Description
Technical field
The invention relates to curtain resin tubule, the particularly curtain of producing natural flavour mountaineous tubule and utilizing tubule to make with expanded polypropylene resin, and the manufacture method of relevant tubule.
Background technology
The curtain made from natural materials such as reed, bamboos is used in sunshade widely.But the tubule that is used for curtain at present is because of adopting materials such as PVC or polypropylene, so because its production efficiency height and stay in grade are used very general.But tubule surface smoothings such as PVC, brightness is arranged, natural sensation can't be arranged.It is contained that the manufacture method of natural texture is opened clear 60-No. 227714 communiques just like the spy, and resin forms the curtain tubule of ring shape through two runners of male and female.The spy opens the curtain tubule of putting down in writing in clear 60-No. 227714 communiques, and is concavo-convex bigger, and that its outward appearance is not had is natural flavour mountaineous for surface reflective.This is to have the product of natural flavour mountaineous texture different with the surface.
Also have resinous packaging material are used in packaging for foodstuff, but above-mentioned institute says that it has an even surface and produces reflective resin tubule to the high-grade inadequately sensation of people.As using natural material, administration of health is difficult for again.
When this tubule is produced, because of shape is identical, produces easily and also extrude easily, but natural sensation will be arranged, shape is not quite similar, and just is difficult for extruding.Moreover the tubule of surface smoothing is drawn out easily.There is the tubule of natural texture uneven,, brings difficult to processing so be difficult for being drawn out.
Summary of the invention
The present invention is for addressing the above problem, proposing a kind of tubule and manufacture method thereof of producing easily and having natural sensation.
The problems referred to above can solve with the tubule of expanded polypropylene resin manufacturing, and resin thin external diameter of pipe d is that the ratio (t/d) of 2.5～10mm and tubule wall thickness t is 0.02-0.2, and hardness is moderate and in light weight.For possessing the hardness of natural appearance and appropriateness, outward appearance proportion should be 0.7～0.95 simultaneously.
Resin thin tube-surface of the present invention has trickle vertical line and irregular asperities, makes it have natural flavour mountaineous and tubule is difficult for being drawn out.
Resin thin pipe manufacturing method of the present invention is, acrylic resin and blowing agent are put into extruder, and dissolving mixes extrudes from the mould of ring-type export department, is directed to cooling bath, cooling curing, and get and need length to cut off again.So promptly can be made into the efficient height and natural flavour mountaineous tubule is arranged.
Foaming agents content in the aforementioned base materials is 0.05～0.5 percentage by weight, natural outward appearance is arranged and keep appropriate hardness.Extruded velocity is 10～100 meters/minute in addition.The ratio (d/D) of the outer diameter D of aforementioned mould outlet portion and the outside diameter d of resin tubule is 0.2～0.8.These two kinds of methods are the natural flavour mountaineous resin tubule of the most suitable manufacturing.
Moreover, above-mentionedly be woven into curtain with the resin tubule, can be used for shading and interdict sight line or be used for packaging for foodstuff etc.
The present invention makes the resin tubule with expanded polypropylene, and composition preferably has only polypropylene, but also can as adding other resin under the situation that does not harm effect of the present invention.This acrylic resin can cooperate various additives to use.
Blowing agent promptly is wherein a kind of in the raw material that can be used, and the kind of blowing agent is not limit, and boiling point also can at the volatile foaming agent that melts below the forming temperature.The decomposition-type foaming agent that at high temperature can resolve into gas is also passable, and the requirement simple in structure of mixing arrangement uses decomposition-type foaming agent best.The amount of blowing agent is that 0.05～0.5 percentage by weight of all raw materials is the best, and the smooth of surface can't be removed when blowing agent was not enough, so be best more than 0.1 percentage by weight, but foaming dosage is too high, frothing percentage is excessive, and tube wall can break, tubule hardness deficiency.Therefore be the most appropriate below 0.3 percentage by weight.
Can use reed, bamboo and wood that color is all arranged.Adjustable natural material color makes its outward appearance more near natural colour.In also available color aspect shading, the confidentiality its performance is improved in addition, the kind of pigment and amount can be done appropriateness adjustment according to purpose.
Moreover inorganic filler is also passable, and calcium carbonate, mica powder etc. can be used.Improve confidentiality, increase skin-friction coefficient, in the filler with low-cost calcium carbonate for the most suitable, use level is 20-30 percentage by weights of full raw material.
