Problems solved by technology

The term concrete usually refers to the cement concrete obtained by mixing cement with cement as cementing material, sand and stone as aggregate, and water (may contain admixtures and admixtures) in a certain proportion, also known as ordinary concrete. Concrete is the most important material for building structures. It is widely used in roads, construction, decoration, heavy industry and other fields, but it is used in high load-bearing and high-impact environments. The compression, flexural and anti-corrosion properties of simple concrete materials The crack performance is low, and cracks are one of the most common diseases of concrete structures, which have a very adverse effect on the safety and durability of concrete structures.
[0003] Epoxy resin has excellent adhesion, stability, chemical resistance, insulation and mechanical strength, so it has become a polymer material commonly used in cement concrete modification, but epoxy resin is a thermosetting resin, and the degree of crosslinking High, poor flexibility and impact resistance, brittle and easy to crack

Abstract

The invention discloses a nanometer composite epoxy resin building material. The nanometer composite epoxy resin building material comprises 60 to 85 parts of cement, and 20 to 40 parts of an epoxy resin adhesive; the epoxy resin adhesive comprises, by weight, 80 to 90% of a composite epoxy resin, 6 to 10% of a curing agent, and 5 to 10% of a reactive diluent; after ring opening, a linear epoxy resin and 2,5-di(tetradecanoic acid ester) terephthalic acid are subjected to polymerization esterification so as to obtain an epoxy resin pre-modified body, aliphatic chains are introduced as flexiblechains, and linear epoxy resin flexibility is improved; nanometer modified cerium oxide is dispersed in the epoxy resin pre-modified body, so that acting force much higher than Van der Waals' force isachieved at the interface between nanometer modified cerium oxide and the hydroxyl and carboxyl of the epoxy resin pre-modified body, micro cracks and adsorption of energy are induced, epoxy resin system deformation is inhibited, and further toughening effect is achieved. When the nanometer composite epoxy resin building material is used in building materials, building material cracking possibility is reduced.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a nanocomposite epoxy resin building material. Background technique [0002] Concrete is the most important building structure material, which is widely used in roads, construction, decoration, heavy industry and other fields. Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. The term concrete usually refers to the cement concrete obtained by mixing cement with cement as cementing material, sand and stone as aggregate, and water (may contain admixtures and admixtures) in a certain proportion, also known as ordinary concrete. Concrete is the most important material for building structures. It is widely used in roads, construction, decoration, heavy industry and other fields, but it is used in high load-bearing and high-impact environments. The compression, flexural and ant...
