Description

A kind of wall decorating veneer
Technical field
The invention belongs to building material field, and in particular to a kind of wall decorating veneer.
Background technology
Building energy conservation be alleviate energy shortage, solve socio-economic development and energy supply it is insufficient this to the most effective of contradiction One of measure.With respect to other energy-saving building technologies, the superiority of external wall outer insulation is substantially avoided that generation building heat bridge, avoids interior Metope winter condensation is advantageous to protect agent structure, greatly reduces temperature stress and structural damage is acted on, increase structural life-time. Heat preservation decoration integrative system is produced, field installation process, favorably on the basis of External Thermal Insulation Technology for External using prefabrication In improving building industrialization, the standardization of products, construction assembling level, shorten the construction period.
PET (PET) fiber has excellent physical and mechanical properties, be widely used in clothes, The fields such as blanket, decoration, bedding, turn into the chemical fibre kind that application is most wide, consumption is maximum.But the pole of PET Limited oxygen index is only 21%, belongs to flammable fiber, greatly limit its application, it would be desirable to which its fire resistance is improved.
Patent CN106968049A discloses fire-retardant acoustic tile and its production technology based on Polyester Fibers, with useless Old plastics are raw material, regenerative polyester staple fiber, regeneration low melting point Skin-core type terylene chopped fiber are made through melt spinning, in sheet material sheet The upper surface of body uniformly sprays fire retardant, and bottom surface section thickness dipping fire retardant, cold wind cools after prebake, press polish, cuts Fire-retardant acoustic tile is obtained after cutting, but this fire-retardant agent method of spray simply carries out flame retardant treatment, flame retardant effect in superficial layer It is not very high；And a kind of wall decorating veneer is provided in the present invention, using green halogen-free flame retardants, by copolycondensation technology and Solid phase polycondensation technology is prepared for the fire-retardant PET resin of intramolecular, while silica modified body disperses more uniformly in the base, And exist with nano micropore structure, the conduction and heat radiation of heat energy in the material can be blocked, effectively lifts the resistance of material Fire performance.And the silica dioxide granule after silane coupler modified alleviates agglomeration, nanometer particle is dispersed into, can More effectively strengthen anti-flammability.
The content of the invention
It is an object of the invention to provide a kind of wall decorating veneer, using green halogen-free flame retardants, passes through copolycondensation technology The fire-retardant PET resin of intramolecular is prepared for solid phase polycondensation technology, while silica modified body is scattered more equal in the base It is even, and exist with nano micropore structure, the conduction and heat radiation of heat energy in the material can be blocked, effectively lifts material Fire resistance.
In order to achieve the above object, the technical solution adopted by the present invention is：A kind of wall decorating veneer, filled for inner wall of building Decorations, including substrate and hot pressing the PET on substrate, the thickness of the substrate are 10-15mm, the thickness of the PET For 1-3mm；
Wherein, the substrate is formed by 65-75%PP fibers and 25-35% glass fibre thermoplastics；
Wherein, the preparation method of PET is as follows：
1) it is 1 to take ratio:1:0.4 terephthalic acid (TPA), ethylene glycol and 2- carboxyethyl phenyls hypophosphorous acid carries out ester at 250 DEG C Change reaction, after reacting 40-70min, into polycondensation phase, for temperature control at 280 DEG C, vacuum is maintained at 10-12Pa；Polycondensation is anti- Flame-retardant PET resin is obtained after the completion of answering；
2) take silica with parts by weight relative to the Flame-retardant PET resin obtained in the step 1) that silica is 3-5% Successively it is put into high-speed mixer and mixed at high speed is uniform, incorporation time about 5min, is then tested by double-screw extruding pelletizing Machine is granulated, and Flame Retardant PET Fibres are made.
Preferably, the silica is nano silicon, particle diameter 15-60nm.
Preferably, by silane coupler modified, method of modifying is the silica：Nano silica powder is existed 100 DEG C of dry 24h in vacuum drying chamber；Dried silica is taken to be mixed with 1-METHYLPYRROLIDONE, ultrasonic disperse 30min, silane resin acceptor kh-550 is added in ultrasonic procedure, react and obtain modified nano silicon after 4-6h and disperse Liquid；Modified precipitation of silica is come out by centrifuging, is placed in 60 DEG C of baking oven and dries.
The beneficial effects of the invention are as follows：
1. using green halogen-free flame retardants, it is fire-retardant that intramolecular is prepared for by copolycondensation technology and solid phase polycondensation technology PET resin, compared with common PET fiber, fire resistance fibre crystallinity declines so that the dyeability of fiber improves.Flame-retardant PET is fine Dimension has very excellent fire resistance, and for limited oxygen index up to 35%, fabric leaves the function with self-extinguishment after burning things which may cause a fire disaster.
2. being more than simple blending in system, between particle filled composite and polymer, but there is chemical key connection.So After one side nano-particle and strand are with chemical bonds, molecular chain movement is made the thing between strand by restraining function Reason entanglement point is reduced, and equivalent to the class crosslink density for reducing polymer melt, causes melt viscoelasticity to decline.It is smaller in concentration When modified Nano more uniform can be dispersed in, do not chemically reacted with molecule, very little had an impact to molecule segment.Together When silica modified body disperse more uniformly, and with nano micropore structure to exist, heat energy can be blocked in material in the base Conduction and heat radiation in material, effectively lift the fire resistance of material.
Embodiment
With reference to specific embodiment mode, the present invention is described in further detail, to make those skilled in the art join Book word can be implemented according to this as directed.Obviously, described embodiment is only part of the embodiment of the present invention, rather than entirely The embodiment in portion.
