preparation example Construction

[0048] Its preparation method comprises the following steps:

[0049] 1) Mix the ingredients evenly according to the weight ratio;

[0050] 2) Mix the mixture in step 1) under heat and pressure. Temperature 280°C-300°C, pressure 30-40MPa;

[0051] 3) Heat and pressurize the kneaded material obtained in step 2) to wire drawing. Temperature 280°C-300°C, pressure 25-30MPa;

[0052] 4) Divide and granulate.

[0053] The combination of components of the nylon composite reinforcing material of the present invention is based on the principle of step gradation: when materials of each diameter or particle size are arranged, there will be triangular gaps; the purpose of step matching is to fill up these gaps step by step, so as to enrich the steps. Reduce creep and increase strength. The selection of the diameter / particle size of the step-graded substance requires that the diameter of the next-level substance is exactly the circle cut gap of the previous-level substance diameter. ...

Abstract

A disclosed nylon composite enhanced material utilizes a gradient grading filling principle, and comprises the following compositions: nylon 11, basalt fiber possessing the diameter of 13 mum and accounting for 20-40% by weight of nylon 11, glass fiber possessing the diameter of 6 mu m and accounting for 20-40% by weight of basalt fiber, glass fiber possessing the diameter of 2 mu m and accounting for 20-40% by weight of the glass fiber with the diameter of 6 mu m, a sub-nanometer material possessing the particle size of 400-600 nm and accounting for 20-40% by weight of the glass fiber with the diameter of 2 mu m, and a nanometer material accounting for 20-40% by weight of the sub-nanometer material. The nylon composite enhanced material is novel in combination and scientific in material selection and grading, the mesoscopic mechanics structure is gradually filled, a normal-temperature metal substitute structural material is developed and is sustainable, regenerable, free of pollution, low in energy consumption, highly resistant to corrosion and excellent in performances, and is capable of replacing a conventional normal-temperature steel material or metal.

Description

technical field [0001] The invention belongs to the field of new materials, and in particular relates to a nylon composite reinforcing material and a preparation method thereof. The nylon composite reinforcing material is a kind of step-gradation filled void-filled reinforced nylon, which can replace steel and metal at normal temperature. Background technique [0002] The traditional commonly used metal materials such as normal temperature steel come from ore and need to be smelted at high temperature. The resources are increasingly depleted and imported in large quantities. They are not renewable and face the bottleneck of sustainable development. High energy consumption, high carbon emissions, and high pollution production methods are deteriorating the ecology and living environment. For example, the smog continues to increase, which is posing a survival crisis for the Chinese people and seriously endangering the health, life, and quality of life of the Chinese people. Mor...
