Grade A fireproof light thermal insulating decorative integrated plate and production process thereof

Abstract

The invention relates to a building material, and in particular relates to a grade A fireproof light thermal insulating decorative integrated plate and a production process thereof. The integrated plate related to the invention employs a high-quality fluorocarbon coated high-density cement fibreboard as a surface decorative layer; the middle layer of the integrated plate is formed from closed cell vitrified micro-bubbles in combination with a high-strength structural adhesive through binding at the normal temperature; and the bottom layer of the integrated plate is a porous cement board. After being dried and formed, the integrated plate is 3-10 cm in thickness, and prefabricated and formed in a factory; when in use, the integrated plate is fixed to a wall body through an anchoring component and pasting mortar; and the joints are sealed by a silicone adhesive, therefore, one-step completion of thermal insulation and decoration is realized. By employing an inorganic thermal insulating aggregate which is matched with an efficient binding system, the density of the thermal insulating layer of the product is less than 150 kg / m3, and the coefficient of heat conductivity of the product is less than 0.060 W / M*K; and the compression strength and the rupture strength of the product are better than those of the XPS (Extruded Polystyrene) plate; and the integrated plate is a novel energy-saving building material.

Description

technical field [0001] The invention relates to building materials, in particular to an A-level fireproof lightweight thermal insulation and decorative integrated board and its production process. Background technique [0002] The development of my country's building energy-saving work has been promoted from the cold northern and hot southern regions to the central and eastern regions with cold winter and hot summer and large temperature differences between morning and evening. With the increase of new promotion areas, the climate and ecological environment are different; especially to improve thermal insulation and energy saving The dual requirements of fire protection and building fire safety have met the Ministry of Public Security of the People's Republic of China "Notice on Further Clarifying Relevant Requirements for Fire Supervision and Management of Civil Building External Thermal Insulation Materials" (Gongxiao [2011] No. 65) and "Civil Building External Thermal Insul...

AI Technical Summary

Problems solved by technology

However, the construction process is complicated, and hidden dangers such as hollowing and falling off are often caused during construction.

Moreover, foam plastic products have a limited anti-natural aging time, and their service life is generally 8-15 years. After being discarded, they cannot be biodegraded, causing environmental problems such as "white pollution"

As for other cork boards, wood wool boards, honeycomb boards, etc., they are rarely used due to the consumption of natural resources and poor durability.

Inorganic thermal insulation and energy-saving materials, such as rock wool, glass wool, phenolic resin and other products, have poor bonding, complex construction, high cost, and some are harmful to health, so they are not suitable for thermal insulation of building envelope structures

Mortar products require on-site construction. The demand for labor is large, construction is limited, and a large amount of construction waste is generated. The density of inorganic mortar can reach 300 kilograms per cubic meter at the lightest. Although the thermal insulation performance can meet the requirements, it is extremely necessary to develop new ones. technology, new products

At present, all kinds of thermal insulation integrated boards on the market, before the No. 65 document, all use extruded polystyrene board (XPS) or expanded polystyrene board (EPS) as the insulation layer. After grade A, rock wool boards and phenolic boards are used to replace XPS and EPS boards. In this way, the structural strength of the integrated board is greatly reduced, and the safety and service time are greatly reduced.
