Abstract

The invention provides a 3D printing quartz sand composite material. The composite material contains the following components in parts by weight: 80-100 parts of quartz sand powder, 5-15 parts of polyisocyanate, 5-15 parts of epoxy resin, 5-8 parts of stearamide and 1-5 parts of oleamide, wherein the particle size of the quartz sand powder is less than 200 meshes. By utilizing the quartz sand as the main production raw material, the cost is relatively low; and the mainly chemical component of the quartz sand is silicon dioxide, so that the alkalinity of the product can be reduced, the additionamount of a curing agent is reduced, the printing cost is lowered, and the layering of a powdery material in the printing process is effectively avoided; and the 3D printing quartz sand composite material is added into 3D printing equipment and is paved with sand and printed, and a printing test block is taken out, and a detection result shows that a printed solid is high in compressive strengthand good in performance.

Description

technical field [0001] The invention relates to the field of quartz sand, in particular to a 3D printed quartz sand composite material. Background technique [0002] Quartz sand is a kind of non-metallic mineral, which is a kind of hard, wear-resistant and chemically stable silicate mineral, and its main chemical composition is silicon dioxide. The color of quartz sand is milky white or colorless and translucent, the hardness is 7.6, brittle without cleavage, shell-like fracture, grease luster, relative density 2.67, its chemical, thermal and mechanical properties have obvious anisotropy, insoluble in acid , slightly soluble in potassium hydroxide solution, with a melting point of 1750°C. [0003] Quartz sand is one of the very important non-metallic mineral raw materials. It is not a chemical dangerous product. Its unique physical and chemical properties make it widely used in glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, meta...
