Abstract

The invention provides an on-site pouring foaming building thermal insulation material and a preparation method and an application method. The building thermal insulation material is composed of an Amaterial, a B material, a base material and water, wherein the A material is prepared by mixing polyether polyol, triethanolamine, a foam stabilizer, waste paper fiber and inorganic fiber, the B material is a polyphenyl polyisocyanate, and the base material is prepared by mixing cement, an inorganic fine material, a water reducing agent, a foaming agent and the foam stabilizer. At the time of use,the A material is added to the base material on the site and even mixing is carried out, then the B material is added and even stirring is carried out, then water is added to make slurry, and on-sitepouring is carried out. The provided building thermal insulation material can be directly poured on the site to form self-supporting closed pores, has the characteristics of light weight, low cost, high strength, excellent thermal insulation performance and the like, is suitable for indoor and outdoor thermal insulation layers, partition wall plates, on-site pouring thermal insulation sandwich layers, various special-shaped thermal insulation pipelines and the like, belongs to novel energy-saving building materials, and is the best substitute for polystyrene foam boards.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation materials, in particular to a pouring-in-place foaming building thermal insulation material, a preparation method and an application method. Background technique [0002] Building energy saving mainly uses thermal insulation materials to reduce heat loss to ensure a constant indoor temperature, thereby reducing the energy used for heating or cooling. Due to the low thermal conductivity and good thermal insulation performance of organic thermal insulation materials, they are widely used in building energy conservation. However, organic thermal insulation materials have various disadvantages, such as the use of petroleum resources as raw materials, poor environmental protection, flammability, poor weather resistance, and easy aging. Especially with the deepening of popularization and application, the flammable defects of organic thermal insulation materials are gradually exposed...
