Preparation method and application of chloroprene-rubber-adding building material

Abstract

The invention discloses a preparation method and application of a chloroprene-rubber-adding building material. The method comprises the following steps of processing Portland cement, perlite powder and sepiolite into powder through ball milling; performing calcination; then, adding modified carboxyl polyester resin and a mixture of polyacrylamide, cellulose acetate-phthalate and polyphenyl thioether subjected to ultrasonic processing for simultaneous heating reaction; then, performing a series of specific processes such as mixing, vulcanization, crushing, stirring, injection molding and heat insulation aging to obtain a finished product of the building material. The prepared building material has the advantages that the toughness is sufficient; the intensity is high; good application prospects are realized. Meanwhile, the invention also discloses application of the building material prepared by the preparation method to building wall body materials.

AI Technical Summary

Problems solved by technology

Although it has the advantages of high strength and good durability, it also has the disadvantages of low tensile strength, poor toughness, and difficulty in controlling the width of cracks after cracking. engineering accidents often occur

Cracks in concrete structures directly affect the durability of the structure and the service life of the project, eventually leading to premature deterioration of the concrete structure or even complete loss of function

In order to overcome these shortcomings of concrete, polypropylene fiber concrete and steel fiber concrete have emerged as the times require. The fiber content of this type of concrete is usually less than 2%. Although this can reduce the early cracking of concrete to a certain extent and improve the flexural toughness of the material However, strain softening damage still occurs under direct tensile load, and the crack immediately enters the stage of localized expansion after cracking