Light-proofness, it is better that the situation of daylight direct irradiation adds ultra-violet absorber, can make curtain more durable like this.Ultra-violet absorber does not have special restriction.
Above-mentioned raw materials is made resin tubule of the present invention after melting.Usually use extrusion molding, can constantly make tubule, raw material is put into extruder after mixing.For asking steady quality, all raw materials are put into mixer and are mixed, when the polypropylene micelle uses with the powdery blowing agent, the micelle surface topped blowing agent powder want even.As better with the meeting of stirring oil, mixing time is more than ten minutes, and so blowing ratio is more even.
Can adopt raw material to put into extruder makes its thawing mixing extrude methods such as cooling cut-out again.
Melt temperature is to get final product more than the polyacrylic melting point, and the temperature during severing rises and also must consider.Want the state of appropriateness foaming, set so will note the temperature of extruder barrel, mould is a tubule moulding usefulness, and at this moment, mold center will blow, and makes tubule keep definite shape.The shape of ring-type export department does not limit.Product with column type preferably exports with the ring-type type.The export department's outer diameter D of mould and the ratio of tubule outside diameter d are 0.2～0.8, and rate value is little promptly can to produce vertical lines.The suggestion rate value is more than 0.3 below 0.5.
The thawing resin of extruding makes its sclerosis through cooling bath.The cooling bath kind is not limit, and is best with water-cooled, uses roller the best when tubule is pulled out, and speed is more than 10 1 100 meters/minute, and preferably more than 30 meters/minute, the speed more than 100 meters/minute can make the tubule fracture, and is therefore best below 70 meters/minute.
The tubule of extruding cuts off according to certain size, normally 100-300cm, and then being cut into required size according to its purposes, the length of tubule is to decide according to purposes, when being used for shading, sun-proof or interior decoration, be generally about 30-270cm, when being used for the packaging for foodstuff purposes, be generally about 5-40cm.
The tubule outside diameter d is 2.5～10mm, and preferably more than the 3mm, the ratio of following outside diameter d of 6mm and thickness of pipe wall t is 0.02～0.2, and hardness is enough and light again, and ratio is preferably in below 0.1 more than 0.04.
Outward appearance proportion is 0.7～0.95, and polyacrylic proportion is 0.9, and natural outward appearance is arranged, and hardness is suitable, adds an amount of inorganic filler, about acomia blister attitude proportion is 1.The proportion of foaming tubule of the present invention is littler than there not being foaming, so can be made into the tubule of 0.7-0.95 proportion, frothing percentage (volume of air content) can not calculated with the difference in specific gravity of foaming tubule from there being the foaming tubule.So calculating frothing percentage is below 30%, and if can reach 20% can be better, surpasses 30%, and tubule hardness is not enough, and curtain can be out of shape.Frothing percentage is relatively good more than 2%, and as better in meeting more than 5%, frothing percentage can be not obvious at the concaveconvex shape on surface below 2%.
Resin thin tube-surface of the present invention has vertical microgroove road, and this can make the tubule surface appear to the fiber of natural material, and lines is that 1mm has 5.Moreover, have irregular concavo-convexly, the light that this can reduce the surface seems that natural beauty simultaneously can make the tubule difficult drop-off.
Like this made resin tubule of mode is promptly to become curtain after the braiding of latitude bar with the resin tubule, and warp generally sees and use cotton thread, or the warp of cotton and polyester cotton etc., the warp upper and lower side applies glue, and the resin tubule can not come off.As when being used for the packing of " fish plate ", need not weave, just fasten with glue.As with resin tubule of the present invention, also can use, and have identical visual effect when being used for above-mentioned packing.
But be used on the curtain except block sunlight, cover beyond the invisible, be more suitable for interior decoration.Usually available plastic rail about, and load onto suspender, wide good fortune is 30～270cm, length is that 40～280cm is for the most common.Curtain of the present invention is promptly regulated the function of light except that the circulation of air that appropriateness is arranged, and is relatively good to eyes, can produce happy and auspicious atmosphere.Therefore it is also very suitable to be used for shop decoration or advertisement, can promote the image that the shop is commodity with this material.
In addition, use on the packaging for foodstuff purposes, do not add plastic rails up and down, have only the resin of using tubule.Size is generally wide 5-40cm, length is 10-60cm, and the thing of packing has fish plate, Japanese sweets, present.Can certainly be as the packaging material beyond the food.
