulation on the following raw materials by weight: 65-67 parts of modified nylon PA6, and 55-57 parts of PA66+15% GF. The material provided by the invention has good high temperature resistance and high strength.
Description
Technical field
The present invention relates to nylon material field, is exactly a kind of heat resist modification nylon combination material.
Background technology
Because nylon has a lot of characteristics, therefore, at aspects such as automobile, electric installation, Machinery Ministry structure, transportation equipment, weaving, papermaking equipments, be used widely.
Along with the miniaturization of automobile, the light-weighted process of the high performance of electronic electric equipment, mechanical means accelerate, to the demand of nylon Gao Geng great more.Particularly nylon, as structural material, has proposed very high requirement to aspects such as its intensity, thermotolerance, winter hardiness.The inherent defect of nylon is also the important factor that limits its application, particularly for PA6, the large kind of PA66 two, with the kind such as PA46, PAl2 than thering is very strong price advantage, though some performance can not meet the requirement of relevant industries development.Therefore, must by modification, improve its some performance for a certain Application Areas, expand its Application Areas.Due to the strong polarity of PA, water absorbability is strong, poor dimensional stability, but can improve by modification.
Summary of the invention
In order to alleviate shortcomings and deficiencies of the prior art, the object of the present invention is to provide a kind of heat resist modification nylon combination material that intensity is high.
Above-mentioned purpose realizes by following scheme:
A heat resist modification nylon combination material, is characterized in that, it is that raw material granulation by following weight parts makes:
Modification of nylon PA6 65-67, PA66+15%GF 55-57;
Described modification of nylon PA6 is made by the raw material granulation of following weight parts: nylon PA6 65-68, PBT 8-10, polycaprolactone 3-5, ethylene bis stearamide 1-2, silicone oil 0.1-0.2, silane coupling agent KH570 0.5-1, irgasfos 168 1-2, Zinic stearas 1.5-2, modified montmorillonoid 5-10;
The preparation method of described modified montmorillonoid is:
The sodium hydroxide solution that is 10-15% by concentration by polynite soaks 3-4 hour, more extremely neutral with deionized water wash, after oven dry, adds the Silane coupling agent KH550 that is equivalent to powder weight 2-4% to stir, and dries, and is ground into powder, obtains.
Described a kind of heat resist modification nylon combination material, is characterized in that, manufacture method is:
(1) get and prepare modification of nylon PA6 desired raw material and be placed in high-speed mixer and mixing 3-6min according to weight part, the mixture obtaining adds in twin screw extruder through main spout, controlled working temperature is at 250-260 ℃, screw rod revolution is at 380-500rpm, and after melting, extruding pelletization obtains modification of nylon PA6;
(2) according to weight part, modification of nylon PA6 and nylon PA66 are placed in to high-speed mixer and mixing 3-6min, the mixture obtaining adds in twin screw extruder through main spout, controlled working temperature is at 260-270 ℃, and screw speed is at 500-600rpm, and after melting, extruding pelletization obtains product.
Described nylon PA66+15%GF refers to the nylon PA66 that 15%GF glass fibre strengthens.
Beneficial effect of the present invention is:
The invention solves the general resistance to elevated temperatures of existing nylon material poor, the low performance deficiency that waits of intensity, compound with all the other raw materials, products obtained therefrom steady quality, has improved production efficiency, has reduced production cost.
