Description
Technical field
The present invention relates to building and ornament materials manufacturing technology, particularly relate to the cooling and shaping device and method that a kind of stone paper wallpaper base material is produced.
Background technology
Wall paper results from the mid-eighteenth century, and initial wallpaper draws on paper, prints various pattern and form.Have certain decorative effect, but be also only limitted to the senior places such as royal imperial palace do local decorate use.Real large area enters into life at home with other ornament materials, or from eighties late 1970s.A wallpaper development point three phases, the whole eighties, be foaming wallpaper period prevailing, " foaming " foams also known as half tone embossment.To the latter stage eighties, along with plastic cement industrial expansion, there is the substitute-glue surface wallpaper of foaming wallpaper.The nineties latter stage in 20th century, the wallpaper of woven design sense came into vogue to the early 21st century.From 2012, along with the mankind are for the growth of leisure, comfortable and environmental requirement, wallpaper development enters into the new stage, and the stone paper wallpaper of environmental protection, back to nature comes into vogue, and occuping market leading position.Producing wall paper by stone paper is a kind of environment-friendly type wall paper products grown up for nearly 2 years, the primary raw material of this product is Paris white and polyvinyl resin and other environment-friend auxiliaries, modified special material is produced through mixing, granulation, wallpaper base material is produced again through the forming technique such as casting machine, inflation film manufacturing machine, by coating, the technology such as cylinder printing produce the wallpaper of various fancy style.Now the forming technique of this wallpaper base material mainly be blowfilm shaping technique, temporarily also there is no a kind of fit closely method for processing forming, have the following advantages compared with other process by blow molding process forming method production wallpaper base material:
Equipment is simple, requires less investment while yielding quicker results.Compact equipment, floor space is little, and factory building cost is low.Shortcoming is: the film thickness uniformity is poor, and width deviation plays fold greatly, easily.Production line cooling is apart from short, and speed is low, output lower (for calendering).
Now with the stone paper wallpaper base material that film blowing method is produced, there is a lot of problem in whole wallpaper processing link, as unstable in: flower pattern, aberration is large, on wallpaper during wall to spending difficulty, having had the phenomenon of wrapping, these all increase difficulty of construction, have had a strong impact on the whole structure pasted.Therefore strengthen in the quality control difficulty of stone paper wallpaper production process, yield rate is low, seriously constrains production, and also make the class of product reduce, it is relevant with existing blowfilm shaping technology for tracing it to its cause, and namely the quality of stone paper wallpaper base material is relevant simultaneously.Present blowfilm shaping technology cooling, sizing are all realized by vane, and if patent No. CN201010212524.9 is a kind of stone paper film forming device and technique, refer to former is by extruder, and blown film device forms; The type of cooling of film pipe is also outer cold, with air blast and air-cooled vane.Material extrusion neck ring mold enters blown film section, in paper film pipe, be filled with compressed air, blown film, is stretched by traction, and peripheral air-cooled, sizing, offsets, and forms paper film base material.Stone paper wallpaper base material is in order to reduce costs, strengthen the sensation of paper, usually to add blowing agent to foam, after material extrusion neck ring mold, form the paper base material of fretting map, belong to free foaming during this forming method parison outlet mold, therefore this forming method also reduces the smoothness on surface while the grammes per square metre reducing wallpaper base material, bring difficulty to following process, product primary coat is made new advances white point and orange peel effect.Utility model patent 101850609A describes a kind of vane device for cooling film blowing machine, comprises main body, blast pipe and air outlet, it is characterized in that: the inside of described main body is divided into multiple space by shellring shape structure, and air holes that every layer of circulus is gathered.The patent of the cooling device through retrieving film blowing method is all be optimized or adjust in original vane structure, normal film class is produced and has positive effect, but produce for relatively thick stone paper wallpaper base material, these methods do not tackle the problem at its root.
Summary of the invention
Technical problem to be solved by this invention is, the cooling and shaping device and method that a kind of stone paper wallpaper base material that can control film bubble size and surface smoothness is produced is provided, wallpaper base material outside dimension is controlled to reach, solve because of the air-cooled product size wild effect caused, also solve the low drawback of wallpaper base material surface smoothness simultaneously, improve product percent of pass, reduce the object of production cost.
The technical scheme adopted is:
The cooling and shaping device that stone paper wallpaper base material is produced, is made up of a vacuum sizing device and two cooling devices.Two described cooling devices are two closed annular water or oil jacket, and described vacuum sizing device is ring seal room, and two annular water or oil jacket respectively two ends, connecting ring Shape closed room become an overall structure.
The annular water of above-mentioned cooling device or oil jacket are provided with multiple uniform water inlet or hydraulic fluid port and water outlet or hydraulic fluid port.
Above-mentioned water inlet or hydraulic fluid port and water outlet or hydraulic fluid port quantity the best can be 2-8.
The ring seal room of above-mentioned vacuum sizing device is provided with an interface be connected with vacuum machine, the indoor sidewall of ring seal offers aperture or the line style groove of regular distribution, and communicates with ring seal room, and hole diameter is 0.5-2mm, linear channel width is 0.5-2mm, and length is 2-80mm.Vacuum degree control is at 100-800mmHg.
The annular water of above-mentioned cooling device or oil jacket are consistent with the internal diameter of the ring seal room of vacuum sizing device, form by numerical controlled machinery equipment time processing, and annular water or oil jacket and ring seal indoor side surface roughness Ra reach 0.8-0.05 micron.
The ring seal room material used of the annular water of above-mentioned cooling device or oil jacket and vacuum sizing device is the wear-resisting tin bronze of high-quality or aluminium alloy.
The cooling and shaping method that stone paper wallpaper base material is produced, comprises the following steps:
Step one, obtains the filling-modified pellet of inorganic powder height by base material formulation material through mixing granulator;
Step 2, filling-modified for inorganic powder height pellet, foaming small powder are added in inflation film manufacturing machine after mixing and carry out blowing, when after parison outlet mold, traction parison therefrom between through cooling, shaping equipment, collapser and upper draw-gear, inflate in film bubble simultaneously, film bubble is propelled the price of and can touch cooling, shaping equipment inner surface;
Step 3, opens vacuum machine, regulates vacuum, is adsorbed on by parison on cooling, shaping equipment, opens cooling water or oily adjust flux, controlled cooling model speed;
Step 4, eventually passes crimping roller and is curled into product.
Cooling device of the present invention adopts water (oil) cooling to be the fastest a kind of cooling means, vacuum sizing device is best guarantee product size stability and the method for surface flatness, overcome traditional blow molding process air cooling, air quantity instability can produce base material width and to fluctuate large drawback, base material has produced the low phenomenon of bag, scollop, scallop and substrate surface smoothness, the present invention can ensure the absolute precision of stone paper wallpaper substrate sizes, substantially increases smoothness, improves product quality and yield rate.
