Abstract

The invention discloses high-performance building cement and a preparation method thereof, wherein the high-performance building cement is prepared from the following raw materials by weight: 20.4-33.6 parts of sulphoaluminate clinker, 3-5 parts of a bamboo phenol alcohol liquefaction resin, 3-8 parts of an AS resin, 0.5-1.5 parts of carboxymethyl cellulose, 23-47 parts of a core-shell acrylic elastic emulsion, 8-20 parts of waste paper pulp, 3-6 parts of a heat stabilizer, 0.9-4.9 parts of a chemical-resistant modifier, 15-20 parts of 4-hydroxy-3-methoxyphenylethyl alcohol, 10-25 parts of a heat conduction filler, 10-18 parts of slag micro-powder, 0.75-2.65 parts of infrared reflective titanium dioxide, 0.4-0.6 part of a light stabilizer, 0.1-0.8 part of a coupling agent, 0.7-4.3 parts of an accelerator, 4-8 parts of bamboo fiber, 2.5-8.5 parts of silicon nanoparticles, 7-13 parts of nanometer calcium carbonate, and the like. The high-performance building cement of the present invention has advantages of good durability, good weathering resistance, good thermal insulation, and good strength.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a high-performance building cement and a preparation method thereof. Background technique [0002] Cement is an indispensable building material in human life and social production. It is used in a wide range and in large quantities, and is known as "the grain of the construction industry". In recent years, with the vigorous development of the domestic construction industry, the requirements for the strength and durability of the cement consumed in the construction process have been continuously increased. At the same time, the existing cement has poor thermal insulation performance and weather resistance, which needs further development and improvement. Contents of the invention [0003] In order to solve the above problems, the present invention provides a high-performance building cement and a preparation method thereof, which have good durability, weather resistance, heat i...
