Abstract

The invention discloses an artificial lightweight material and a preparation method and application thereof. The artificial lightweight material is made from, by weight, 67-100 parts of a mineral material, 0-8 parts of a foaming agent, 0-20 parts of a mineral aid, and 0-5 parts of additives. The artificial lightweight material is prepared by converting an orthosilicate mineral from various steadystructures to a single nonsteady structure by means of high-temperature phase reconstruction of silicate minerals under the action of high temperature through the synergy of a mineral aid and additives. The artificial lightweight material is suitable for, but not limited to, insulation materials, decorating materials, insulation decorating materials and concrete light aggregates. The artificial lightweight material has light weight, high strength and good properties and is widely applicable; the materials are rich and environmentally friendly; the preparation method of the artificial lightweight material is simple and feasible and has low cost.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an artificial lightweight material and its preparation method and application. Background technique [0002] The building material industry is a basic industry for national construction, which has the characteristics of large volume, wide application, and variety of varieties. Traditional inorganic building materials and their products often have shortcomings such as large specific gravity, high thermal conductivity, and high water absorption, which limit their use in deeper and wider areas. field applications. New inorganic materials with performance characteristics such as light weight, high strength, low water absorption, and low thermal conductivity are the common demands of building structures, decoration, and thermal insulation materials. They represent the development direction of building materials and have broad application prospects. Contents of...
