Abstract

The invention discloses a cement-base molding material and a preparation method thereof. The cement-base molding material comprises the following components in percentage by weight: 15-25% of white cement, 2-7% of metakaolin, 50-70% of quartz sand, 8-15% of heavy calcium carbonate, 3-8% of rubber powder, 0.1-0.5% of cellulose ether, 0.1-0.5% of water repellent, 0-3% of inorganic pigment, 0.1-0.5% of defoaming agent, 0.2-0.6% of nano titanium dioxide, 0.2-0.6% of diatomite and 0.1-0.5% of bentonite. The nano titanium dioxide is carried on the diatomite. The cement-base molding material has the advantages of high plasticity, favorable water resistance, favorable weather resistance and adjustable color, is suitable for manufacturing molded stone rockwork, subject facades and other artificial landscapes, and can implement the realistic effect of the artificial landscapes. When being used for molding the surface layer of the artificial landscape, the cement-base molding material has better self-cleaning and purification effects. The combination of the bentonite and cellulose ether enhances the water retention property and improves the constructability of the mortar, so that the mortar becomes smooth without sticking to the knife, and is convenient for construction.

Description

technical field [0001] The invention belongs to the field of materials, and more specifically relates to a cement-based plastic material and a preparation method thereof. Background technique [0002] Cement-based plastic material is a theme packaging material for artificial landscapes, suitable for the construction of plastic rockery and theme facades. Sculptors use this material, combine it with sculpture technology, learn from sculpture production methods, and develop a plastic stone rockery and themed facade landscape with a high degree of simulation and good durability. Different from ordinary cement mortar mixed with cement sand on site, plastic mortar introduces a large number of new materials to modify and is a special ready-mixed dry powder mortar produced in a factory. Factory production can guarantee the reliability of product quality, and the modification of new materials greatly improves the construction, sculpture and durability of mortar. [0003] At present...
