Abstract
The present invention relates to the field of plastic product technology, in particular, it relates to the field of plastic product and its surface treatment technology. Said invented PVC sheet material is made up by using (wt%) 87-92% of PVC resin powder, 2-3% of stabilizing agent, 1.0-1.5% of lubricating agnet, 1.0-1.2% of processing adjuvant and the rest strengthening agent through the processes of high-temp. kneading, cooling, extruding, rolling and cutting, and on the surface of said PVC sheet material a layer of unsized protective film can be formed.
Description
Technical field
The present invention relates to the plastic products technology field, relate in particular to plastics and surface treatment thereof
Technical field.
Background technology
The PVC sheet material physical strength height of present common use, chemical resistance is strong, packs lightly, cheap, but this plate surface hardness is not high, easily scratches, and easily produces static, can adsorb dust and impurity in the environment, influences quality product.
Technical scheme
The purpose of this invention is to provide a kind of above-mentioned defective that overcomes, the PVC sheet material that can improve the quality of products greatly.
The present invention includes the polyvinyl chloride resin powder that accounts for total amount per-cent 87～92%, 2～3% stablizers, 1.0～1.5% lubricant, 1.0～1.2% processing aids, all the other are toughener; knead, coldly stir, extrude, roll, shear and process through high temperature, also be provided with one deck protective film without incohesion layer on the surface of PVC sheet material.
It is raw material that protective film without incohesion adopts with high-pressure polyethylene, line style high-pressure polyethylene, self-viscosity high-molecular polymkeric substance, and the layering ingredients mixture is through blown film, die head moulding, cooling, draw, peel off the new protective film without incohesion that makes.
Make production technique of the present invention comprise knead, cool off, extrude, press polish cools off to shear again and forms, and is provided with traction, applying program after press polish, 30～70 ℃ of binding temperatures.
The present invention can protect the surface of PVC sheet material effectively, has improved the quality of product greatly, and processing and manufacturing is easy, craft science, and subject range is more extensive, is widely used in instrument, the packing of the contour specification of quality of case and bag, print field.
Specific embodiments of the present invention:
Get the polyvinyl chloride resin powder that accounts for 88.55 parts, 2.5 parts of stablizers, 1.25 parts lubricant, 1 part of processing aid, 6.7 parts of tougheners are standby, the polyvinyl chloride resin powder is poured in the high speed machine stirred earlier, when temperature reaches 55 ℃ of left and right sides, add liquid adjuvants and continue to stir.Reach 75 ℃ in temperature.Add solid additive during the left and right sides and continue to stir, add processing aid and toughener again when temperature reaches 120 ℃, enter cold stirring when being cooled to 60 ℃ of left and right sides in the machine after stirring, discharge enters in the forcing machine.
The temperature in each district of forcing machine is set:
175 ℃ of 180 ℃ of IV of 175 ℃ of III of 170 ℃ of II of I, 165 ℃ of unitors;
The temperature of T pattern head is set at:
I?185℃ II?180℃ III?172℃ IV?168℃ V?173℃ VI?179℃ VII185℃。
Through the sheet material of press polish, through traction, in the time of 50 ℃, the new protective film without incohesion of patent applied for is fitted by contact pressure laminating apparatus, be cooled to room temperature again, make the novel PVC sheet material after shearing.
