Inflaming retarding heat preservation plate and production technology thereof

Abstract

The invention provides an inflaming retarding heat preservation plate and a production technology thereof. The inflaming retarding heat preservation plate is prepared by feeding, mixing, and stirring a foaming agent, cement R, a foam stabilization enhancement agent, anti-cracking fibers and a water prevention agent, performing injection molding on the materials, foaming the materials, performing preliminary maintenance, demolding the materials, cutting the materials, maintaining a finished product and the like. No combustible substance is added into the inflaming retarding heat preservation plate from manufacturing to mounting; the inflaming retarding and heat resistance performance of a product is high; the inflaming retarding heat preservation plate has the outstanding characteristics of damp resistance, corrosion resistance, high temperature resistance, ageing resistance and the like; potential quality hazards such as swelling, cracking, falling and permeation in application of conventional engineering construction are avoided; furthermore, the problems that an outer layer is easy to crack and the like because of a poor fireproof inflaming retarding effect and contraction and deformation of a large area of heat preservation layer at high temperature are solved; and the later maintenance cost and the comprehensive cost are greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a wall insulation board and a production process thereof. Background technique [0002] At present, the materials of external wall insulation boards are: EPS polystyrene board, XPS extruded board, phenolic foam board, rock wool board. The installation of the above external wall insulation materials and products has complicated production process, long construction period, high labor intensity, and hidden quality problems such as bulging, cracking, falling off, and water seepage often occur after construction, especially in terms of fire and flame retardant requirements. It is more obvious that the large-area thermal insulation layer shrinks and deforms under high temperature, which leads to greater hidden dangers caused by cracking and falling off of the outer layer. [0003] At present, the commonly used foam cement is mostly sulfuric acid type or hydrogen peroxide typ...

Problems solved by technology

The installation of the above external wall insulation materials and products has complicated production process, long construction period, high labor intensity, and hidden quality problems such as bulging, cracking, falling off, and water seepage often occur after construction, especially in terms of fire and flame retardant requirements. It is more obvious that the large-area thermal insulation layer shrinks and deforms under high temperature, resulting in greater hidden dangers caused by cracking and falling off of the outer layer

[0003] At present, the commonly used foam cement is mostly sulfuric acid type or hydrogen peroxide type, the construction process is complicated, the installation and cutting are cumbersome, the corrosion is strong after installation, and the service life is short.
