Abstract

The invention discloses a corrosion-resisting and ageing-resisting cement brick and a preparation method thereof and relates to the technical field of building materials. The cement brick is preparedfrom the following raw materials in parts by weight: 30 to 40 parts of cement, 10 to 18 parts of perlite, 12 to 22 parts of dickite, 18 to 24 parts of galapectite, 15 to 25 parts of a modified pure acrylic emulsion, 8 to 14 parts of graphene, 4 to 10 parts of aluminum oxide, 2 to 8 parts of antimonous oxide, 6 to 12 parts of sodium dodecylbenzene sulfonate, 2 to 5 parts of a thickener and 1 to 5 parts of an additive. The preparation method of the cement brick comprises the steps of treating the perlite, the dickite and the galapectite; mixing and stirring; pouring a mold and carrying out pressed molding; curing. The cement brick has good corrosion resistance and ageing resistance and has an excellent mechanical property, and can meet ever-changing social requirements.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a corrosion-resistant and aging-resistant cement brick and a preparation method thereof. Background technique [0002] Cement bricks are mainly suitable for exterior walls and pavements. With the rapid development of the construction industry and the continuous improvement of people's living standards, cement bricks with better performance are required. The existing cement bricks mainly have low strength, poor corrosion resistance and The disadvantage of poor anti-aging performance has been unable to meet the changing needs. [0003] The Chinese invention patent application with the publication number CN107129257A discloses a wear-resistant and anti-aging insulation brick and its preparation method. Vanadium extraction tailings 13-22, magnesium oxychloride cement-40-50, sugar factory filter mud 12-19, sulfuric acid slag 15-20, fluorine gypsum 11-18, pebble...
