Abstract
A polyvinyl chloride (PVC) laminated soft sheet is prepared by the following raw materials by weight ratio: 90-110 of PVC resins, 15-20 of calcium carbonate, 30-40 of plasticizers, 3-4 of tribasic copper sulfate and 10-12 of paraffins. The laminated soft sheet is prepared by low toxic materials, has similar properties with the extrusion soft sheets, is widely used as a waterproof and anticorrosive material and can be also used as a flooring material. The laminated soft sheet has the following advantages: the sheet quality is superior to that of the extrusion soft sheets, and the laminated soft sheet can also use the recycled materials or reclaimed materials as the inner layer to lower the cost. The length specification of the laminated products is often limited by the size of the press.
Description
Technical field
The present invention relates to a kind of water-proof and anti-corrosive material, particularly a kind of polyvinyl chloride laminated soft sheet
The invention still further relates to a kind of preparation technology of this polyvinyl chloride laminated soft sheet.
Background technology
Polyvinyl chloride laminated soft sheet is a PVC soft sheet material of making certain specification after by prescription raw materials such as polyvinyl chloride resin, lime carbonate, softening agent, stablizer, lubricant being cooperated, through calendering, select sheet material according to the requirement of product thickness then, send in the laminating machine again after stacked, through hot-forming, cooling and shaping is made the PVC laminated soft sheet.Polyvinyl chloride laminated soft sheet of the prior art contains plumbous class toxic substance, can influence people's life security.
Summary of the invention
The technical problem to be solved in the present invention is at the deficiencies in the prior art, has proposed a kind of polyvinyl chloride laminated soft sheet safe in utilization.
Another technical problem that will solve of the present invention is a kind of preparation technology who proposes this polyvinyl chloride laminated soft sheet.
The technical problem to be solved in the present invention is achieved through the following technical solutions, and a kind of polyvinyl chloride laminated soft sheet is characterized in: it is made by following materials of weight proportions,
Polyvinyl chloride resin 90～110, lime carbonate 15～20,
Softening agent 30～40, three alkali formulas flow sour copper 3～4,
Paraffin 10～12.
The preparation technology of polyvinyl chloride laminated soft sheet of the present invention is characterized in:
At first film-making, to add in the operating high speed kneader by the starting material that prescription makes, kneading through 5～10min, when the material temperature reaches 140 ℃ of left and right sides, material is delivered in the Banbury mixer, carry out banburying when temperature of charge to 150 ℃～160 ℃, the material that draws off from Banbury mixer is sent in first open type plastic purificating set and is carried out mixing plasticizing, the temperature of plastics processing mill generally is controlled at about 150 ℃, should note stirring repeatedly in the operation, make plasticizing evenly, plastifying uniform material controls second again and closes on the open type plastic purificating set, make material continue plasticizing on the one hand, but main is to guarantee in time to three rollers or four-roll calender feed, the temperature of rolling press is controlled between 145 ℃～165 ℃, by rolling press material is rolled into the thick film of 0.5～1.0mm, the specification of sheet material can decide according to the size of finished product sheet material or press, be generally 1000 * 1900mm, send in the laminating machine after sheet material coincided by the thickness requirement of soft board, the surface that the stainless steel template contacts with sheet material must be polished to minute surface, and is smooth to guarantee finished product sheet material smooth surface;
Compacting then, during with steam heating press hot plate, heat imports tablet inside into from the tablet upper layer near the hot plate part earlier, and with about the steam heating 15min of lower pressure, vapor pressure is controlled at 3～4MPa earlier, use the steam heating of 7～8MPa then, make temperature reach 140 ℃～160 ℃, and be incubated 10～15min, get rid of the steam in the hot-plate then, open water coolant and make the hot plate cooling, when hot plate temperature drops to 40 ℃, get final product discharging.
The present invention compared with prior art, use the raw material of low toxicity to make, laminated soft sheet to extrude soft board and have similar character, be widely used as waterproof, impregnating material, also can be used as pavement, the advantage of laminated soft sheet is that plate face quality is better than extruding soft board, also available reclaimed materials or reworked material are made internal layer to reduce cost.The length specification of laminate product often is subjected to the restriction of press size.
Embodiment
A kind of polyvinyl chloride laminated soft sheet, it is made by following materials of weight proportions,
Polyvinyl chloride resin 90～110, lime carbonate 15～20,
Softening agent 30～40, three alkali formulas flow sour copper 3～4,
Paraffin 10～12.
The preparation technology of polyvinyl chloride laminated soft sheet of the present invention,
To add in the operating high speed kneader by the starting material that prescription makes, kneading through 5～10min, when the material temperature reaches 140 ℃ of left and right sides, material is delivered in the Banbury mixer, carry out banburying when temperature of charge to 150 ℃～160 ℃, the material that draws off from Banbury mixer is sent in first open type plastic purificating set and is carried out mixing plasticizing, the temperature of plastics processing mill generally is controlled at about 150 ℃, should note stirring repeatedly in the operation, make plasticizing evenly, plastifying uniform material controls second again and closes on the open type plastic purificating set, make material continue plasticizing on the one hand, but main is to guarantee in time to three rollers or four-roll calender feed, the temperature of rolling press is controlled between 145 ℃～165 ℃, by rolling press material is rolled into the thick film of 0.5～1.0mm, the specification of sheet material can decide according to the size of finished product sheet material or press, be generally 1000 * 1900mm, send in the laminating machine after sheet material coincided by the thickness requirement of soft board, the surface that the stainless steel template contacts with sheet material must be polished to minute surface, and is smooth to guarantee finished product sheet material smooth surface.
The compacting of soft board is to be relatively easy to.Owing to contain more softening agent in raw material, therefore available lower temperature and lower pressure can make the compound integral body that becomes of flat substrates fusion.In pressing process, during with steam heating press hot plate, heat imports tablet inside into from the tablet upper layer near the hot plate part earlier.Unlikely long for making tablet upper layer near hot plate be in the pyritous time, must be earlier with about the steam heating 15min of lower pressure, vapor pressure is controlled at 3～4MPa, use the steam heating of 7～8MPa then, make temperature reach 140 ℃～160 ℃, and be incubated 10～15min, get rid of the steam in the hot-plate then, open water coolant and make the hot plate cooling, when hot plate temperature drops to 40 ℃, get final product discharging.The working pressure of press, requiring at the beginning has higher pressure, the sheet material that coincides is compressed be beneficial to conduct heat, and the indicator pressure of general oil pump is more than 9.8MPa, and along with the rising of temperature, material begins to become viscous state, and pressure should drop to more than the 7.8MPa.When material just reaches viscous state, pressure release in a flash should be arranged, so that the gas evolution of savings in sheet material.Promoting has adhesive property preferably between sheet material.
