Description
[technical field]
The present invention relates to a kind of transparent polyvinyl chloride section bar formula, relate to a kind of transparent polyvinyl chloride section bar formula being applied to LED rainbow light belt particularly.
[background technology]
LED (LED rainbow lamp) is widely used in the fields such as lighting engineering, decoration, ornament lamp moulding.Transparent flexible PVC material, because its transparency is high, perfect diffusion performance is good, easily processes, and is used widely in the production of LED with extruding-out process.
The most frequently used at present production technique of PVCLED light bar is secondary forming process: the first step, jointly extrudes, as wire and the carrier of LED with tinned wird and PVC plastic glue.Punching on wire, mounted LED lamp bulb.Be made into the heart yearn of LED.Second step, the first step heart yearn on be formed the pipeline of sealing again outside coated one deck.
The PVC plastic material aspect of current PVCLED light bar product, heart yearn material and coated material use general formulation, wherein softening agent DOP, lubricant stearate, and this general formulation exists following point:
1, plastic material does not have relevant criterion, and quality product is irregular, the non-meet the requirement of environmental protection of portioned product.
2, to weather resistance, as photoaging, water resistance do not have industry standard, no quantization index, the general aging resistance of resistance to climate of product is poor, and easy aging breakage, causes the wasting of resources.
3, adopt DOP to be softening agent (part producer also uses DBP) in general formulation, DOP, DBP are forbidden in Europe, the United States market and most of developed country.Product does not reach International Environmental Protection requirement.
4, adopt low-molecular-weight stearic acid to make lubricant, easily separate out, cause bad order and weather-resistant performance poor.Variable color, check surface, wrinkling.Meet after rainwater soaks and turn white.
5, work-ing life is short, within outdoor 4-6 month, namely occurs aging.
[summary of the invention]
The object of the invention is to overcome the deficiencies in the prior art, for the secondary forming process that PVCLED light bar is the most frequently used at present, consider environmental requirement and outdoor environment working conditions, the transparent polyvinyl chloride section bar formula that a kind of heart yearn material formula of the LED of being applied to rainbow light belt and coated material are filled a prescription different is provided.
The present invention for achieving the above object, by the following technical solutions:
Be applied to the transparent polyvinyl chloride section bar formula of LED rainbow light belt, it is characterized in that its heart yearn material comprises following parts by weight of component:
Its coated material comprises following parts by weight of component:
Be applied to the transparent polyvinyl chloride section bar formula of LED rainbow light belt as above, it is characterized in that described heart yearn material also comprises 0.004 part, whitening agent, pigment 0.002 part; Described coated material also comprises 0.004 part, whitening agent, pigment 0.002 part.
The heart yearn of LED and outer by all with transparent PVC plastics for base material.Adopt material substantially identical.Heart yearn in the present invention and outer by middle PVC resin powder, adopts universal SG-5, chooses transparency good, and the less trade mark of flake, impurity is then conducive to machine-shaping and has good outward appearance.
Be applied to the transparent polyvinyl chloride section bar formula of LED rainbow light belt as above, it is characterized in that the softening agent in described heart yearn material and described coated material is dioctyl terephthalate (DOTP).
Softening agent adopts DOTP, current European & American Market has limited the softening agent used containing phthalic ester, consider the ready availability of environmental protection and material, DOTP is the environment-friendly plasticizer of the maximum alternative phthalic ester (as DBP, DOP, DINP) of current output in domestic, and near DOTP, phthalic acid ester has better weather resisteant and dielectric strength.
Be applied to the transparent polyvinyl chloride section bar formula of LED rainbow light belt as above, it is characterized in that the thermo-stabilizer of described heart yearn material is organo-tin het stabilizer, the thermo-stabilizer of described coated material is composite calcium zinc stabilizing agent.
Be applied to the transparent polyvinyl chloride section bar formula of LED rainbow light belt as above, it is characterized in that the external lubricant in described heart yearn material and described coated material is PE wax.
Be applied to the transparent polyvinyl chloride section bar formula of LED rainbow light belt as above, it is characterized in that the internal lubricant in described heart yearn material and described coated material is polyhydric alcohol fatty acid ester.
General PVC light bar is out of doors under environment, meet rainwater to drench or soak for a long time, the thermo-stabilizer that sizing material includes and lubricant can with rainwater generation saponification reaction and produces White Flocculus in light bar inside, adding the low-molecular-weight lubricant of upper part is extracted out by water, forms white remain at frosting.Therefore the nonreactive organo-tin het stabilizer with water must be chosen to the thermo-stabilizer of heart yearn, the lubricant in formula also must select the PE wax and polyhydric alcohol fatty acid ester that molecular weight is larger.
Consider outdoor working conditions, outer by sizing material directly with extraneous contact, the acidic substance such as easy sulfur compound in air, rainwater, therefore organo-tin het stabilizer can not be adopted outward, be usually used in the barium of transparent PVC thermo-stabilizer, cadmium system stablizer owing to not meeting environmental requirement therefore not used.Therefore, what in formula, coated material adopted better performances take hydrotalcite as the NEW TYPE OF COMPOSITE calcium zinc stabilizer of stable nucleus, its permanent stability and weather resisteant better.
Be applied to the transparent polyvinyl chloride section bar formula of LED rainbow light belt as above, it is characterized in that the ultraviolet absorbers in described coated material is Benzophenones ultraviolet absorbers.
PVC is to daylight medium ultraviolet photaesthesia, and 300-400 nano waveband can accelerate the photolysis of PVC, adds Benzophenones ultraviolet absorbers in coated material, can reach the effect of light aging resisting.
Be applied to the transparent polyvinyl chloride section bar formula of LED rainbow light belt as above, it is characterized in that the whitening agent in described heart yearn material and described coated material is OB.
Be applied to the transparent polyvinyl chloride section bar formula of LED rainbow light belt as above, it is characterized in that the pigment in described heart yearn material and described coated material is ultramarine.
The LED rainbow light belt of post forming of the present invention compared with prior art, has following advantage:
1, plastic material is not containing heavy metal, not containing phthalic ester, meets existing International Environmental Protection standard;
2, good weatherability aging resistance is had: light aging resisting, under outdoor working conditions, long-time sun exposure, weathering drenches with rain light bar outward appearance without considerable change, and verify that modified formula can not turn yellow in 12-18 month through outdoor aging simultaneous test, surface is not separated out, do not chap, wrinkle resistant.
3, meet water not bleach, resistance to sulfide staining.
The present invention prepares different formulas according to the difference in functionality of heart yearn and outer quilt, makes PVC modified plastic rubber particle respectively, then according to existing complete processing, can produce better weathering resistance and meet the PVCLED light bar of environmental requirement.
