Abstract

The invention provides a preparation method of a glass / metal composite material. The preparation method comprises steps as follows: uniformly mixing 50 to 56% of SiO2, 11 to 14% of Al2O3, 15 to 22% of CaO, 0 to 5% of MgO, 0 to 10% of B2O3, 0.1 to 2% of Na2O, and 0.1 to 1% of Sb2O35 in mass percentage, so as to form mixture; and melting and quenching by water to obtain glass powder; and forming and roasting 45 to 55% of the glass powder and 55 to 45% of copper powder in mass percentage, thus obtaining the glass / metal composite material. By adopting the preparation method, shortcomings of a conventional preparation method that a technology is complex, preparation time is long, glass content is low, and a temperature for using the material is low can be avoided. The glass / metal copper composite material prepared by the preparation method provided by the invention is high in strength, and a usage temperature is over 600 DEG C, acid resistance and alkali resistance are excellent, raw materials are low in cost and rich in source, a preparation technology is simple, and industrial production can be achieved. The prepared glass / metal copper composite material can be used as a high-quality material for replacing a copper metal and a high-quality wearproof and high-temperature resistant composite material.

Description

technical field [0001] The invention relates to a preparation method of a composite material, in particular to a preparation method of a glass / metal copper composite material. Background technique [0002] At present, the parts with relative sliding motion, such as bushings, bearing bushes, navigation, and skateboards used in various mechanical transmissions, use corresponding anti-friction and wear-resistant materials under different working conditions, and copper-based wear-resistant alloys are commonly used , Babbitt alloy, etc. There are also many reports of self-lubricating and anti-friction materials in relevant literature at home and abroad. For example, in 1984, powder metallurgy (Powder metallurgy vol 1, No1: 30-38) reported "production of metallic glass composite materials by powder metallurgy"; this method uses powder Metallurgical preparation of metallic glass composite materials is complex and inefficient. In 1987, The International Journal of Powder metallurg...
