Description
Technical field
The present invention relates to a kind of method that improves synthetic paper intensity.
Background technology
The environmental protection synthetic paper is as novel paper kind, and the premium properties of environmental protection synthetic paper is more and more obvious, and purposes also more and more widely has been extended to many frontiers, and many product innovations constantly are developed.The environmental protection synthetic paper has had the development history of three more than ten years abroad; Along with the reinforcement of global environmental consciousness,, accelerated the development of synthetic paper because of the normal wood fibrous paper causes a large amount of pollutions; New environmental protection synthetic paper kind constantly occurs, and has enlarged the range of application of environmental protection synthetic paper.Originally synthetic paper is main with Vestolen PP 7052, adds a spot of stopping composition and processes, and strength of paper is very high, but cost is also very high.At present, the direction that the environmental protection synthetic paper is filled towards height develops, and the high result who fills is the strength degradation of synthetic paper, and the present invention is exactly in order to solve synthetic paper under the situation that height is filled, and the intensity of synthetic paper is unlikely to descend a lot.
Chinese invention patent CN102226022A discloses the method for manufacture of a kind of water-ground limestone and Vilaterm composite environmental-friendly paper; It is characterized in that: high density polyethylene(HDPE), water-ground limestone, tween, sodium oleate, antioxidant 1010 are joined in the Banbury mixer, reach 160～190 ℃ through banburying to temperature; Then the material after the banburying is sent in the forcing machine; Melt extrusion is sent in the rolling press through two roller mills; The working parameter of adjustment rolling press; Make the vertical, horizontal of the sheet material of extruder-calender reach the elongation at break of setting, the temperature of rolling press is controlled at 140～160 ℃, with sheet material cut edge, rolling; With the sheet material of the rolling unreeling machine of packing into, the sheet material after unreeling is sent in the multiple roll drawing machine, and sheet material is preheated to 110～130 ℃ earlier in drawing machine, stretches through 2～5 groups of draw rolls, obtains the environmental protection paper that needs.Using the density of resulting water-ground limestone of present method and Vilaterm composite environmental-friendly paper is 0.9～1.5g/cm3.
Chinese invention patent CN101457056 discloses a kind of synthetic paper coating; This coating comprises 10～20% waste polystyrene foam plastics, 20～30% kaolin, 50～60% toluene, 0.2～0.5% static inhibitor, 0.1～0.3% surface slip agent, 2～3% composite assistants, and above per-cent is mass percent.After in polystyrene foamed plastics, adding toluene, melt polystyrene foamed plastics being no more than under 150 ℃ the temperature, add composite assistant again, process AK modified resin; Kaolin and the AK modified resin that makes fully are uniformly dispersed, are ground to fineness≤15 micron then; At last surface slip agent, static inhibitor and ground material are uniformly dispersed together and promptly make synthetic paper coating.Synthetic paper coating is formed printable layer on the synthetic paper top layer, improve the printability of synthetic paper, make things convenient for synthetic paper to be suitable for general mode of printing and common ink printing, enlarge the use range of synthetic paper.
The present invention is employed in and adds vinyltriethoxysilane, Di Cumyl Peroxide 99 in the prescription, and Di Cumyl Peroxide 99 initiator decomposes in the Banbury mixer makes it to become the very high radical of chemically reactive continuously.The Wasserstoffatoms that these radicals are captured in the high density polyethylene(HDPE) molecule makes the high density polyethylene(HDPE) main chain become active radical; And then produce graft reaction with vinyltriethoxysilane, vinyltriethoxysilane is received on the molecular chain of high density polyethylene(HDPE).After synthetic paper is blown out; Through soaking in 80～90 ℃ the hot water; In the process of soaking, ethoxy group generation hydrolysis, silanol condensation formation-Si-O-Si-cross-link bond on the silane promptly obtain the crosslinked with silicane synthetic paper, thereby the intensity of synthetic paper are improved.
Summary of the invention
A kind of method that improves synthetic paper intensity; It is characterized in that: the automatic gauge scale through separately joins in the continuous Banbury mixer continuously respectively with high density polyethylene(HDPE), active water-ground limestone, vinyltriethoxysilane, Di Cumyl Peroxide 99, calcium stearate, Zinic stearas, antioxidant 1010; Control the weight proportion of each material through controlling the automatic gauge scale, the temperature of Banbury mixer banburying section is controlled at 130～160 ℃ continuously; Material after the continuous banburying is sent into the inflation film manufacturing machine system, and material is through screw extrusion press, and melt extrusion is through O die shape film forming pipe, and the film pipe is blown out synthetic paper with pressurized air under 120～130 ℃ temperature; Be divided into two through cutting knife, soak in the hot water that every warp is 80～90 ℃, the rolling respectively of oven dry back, the synthetic paper of the intensity that is improved.
