A2 grade EPS modified fireproof insulation board and preparation and using method thereof

Abstract

The invention discloses a preparation method for an A2 grade EPS modified fireproof insulation board, which comprises the following steps: A, processing and modifying the un-fireproof conclusion particles into A2 grade fireproof conclusion particles; B, processing the A2 grade fireproof conclusion particles into A2 grade fireproof boards; and C, processing the A2 grade fireproof boards into A2 grade fireproof insulation boards. The preparation of the A2 grade fireproof conclusion particles is that covering, infiltrating and coating a layer of nano composite fire retardant additives outside the first core inner layer as a second fireproof middle layer; covering, splicing and coating a layer of nano composite flame retardant additives outside the second fireproof middle layer as a third solidification outer layer; and covering, spraying and coating a layer of nano composite toughen additives outside the third solidification outer layer as a forth toughen layer. The method provided by the invention is simple in matching and easy to prepare, and based on the original polystyrene conclusion heat preservation and heat insulation function, the A2 grade fireproof boards into A2 grade fireproof insulation board is provided with A2 grade fireproof function, is pollution free, and the effect of beautify wall body is various.

Description

Technical field: [0001] The invention relates to the technical field of building materials, in particular to an A2 grade EPS modified fireproof insulation board and its preparation and use methods. Background technique: [0002] Wall insulation materials can save a lot of wall materials, improve wall insulation performance, save resources and reduce environmental pollution. Wall energy-saving and thermal insulation materials are classified according to their classification, including organic (such as benzene board, polystyrene board, extruded board, polystyrene foam board, rigid polyurethane foam, polycarbonate and phenolic, etc.), inorganic (such as perlite Cement board, foam cement board, composite silicate, rock wool, autoclaved sand aerated concrete block, traditional thermal insulation mortar, etc.) , polystyrene particles, etc.), thermal insulation and anti-cracking materials: (welded wire mesh, hot-dip galvanized steel wire mesh, mesh cloth) and so on. But in terms ...

AI Technical Summary

Problems solved by technology

In comparison, the use of expandable polystyrene foam insulation boards is currently the most cost-effective thermal insulation building material for building exterior wall insulation projects. The only disadvantage is that it is flammable and not fireproof, resulting in Many disasters and accidents have seriously affected its application, so that its use is completely banned due to choking and waste food, causing a large number of existing polystyrene foam insulation board processing factories to close down
