Description
Technical field
The present invention relates to building and decoration with the fire prevention section bar, relate in particular to a kind of microlite fire prevention section bar.
Background technology
In the present fire-retardant material component, most important fire-retardant composition is an Antimony Trioxide: 99.5Min, but it has radioactivity, and human body is had great harm and is unfavorable for environmental protection.And great majority fire prevention section bars also have aging fast, can distortion, the shortcoming of fire resistance difference.
Microlite; Devitrified glass just; Also be beautiful spar, lustrous and transparent spar, micro-crystal board material; Be called as micro-crystalline ceramic in the U.S.; Be called as sintered glass ceramics in Japan, be meant through parent glass and in heat-processed, control a kind of a large amount of microcrystals and Vitrea composite solid material of containing that crystallization makes.Compare with other natural stone; Devitrified glass because have compact structure, high-strength, freeze proof, do not absorb water, anti-erosion; In appearance clean mark, lovely luster, aberration is little and advantage such as fugitive color not, has become one of type material in numerous architectural decorative and fitting materialses.
Microlite is to choose several main components in the granite through high temperature, from the glass metal of special composition, separates out special crystalline phase.Therefore, have very high hardness and intensity, in moulding process again through the typing of the high-temperature fusion of secondary, therefore, the texture that does not have lithotome to form, so microlite neither easy fracture, do not absorb water, be not afraid of again and corrode and pollute, glossiness is also high.Can not occur aberration, the accumulation of salt in the surface soil behind the decoration, tell phenomenons such as juice, not need maintenance.
Existing market is not made the fire prevention section bar to microlite.Generally only be placed on integral cabinet and above the kitchen range top, existing microcrystal stone profile does not possess the fire retardant effect of national requirements.
Summary of the invention
In order to solve the problems of the technologies described above, the object of the present invention is to provide a kind of microlite fire prevention section bar, it does not comprise the radioactivity objectionable impurities, also has the fire resistance of good National standard.
For reaching said purpose, the present invention adopts following technical scheme:
The present invention provides a kind of microlite fire prevention section bar, and its main ingredient is heavy calcium carbonate powders and polyvinyl chloride resin, and other chemical assistants comprise one or more in aluminum oxide, antimonial lead, CPE, dibutylester and the one package stabilizer.
The weight proportion of said microlite fire prevention section bar is: water-ground limestone 50-70 part, polyvinyl chloride resin 20-40 part, other chemical assistants 5-25 part.
Preferably, 60 parts of said water-ground limestones, 25 parts of polyvinyl chloride resins, 15 parts of other chemical assistants.
Wherein said other chemical assistants comprise antimonial lead 1-5 part, CPE1-5 part, dibutylester 1-5 part, aluminum oxide 1-5 part and one package stabilizer 1-5 part.
Preferably, said other chemical assistants comprise 4 parts of antimonial lead, CPE4 part, 4 parts of dibutylesters, 1 part of 2 parts in aluminum oxide and one package stabilizer.
Antimonial lead: claim lead stearate again, as the working temperature of main thermo-stabilizer, stable carrier.
CPE (chlorinatedpolyethylene): as toughener, increase support strength.
Dibutylester: claim two fourth DBP again, as softening agent, enhancing smooth finish.
Aluminum oxide: substitute the Antimony Trioxide: 99.5Min that uses in the prior art.
One package stabilizer: can select for use this area to use one package stabilizer always, for example in preferred embodiment of the present invention used one package stabilizer available from the friendly product of rubber and plastic in Hengshui, Hebei three factory, model: FWR, operative norm: KIHSY01-2007.
The manufacture craft flow process of said microlite fire prevention section bar is: pulverize, mix, heat, granulation, moulding.Be that main raw material is equipped with other chemical assistants specifically, behind the High Temperature High Pressure sintering, obtain product through extruding-out process.
Microlite fire prevention section bar of the present invention can be widely used in fireproof door frame, fire prevention window frame and fireproof brickwork partition etc.
Microlite of the present invention fire prevention section bar has excellent fireproof performance, national wealth and people's life and property safety is played a protective role, for NFA and the section bar of preventing fires have been filled up blank.
