Abstract

The invention discloses a preparation method of epoxy resin zirconium tungstate concrete. The epoxy resin zirconium tungstate concrete comprises a component A, a component B and a compound C, wherein the component A comprises the following components in percentage by weight: 70-80% of epoxy resin, 10%-15% of curing agent and 10%-20% of diluent; the component B is zirconium tungstate, the quality mass purity of which is no less than 97%; the component C is aggregated rocks; the weight ratio of the component A to the component B is 1: 2. 2 to 1: 3.5; and the weight ratio of the mixed component A and component B to the aggregated rocks is 1: 1.17 to 1: 1.61. Compared with a conventional concrete technology, the preparation method of the epoxy resin zirconium tungstate concrete has the advantages that the thermal expansion coefficient of the epoxy resin zirconium tungstate concrete is obviously reduced by introducing the zirconium tungstate which is a negative thermal expansion coefficient material to the expoxy resin concrete material, and meanwhile, the strength of the material is enhanced, thus the shortcoming that the resin concrete product is easy to deform at high high-temperature and high high-humidity environments is further solved.

Description

technical field [0001] The invention relates to the technical field of concrete manufacture, and is particularly suitable for an epoxy resin zirconium tungstate concrete material and a preparation method for the base of an ultra-high-precision machining center. Background technique [0002] With the rapid development of modern manufacturing industry, precision and ultra-precision machining are more and more widely used, and the quality and level of precision machinery have become an important factor to measure the strength and weakness of countries in the world today in the competition of science and technology and even armaments. standard. This especially requires ultra-precision machining machine tools to have extremely high precision, dynamic and static stability and thermal stability. According to statistics, 80% of the deformation of the machine tool during processing comes from thermal deformation, and the higher the processing accuracy requirements, the greater the n...
