Preparation method for flame retardant building block

Abstract

The invention discloses a preparation method for a flame retardant building block. According to the invention, the building block is prepared by adopting a high-temperature pressurization method, thusthe density and compressive strength of the building block are greatly improved, the high-temperature firing time is reduced, the energy is saved, and meanwhile the usage range of the building blockis expanded; and the sources of the raw materials of the product are wide, the production process is simple, the product quality and performance are significantly improved compared with those of a traditional building block, and spinel is added, so that the flame retardant effect is good.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a method for preparing a flame-retardant block. Background technique [0002] The current wall materials in our country have transitioned from traditional solid clay bricks to new wall materials. The new wall materials can be divided into three categories: blocks, bricks and plates in terms of use. At present, there is a large category of non-sintered concrete blocks among the new wall materials commonly used in China, mainly including ceramsite concrete blocks, ordinary concrete blocks, lime, cement, slag powder aerated concrete blocks, etc. These blocks are either poor in safety, especially organic polymer materials such as polyphenylene, which have a low heat-resistant temperature and are easy to burn, or have complicated processes and high costs. As a building block material for large-scale application, it must be considered whether it has good mechanical properti...
