Abstract

The invention provides a polymer building material for 3D printing. The polymer building material is prepared from a polyisocyanate ingredient (ingredient A) and a foaming and curing ingredient (ingredient B) according to the weight ratio of 1:1-1:1.50, wherein the ingredient B is prepared from 65 to 86 percent of hydroxy-terminated oligomers (containing hydroxy-terminated polyether, hydroxy-terminated polyester and the like), 8 to 15 percent of small molecule polyols, 0 to 10 percent of small molecule polyamine, 0 to 5 percent of fire retardants, 0.5 to 5.0 percent of catalysts, 0.5 to 5.0 percent of foam stabilizers, 0.1 to 4.0 percent of water and the like. The building material has the advantages of fast curing, high intensity, light weight, safety, environment protection, heat insulation, sound isolation, good waterproof effect, high fireproof performance and the like, and is particularly applicable to intelligent and automatic building 3D printing processes.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a rigid polyurethane foam material for 3D printing buildings. Background technique [0002] At present, most buildings use reinforced concrete and masonry as the main materials. This kind of material has many unavoidable disadvantages, such as high construction labor intensity, long period, high cost, etc., and due to the heavy weight of the building itself, it has high requirements for foundation treatment, which further increases the construction cost and construction period. More importantly, these traditional building materials have brought great damage to the natural ecological environment during the mining process, and not only consume a lot of energy during the firing process, but also produce a lot of environmental pollution. Among the "five small" enterprises that the Chinese government took tough measures to close down at the end of the last cent...
