Description
Technical field
The present invention relates to foaming polymer material, be specifically related to a kind of foaming polymer material special for vine art furniture and preparation method thereof.
Background technology
Back to nature is one of modern furniture development trend.The pure and fresh elegance of vine art furniture style, primitive simplicity and nature and do not miss the season have still fully been catered to the serious hope that the modern returns green nature, allow people's living environment be full of the rural area landscape.Natural rattan is the Palmae climber that grows in a kind of thorniness in the tropical forest, owing to porous light weight, color and luster natural beauty and very strong toughness, is widely used in the manufacturing of vine art furniture.But there is following problem in natural rattan all the time as one of main raw material of working out vine art furniture: easy mouldy long moth, and easy dry and cracked becoming fragile, yielding fading, therefore not long general duration of service with natural rattan Hepplewhite.In recent years, rise gradually, replaced traditional natural rattan in a large number with the imitative rattan that synthesized polymer material is made.Synthesized polymer material rattan fine and smooth, bright and clean, the environmental protection in surface in the market, compare natural rattan, have high strength, non-modification, colour-fast, not dry and cracked, durable in use, sun-proof, fire-retardant, mildew-resistant, mothproof, can be used for the indoor and outdoor, easy maintenance (cleaning) etc. with suds, but lost the characteristics of natural rattan surface natural grain and natural colored, made tone seem stiff unavoidably.The imitative rattan rice of common synthesized polymer material heavy (one meter weight) is between 10g～25g.Natural rattan has vesicular structure after because of dehydration, and its meter is heavy generally to be 8～10g, and therefore the imitative rattan of common synthesized polymer material is unfavorable for controlling the production cost of vine art furniture.Products such as vine art furniture with natural rattan and common synthesized polymer material rattan woven ware imitation system also have the hard partially shortcoming of sense of touch.
The present invention gains enlightenment from the characteristics of natural rattan, utilize absorbent polymer whipping agent and other auxiliary agent, overcome that common whipping agent can only make material foaming and the shortcoming that can not shrink, make the rattan post shrinkage of foaming earlier in process of production, form vesicular structure, natural grain and the natural colored of similar natural rattan, light weight and soft-touch, have simultaneously high strength, non-modification, colour-fast, not dry and cracked, durable in use, sun-proof, fire-retardant, mildew-resistant, mothproof, can be used for the indoor and outdoor, maintenance etc. easily.
Summary of the invention
The objective of the invention is to overcome the above-mentioned defective of prior art, a kind of foaming polymer material special for vine art furniture is provided, the present invention also provides a kind of method for preparing foaming polymer material special for vine art furniture.
In order to realize the foregoing invention purpose, in the technical scheme of the present invention, with the polyethylene is base material, add macromolecule foaming agent and other auxiliary agent, wherein the addition of polyvinyl resin is 25～90% with respect to whole blend quality, the addition of macromolecule foaming agent is 5～55% with respect to whole blend quality, the addition of compatilizer is 1～15% with respect to whole blend quality, ageing-resistant addition is 0.1～2% with respect to whole blend quality, the addition of nano-sized filler is 5～20% with respect to whole blend quality, the coupling agent consumption is 0.1～1% of mineral filler, and the addition of lubricant is 0.1～1% with respect to whole blend quality.
The preparation method of foaming polymer material special for vine art furniture of the present invention is: earlier with nano grade inorganic filler and coupling agent in homogenizer mixed after, add dispersing and mixing in proportion such as polyvinyl resin, macromolecule foaming agent, compatilizer, antiaging agent, lubricant again, feeder by delicate metering is sent into twin screw extruder, under twin screw conveying and shearing action, fully plasticizing, fusion, again through extrude, tie rod, cooling, drying, pelletizing and packing.
The length-to-diameter ratio of the twin screw extruder that uses among the preparation method of foaming polymer material special for vine art furniture of the present invention is 36～40, and is furnished with precise dose control and vacuum-pumping equipment.
Each section of the twin screw extruder extruder temperature that uses among the preparation method of foaming polymer material special for vine art furniture of the present invention should be controlled between 160 ℃～200 ℃, preferably at 180 ℃～200 ℃.
The present invention gains enlightenment from the characteristics of natural rattan, utilize absorbent polymer whipping agent and other auxiliary agent, overcome that common whipping agent can only make material foaming and the shortcoming that can not shrink, make the rattan post shrinkage of foaming earlier in process of production, resin belongs to absorbent resin, play foaming effect in process of production, the place that is different from traditional whipping agent is, this resinoid not only makes material foam in extrusion, and can make material in the foaming post shrinkage, make material surface form the natural grain and the natural colored of similar natural rattan; Form vesicular structure, natural grain and the natural colored of similar natural rattan, light weight and soft-touch, have simultaneously high strength, non-modification, colour-fast, not dry and cracked, durable in use, sun-proof, fire-retardant, mildew-resistant, mothproof, can be used for the indoor and outdoor, maintenance etc. easily.
