Abstract

The invention discloses a green and environmentally-friendly building material and a preparation method thereof. The building material is prepared from, by weight, 90-110 parts of foamable thermosetting phenolic resin, 100-120 parts of thermosetting linear urea-formaldehyde resin, 3-5 parts of titanium dioxide powder, 90-95 parts of Tween, 20-25 parts of a modified acrylic emulsion, a filler, a cross-linking agent, and 10-15 parts of a composite assistant. The foamable thermosetting phenolic resin, the thermosetting linear urea-formaldehyde resin and modified acrylate are compounded, so the product combines the advantages of above three components, and is a novel building material with the advantages of smooth surface, good flame retardation and heat insulation properties, good strength and high cost performance.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a green and environment-friendly building material and a preparation method thereof. Background technique [0002] Green and environmentally friendly building materials, also known as ecological building materials and technical building materials, refer to healthy, environmentally friendly, and safe building materials. They are also called "healthy building materials" or "environmentally friendly building materials" in the world. It is an evaluation of the quality of "health, environmental protection and safety" of building materials. First of all, it has the properties of degaussing, noise reduction, dimming, temperature adjustment, heat insulation, fire prevention, and antistatic, and it is a special new functional building material that regulates human body functions. Green building materials refer to building materials that are non-toxic, non-polluting, non-radioa...
