Abstract

The invention discloses a homogeneous modified fireproof heat insulation board. According to the heat insulation board, as kaolin mixed with hydroxypropyl methyl cellulose and silica sol serves as an inorganic cementing material, bonding strength between a cementing agent and organic particles as well as between the cementing agent and fibers is greatly improved, and bonding time is shortened; polypropylene fibers subjected to flame-retardant modification through zinc borate have excellent heat insulation performance and can be dispersed or bonded more easily, and the purpose of homogeneous modification is achieved; the fireproof and flame-retardant performance, smoke suppression performance, heat insulation performance, structural strength and the like of polystyrene particles modified and foamed through ammonium polyphosphate, glass beads and the like are all improved. The heat insulation board integrates the respective advantages of an inorganic fireproof heat insulation material and an organic heat insulation material, is good in fireproof heat insulation performance, resistant to water and aging, high in strength, light, porous and permeable to moisture and is a high-efficiency and high-quality environment-friendly economical product.

Description

A kind of homogeneous modification fireproof heated board

Technical field

The present invention relates to lagging material preparing technical field for building, particularly relate to a kind of homogeneous modification fireproof heated board.

Background technology

Building thermal insulation material fire takes place frequently in recent years, the fire line of lagging material have also been obtained further concern, heat insulation plate for building common at present is mainly divided into cement foaming insulation board, rock-wool heat insulation plate, intumescent fire-resistant material fireproof heated board and foamed concrete fireproof heated board etc., the even existence of warming plate of these kinds some be difficult to the defect meeting user demand, be in particular in inorganic heat insulation material ubiquity low strength, capacity weight, the problems such as water-intake rate is high, and EPS, XPS, although the organic insulation materials such as PU are in quality, there is advantage in the aspects such as thermal insulation, but its fire line is poor, easily agingly to catch fire, the shortcomings such as danger of combustion is large, therefore being badly in need of development one class, to have unit weight light, intensity is high, waterproof, fire prevention, the warming plate that thermal and insulating performance is good.

Summary of the invention

The object of the invention is exactly the defect in order to make up prior art, provides a kind of homogeneous modification fireproof heated board.

The present invention is achieved by the following technical solutions:

A kind of homogeneous modification fireproof heated board, this warming plate is prepared by the raw material of following weight part: phosphoric acid solution 1-2, water repellent agent 1-2, hydrophober 0.4-0.5, kaolin 60-80, zinc borate 1-1.5, polypropylene agglomerate 4-5, modified foaming agent 1-1.2, silica flour 300-400, Paris white 20-30, Vltra tears 4-5, benzene emulsion 10-15, water 200-250, silane coupling agent 0.1-0.2 that the silicon sol 20-30 that Expandable Polystyrene (EPS) masterbatch pellet 6-8, solid content are 30-35%, concentration are 30-40%.

Described modified foaming agent mixes composite making by the raw material of following weight part: sodium lauryl sulphate 2-3, ammonium polyphosphate 2-3, glass bead 5-8, nano-calcium carbonate 2-3, solid content are the silicon sol 4-5 of 20-25%.

The preparation method of described a kind of homogeneous modification fireproof heated board is:

(1) first zinc borate, silane coupling agent and polypropylene agglomerate are uniformly mixed, directly drop into subsequently in parallel dual-screw melting mixing forcing machine directly to extrude and be spun into the fiber that length is 8-10mm, diameter is 40-50 μm, the polypropylene chopped strand obtaining blending zinc borate is for subsequent use;

(2) expandable poly-styrene master batch particle, modified foaming agent are uniformly mixed in rear input pre-foaming machine and carry out pre-frothing process, after slaking, obtain modified polystyrene expanded beads;

(3) Vltra tears is dissolved in the water completely, add kaolin subsequently, phosphoric acid, silicon sol stir and make jelling agent, add step (1), step (2) and other leftover materials again, abundant stirring makes the complete blending dispersion of material even, eventually passes compression moulding, maintenance processing can obtain described warming plate.

The present invention is with blending Vltra tears, the kaolin of silicon sol is as inorganic coagulation material, greatly improve jelling agent and organic granular and interfibrous bonding strength, shorten the bonding time, and the polypropylene fibre after the flame-retardant modified process of zinc borate of blending has excellent heat-insulating property, more easily disperse to combine, reach the object of homogeneous modification, and through ammonium polyphosphate, granules of polystyrene fire protection flame retarding after the modified foamings such as glass bead, smoke-suppressing and heat retaining property, the performances such as structural strength are all improved, the composite insulation boards that the present invention prepares has inorganic fireproofing insulation material and organic insulation material advantage separately, fireproof heat insulating is good, water-fast ageing-resistant, high-strength light, porous moisture-inhibiting, to can yet be regarded as a kind of efficiently high-quality environmental protection and economy product.
