High-strength steel fiber adhesive and preparation method thereof

Abstract

The invention relates to the technical field of industrial buildings and discloses a high-strength steel fiber adhesive and a preparation method thereof. The high-strength steel fiber adhesive comprises the following components in parts by weight: 60-80 parts of a vinyl acetate-ethylene copolymer, 6-8 parts of polyvinyl alcohol, 15-20 parts of phosphorylated polyvinyl alcohol resin, 0.1-1.0 part of an amine cross-linking agent, 2-5 parts of an emulsifier and 5-10 parts of deionized water. The preparation method of the high-strength steel fiber adhesive comprises the following steps of: S1, material preparation; S2, preliminary dissolution; S3, primary mixing; S4, secondary mixing; and S5, tertiary mixing. The high-strength steel fiber adhesive is high in toughness, high in bonding strength, high in water dissolving speed and higher in anti-rust function, the amount of an adhesive for producing tandem steel fiber is small, and the cost of a product is reduced.

Description

technical field

[0001] The invention belongs to the technical field of industrial construction, in particular to a high-strength steel fiber adhesive and a preparation method thereof. Background technique

[0002] The construction industry is developing rapidly in many aspects, and the requirements for the strength of building concrete are also higher. In order to enhance the structural performance of reinforced concrete, the application of steel fiber has gradually become popular. After a long period of application, there are many disadvantages in the application of loose steel fibers. For example, in the process of concrete mixing, the loose steel fibers are intertwined to form a magpie's nest effect; the steel fibers cannot be dispersed evenly in the concrete, so that they cannot meet expectations. The purpose of the design is to improve the strength of concrete, so the replacement of loose steel fibers with row steel fibers is the first choice.
