Abstract
The invention provides a polystyrene class A non-flammable micro-foam ceiling which is prepared by the following steps: mixing XPS, a cross-linking agent, a catalyst and a flame retardant and then extruding, stirring at the temperature of 100 to 120 DEG C, adding a foaming agent after stirring uniformly and then mixing uniformly, and adding the well mixed raw materials into a flat double-screw extruder and heating and mixing to obtain the finished product. The polystyrene class A non-flammable micro-foam ceiling meets the performance requirement of the ceiling, and is damp-proof and fire-resistant, the combustion performance reaches the national class A standard, and a surface crust is integrated with a closed foam into a whole. Due to the polystyrene class A non-flammable micro-foam ceiling, the heat preservation, fire resistance, thermal insulation, sound insulation, and decoration of the roof of a building can be implemented once so that second decoration is avoided, moreover, the polystyrene class A non-flammable micro-foam ceiling is simple and convenient to construct, and attractive and magnificent in appearance, thereby being the best decoration for an indoor roof.
Description
Technical field
The invention belongs to building material field, being specifically related to a kind of take polystyrene as the material of construction of base-material.
Background technology
Top ceiling is the general name to decorate indoor roof Material, and fire-protection rating requires higher for not fire A level.Be mainly used in the places such as airport, station, office building, market, subway station and house.Market there are plasterboard, mineral wool board, PVC, aluminum-pinch and soft smallpox etc.Gypsum plaster ceiling board is that main case raw material blast blending and fiber are made with the plaster of Paris, has light weight, thermal insulation, sound absorption, fire-retardant and the performance such as can to saw, but plasterboard integrated ceiling, easily split and distortion of making moist.Clamping plate (being also glued board) have that material is light, intensity is high, good elasticity and toughness, shock-resistant and vibration, the easily advantage such as processing and covering with paint, insulation.It can also create easily bending, circle, side etc. various moulding smallpox, but shortcoming is afraid of termite.The rectangular aluminum-pinch of abnormity is expensive, and house decoration does not re-use this kind of material mostly, mainly because it does not bear dirty and yielding.This smallpox of stained glass has multiple pictorial pattern, and means of illumination can be installed in inside, but general is decorated with local.If fit up by light steel keel gypsum board smallpox or clamping plate smallpox, when painting in its face, seam sealed by application terra alba, then with prime coat, japanning again after the sealing of ox-hide adhesive tape.Shortcoming is frangible, and it is high that installation is inconvenient to cut the high specification of quality to keel of weight.
Organic ceiling tile materials comprises PU material and PVC plastic etc., and wherein PVC suspended ceiling low price is handsome in appearance.Shortcoming is that fire-protection rating is low, not durable.This is determined by the performance of PVC material.
Summary of the invention
For the weak point of this area, the present invention proposes a kind of polystyrene A level and does not fire microvesicle top ceiling.
For realizing object of the present invention, concrete technical scheme is:
A kind of polystyrene A level does not fire microvesicle top ceiling, and it is stirred at 100 DEG C-120 DEG C XPS, linking agent, catalyzer, fire retardant, adds whipping agent mixing, added in flat Bitruder by complete mixed raw material and extrude after stirring.
Wherein, in raw material, the weight part of each composition is: XPS100 part, whipping agent 20-25 part, glue crosslinking agent 0.6-1 part, catalyzer 10-15 part, fire retardant 42-56 part.
Wherein, described linking agent is one or more in peroxidation two different and propyl benzene, benzoyl peroxide, peroxidation trimethylacetic acid tert-pentyl ester (TAPV).
Described whipping agent is one or more in Cellmic C 121, sodium lauryl sulphate (K12), polyoxyethylenated alcohol sodium sulfate (AES).
Described whipping agent is preferably Cellmic C 121.This whipping agent gas forming amount is little, and expansion ratio is 1-2 times, is suitable for preparing microcellular foam.
Described catalyzer is one or more in catalyst oxidation zinc, stearic acid, urea.
Wherein, described fire retardant is made up of oxidized petroleum wax 10-15 part of weight part, antimonous oxide 10-12, bisphenol a diallyl ether 12-16 part.
Further, described top ceiling, adopt following methods preparation and obtain: XPS, linking agent, catalyzer, fire retardant are carried out mixture by proportioning, stir at 100 DEG C-120 DEG C, whipping agent mixing is added after stirring, added in flat Bitruder by complete mixed raw material and carry out adding hot milling, foam shaping by extrusion is the sheet material of thickness 0.4-1cm.Sheet material length and width are 600cm usually
Twin screw extruder has " flat two " and " cone is two " two kinds, and equally large before and after flat Bitruder screw rod, pressure uniform, is applicable to the sheet material of extruded polystyrene material.
Product can arbitrarily can design compacting profile, printed patterns according to customer need, and gorgeous look novel, beautiful elegant in appearance.
Ceiling tile materials performance requriements is different from other building materials, because top ceiling is positioned at top, house, the gas temperature of contact is high, so require high to fire-protection rating, and also more water-fast.
Beneficial effect of the present invention is:
Products material proportioning science of the present invention, technique are simple, constant product quality.The product that the present invention proposes meets top ceiling performance requriements, and moistureproof, fire-resistant, combustionproperty reaches country's (A level) standard, and surface skining and closed pore foam combine together.Be applicable to the insulation of building roof, fire prevention, heat insulation, sound insulation, decoration be disposable puts in place, eliminate secondary decoration, construct simple and convenient, beautiful appearance is generous, is the best ornament of indoor roof.
