Abstract
The invention relates to a production method of modified red mud complexed polyvinyl chloride colorized rigid plastic. The method is characterized in that: graded red mud with a specification of -800 meshes is modified by using a titanate coupling agent; 35-45 parts of the modified red mud, 100 parts of polyvinyl chloride, 5-10 parts of an impact modifier, 3-5 parts of a stabilizing agent, and 0.2-0.8 parts of a lubricating agent are subject to high-speed mixing, melt extrusion and filming, such that the colorized rigid plastic is obtained. According to the invention, red mud is subject to a modification treatment, such that the compatibility of the red mud and polyvinyl chloride is substantially improved. When the plastic is subject to the filming treatment, a monotonic brownish red color of the red mud complexed polyvinyl chloride substrate plastic is changed, a woody pattern is provided, the color is diversified, and the plastic is provided with a good appearance.
Description
Technical field
The present invention relates to a kind of working method of utilizing the composite polyvinyl chloride color rigid plastics of red mud.
Background technology
Red mud is to produce the solid slag that produces in the alumina process with bauxite for the raw material alkaline process.The discharge capacity of red mud, composition and characteristic are different because of the variation of the kind of bauxite and production technique.Bayer process, every production 1 t aluminum oxide discharging red mud 1-1.5t.Sintering process and integrated process technology, every production 1 t aluminum oxide discharging red mud 1.5-2.5 t.According to statistics, global annual red mud produce total amount reach 7000 surplus ten thousand tons, wherein Chinese annual generation has more than 3,000 ten thousand tons.Though the red mud comprehensive utilization technique has been carried out extensive studies, the red mud utilization ratio is still very low, and the red mud comprehensive utilization ratio of China is merely 4%.
Red mud is mainly with mineral compositions such as sodium white residue, rhombohedral iron ore, diaspores, stable in properties, and the red mud particle is thinner in addition, and-800 hot eyes mud account for more than 70%, therefore possess the pacing items of doing plastic filler.But mostly the red mud surface functional group is active higher hydroxyl, shows as wetting ability, and oil number is big, and dispersiveness, consistency, wettability are all bad in Plastic Resin, therefore preferably it is being carried out surface-treated as before the plastic filler.In addition, because red mud plastic matrix color is a red-brown, color is dull, and is attractive in appearance inadequately, therefore red mud plastic changed colour, and processes colored and all kinds of Wood-grain-imitating patterns, will obtain liking of more users.
Chinese invention patent CN 101787227 A disclose a kind of working method of red mud filler; This method just simply is divided into 325 orders through cyclonic separator with red mud, 800 orders, 1250 orders; 5 grades in 2500 orders and 5000 orders are not done further modification to red mud and are handled.Chinese invention patent CN 1369515A discloses a kind of color processing method of red mud plastic section bar, and this method is soaked the red mud plastic section bar 4-160 minute in 75 ℃ of-100 ℃ of high-temperature water, or with 75 ℃ of-100 ℃ of high temperature gases heating 4-160 minute; Promptly from high-temperature water or high temperature gas, take out then; Handle through naturally cooling, the surface color of red mud plastic section bar is promptly changed into silver gray by scarlet, and this method is implemented simple; But can not solve the dull problem of color; And red mud plastic colour developing is red stone in the red mud, and 75 ℃ of-100 ℃ of pyroprocessing can not change its structure, therefore are difficult to guarantee the silver-gray stability of red mud plastic.China utility model patent CN 2633557 discloses a kind of polyvinyl chloride color plastic material; This section bar is characterised in that on the visible surface of common polychloroethylene section bar and merges that to have with the red mud powder be the brown PVC layer of weighting agent, and in fact the color that this colour section bar manifested is brown after red mud and the PVC fusion.
Summary of the invention
The objective of the invention is to develop the working method of the composite polyvinyl chloride color rigid plastics of a kind of changed red mud.
The objective of the invention is to realize through following technical scheme.
The working method of the composite polyvinyl chloride color rigid plastics of a kind of changed red mud is characterized in that may further comprise the steps:
(1) using air classifier is+800 orders and-800 order two portions with dried red mud grading;
(2) the dried red mud of-800 orders with step 1 gained places modifying machine, adds coupling agent and the heated and stirred modification of red mud dry weight 1%-2%, and modification temperature is 100-150 ℃, and modification time is 30min-60min;
(3) changed red mud of step 2 gained and SE, impact modifier, stablizer, lubricant mixed at high speed is even;
(4) the equal batch mixing with step 3 gained melt extrudes, and obtains the composite SE matrix of red mud plastics;
(5) the composite SE matrix of the red mud of step 4 gained plastics being carried out surface coating on the section bar laminating machine handles.
The working method of the composite polyvinyl chloride color rigid plastics of a kind of changed red mud of the present invention is characterized in that the coupling agent that said red mud modification is adopted is a kind of monoalkoxytitanates coupling agent.
The working method of the composite polyvinyl chloride color rigid plastics of a kind of changed red mud of the present invention is characterized in that said impact modifier is the interpenetrating network copolymer of chlorinatedpolyethylene and acrylic ester grafted formation; Stablizer is lead salt stabilizer or organotin stabilizer; Lubricant is Triple Pressed Stearic Acid or paraffin.
The working method of the composite polyvinyl chloride color rigid plastics of a kind of changed red mud of the present invention is characterized in that the composite SE matrix of said red mud plastics are made up of following mass percent: SE: 100 parts; Changed red mud: 35-45 part; Impact modifier: 5-10 part; Stablizer: 3-5 part; Lubricant: 0.2-0.8 part.
The working method of the composite polyvinyl chloride color rigid plastics of a kind of changed red mud of the present invention is characterized in that said overlay film is a base material film with the middle hardness PVC calendered film through grain printing, and hot compound one deck polyacrylic ester is processed through embossing then on it.
The working method of the composite polyvinyl chloride color rigid plastics of a kind of changed red mud of the present invention has the following advantages:
(1)+800 hot eyes mud alkali content is starkly lower than-800 hot eyes mud; Adopt the fractionated method that it is separated ,-800 hot eyes mud are done plastic filler through modification, and+800 hot eyes mud are because alkali content is very low; Can be as the raw material of material of construction such as cement, brick; So just can realize the comprehensive utilization and the high value added utilization of red mud, with respect to the technology of directly former red mud powder comminution being done plastic filler after thin, its energy-saving effect is fairly obvious.
