Description
Technical field
The present invention relates to building material field, more particularly to a kind of new fire retardant exterior wall decorative panel and preparation method thereof.
Background technology
At present, decorative panel used for building exterior wall is generally the ornamental stones such as marble, granite, and its aesthetic property is preferable.But these materials
Matter proportion is larger, heat preservation and soundproof poor performance.In order to more effectively save the energy, foaming plate is also used in more and more widely
On decorative plate of outer wall.Meanwhile for the flame-retardancy requirements also more and more higher of similar foaming plate
The present invention relates to a kind of preparation of new fire retardant exterior wall decorative panel, this method using extrusion technique, by polyvinyl chloride,
The bio-based materials such as foaming agent, inorganic combustion inhibitor and wood powder or inorganic filler blending extrusion foaming plate, as base material, coextrusion
Surface layer is uvioresistant resin.Fire retardant exterior wall decorative panel prepared by the present invention is fire-retardant, insulation, sound insulation, environmental protection, attractive in appearance, uvioresistant.
There is good application prospect in decorating outer wall of building plate field.
The content of the invention
In view of this, it is an object of the invention to by polyvinyl chloride（PVC）With bio-based materials or inorganic filler, foaming agent, nothing
Machine fire retardant is blended, extrusion foaming sheet material, in extrusion, sheet material coextrusion uvioresistant resin surface layer, can effectively be applied
In decorating outer wall of building
Based on above-mentioned purpose, hollow extrusion prepared by the present invention goes out Side fascia, is made up of following raw material according to respective weight：
Polyvinyl chloride（PVC）100 parts, 5 ~ 80 parts of bio-based materials or inorganic filler, 3 ~ 8 parts of foaming agent, 5 ~ 100 parts of inorganic combustion inhibitor.
Its co-extrusion surface layer is uvioresistant resin
Preferably, described bio-based materials or inorganic filler be the bio-based materials such as wood powder, bamboo powder, powder of straw, calcium carbonate or
Inorganic filler
Preferably, described foaming agent is azo-compound, N- nitroso compounds, hydrazide kind compound and compounding foaming agent
Etc. foaming agent common in industrial production
Preferably, described uvioresistant resin surface layer is acrylonitrile-styrene-acrylic rubber (ASA), poly-methyl methacrylate
Ester（PMMA）Etc. uvioresistant resin
Preferably, described inorganic combustion inhibitor is one or more compoundings in the fire retardants such as magnesium hydroxide, aluminium hydroxide
In order to solve the above technical problems, the present invention proposes following technical scheme, it comprises the following steps：Step 1：By set
Dosage weighs each raw material, the i.e. mass parts of polyvinyl chloride 100, the mass parts of foaming agent 3 ~ 8, bio-based materials or inorganic filler 5 ~ 80
Part, 5 ~ 100 parts of inorganic combustion inhibitor；Step 2：By the polyvinyl chloride weighed, foaming agent, bio-based materials or inorganic filler, inorganic
Fire retardant is placed in high-speed mixer and mixed；Step 3：Mixed material is extruded fire-retardant in plate-extruding machine in step 2
Foaming plate, and uvioresistant resin surface layer is coextruded, and cut and receive side
From the above it can be seen that obtained according to the formula provided by the invention for preparing fire retardant exterior wall decorative panel and preparation method
Fire retardant exterior wall decorative panel, while its performance attractive in appearance is ensured, cost can be reduced, strengthen uvioresistant, insulation, sound insulation,
The performance such as fire-retardant, comply with the trend of sustainable development.The sheet material later stage can be carried out at thermoplastic pattern in uvioresistant surface layer
Reason, to increase aesthetic property.In addition, micro or a small amount of functional aid, such as plasticizer, antioxidant, colouring agent, thermostabilization
Agent etc. does not interfere with the basic technology and performance of the hollow energy-conserving Side fascia
Brief description of the drawings Fig. 1 is fire retardant exterior wall decorative panel sectional schematic diagram；
In figure：1 is polyvinyl chloride/bio-based materials or the flame-retardant expanded composite plate of inorganic filler；2 be uvioresistant resin surface layer；3 are
