Abstract
The invention discloses 3D printing mortar with high bonding strength. The 3D printing mortar comprises the following raw materials in parts by weight: 50-65 parts of ordinary portland cement, 60-80 parts of weathered coal, 15-24 parts of bentonite, 8-14 parts of mica powder, 10-16 parts of zeolite powder, 4-10 parts of flax fiber, 2-6 parts of calcium sulfate whisker, 4-8 parts of asphalt micro-powder, 1-3 parts of sodium carbonate, 0.5-1.5 parts of a water reducing agent, 0.8-1.6 parts of soft sugar, 0.1-0.8 part of an air entraining agent and 0.5-1.45 parts of sodium carboxymethyl cellulose. The 3D printing mortar provided by the invention not only has convenient material drawing and a low price and realizes reasonable utilization of resources, but also enables a product to have a function of keeping the plasticity of mortar, solves a bleeding problem easily caused by weathered coal and bentonite as raw materials, and ensures the fluidity and adhesive force of the product.
Description
technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing mortar with high bonding strength. Background technique [0002] In order to achieve the ideal 3D printing effect, the mortar used for 3D printing construction needs to have fast curing speed and high cohesiveness after leaving the delivery pipe, so as to obtain greater strength. However, the current construction mortar is viscous. The joint strength is poor and the plasticity is poor. The concrete commonly used in construction projects does not have the properties that can be used for 3D printing. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a high-bond strength 3D printing mortar, which is not only convenient to obtain materials and low in price, but also realizes the rational utilization of resources, and enables the product to maintain the plasticity of the mortar, ...
