Problems solved by technology

What these examples have in common is that the first stage reaction of the product with the fire is very well controlled, however at higher temperatures in a sustained fire situation the polystyrene inside the product will melt, resulting in a foamy structure and possibly the entire product collapse of structure

Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with specific examples, but the invention is not limited to the following examples.

[0019] The wall thermal insulation slurry according to this embodiment is composed of the slurry main body and water, wherein the slurry main body is composed of the following components by weight: 500 kg of flame-retardant polystyrene particles; 200 kg of light calcium; 165 kg of gray calcium; Calcium 100kg; Hexabromocyclododecane 10kg; Latex powder 13kg; Methylcellulose 4kg; Ethylcellulose 5kg; Wood fiber 2kg; Glass fiber 1kg.

[0020] The preparation process of the above-mentioned wall insulation slurry is as follows:

[0021] (1) Preparation of flame-retardant polystyrene granules: 500 kg of polystyrene granules containing 10 kg of hexabromocyclododecane (commercially available) are heated and foamed by steam to form granules with a size of 3 to 5 mm;

[0022] (2) Stir the flame-retardant poly...

Abstract

The invention relates to wall insulating mortar, its preparation method and a grade A wall insulating material. The main body of the mortar consists of: 45%-55% of flame retardant polystyrene particle; 15%-25% of light calcium powder; 15%-20% of ash-calcium-powder; 8%-12% of heavy calcium powder; 0.8%-1.2% of hexabromocyclododecane; 1.2%-1.5% of emulsion powder; 0.3%-0.5% of methylcellulose; 0.4%-0.6% of ethyl cellulose; 0.15%-0.25% of lignocellulose and 0.08%-0.12% of glass fiber by weight. The flame retardant polystyrene particles, which are of 3-5mm in size, are prepared by steam heating and foaming polystyrene particles containing 1.5wt%-2.5wt% of hexabromocyclododecane. In the invention, an insulating material with a combustion performance reaching the indexes of grade A noncombustible materials can be obtained. And the material provided in the invention is safety and fireproof, thus especially suitable to be used as external wall insulating materials.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a wall thermal insulation slurry, a preparation method thereof and a non-combustible wall thermal insulation material. Background technique [0002] Wall insulation material is a new type of wall material developed in recent years, which can save a lot of wall materials, improve wall insulation performance, save resources and reduce environmental pollution. During the "Ninth Five-Year Plan" period, new wall insulation materials entered a stage of rapid development, and now they have developed on a large scale; Cities and towns extend, extend to the countryside, and extend to industrial buildings. As far as the new wall materials mentioned in the national policy are concerned, there are hollow blocks, aerated blocks, gypsum hollow blocks, aerated fly ash bricks, porous clay bricks, GRC wall panels, reinforced fiber cement boards, sandwich Board, fly ash ae...
