Abstract
The invention discloses an environment-friendly type coated paper preparation technology, and relates to the technical field of chemical engineering. The preparation technology includes two technological processes of raw material preparation and extrusion forming; in the preparation method, sugar cane, straw and other raw materials with short growth cycle and high production rate are chosen as raw materials for production of coated paper and replace wood with long growth cycle and high cost, and the method is a sustainable development means; secondly, the sugar cane, the straw and the like are all green plants growing in nature, a virgin pulp is used for preparation of the coated paper used for package paper or meal box paper and the like so as to be more environmentally friendly and hygienic, the content of harmful heavy metals is far lower than that of ordinary coated paper, and the coated paper is nonpoisonous and harmless; thirdly, reutilization of the straw also avoids environmental pollution brought by straw burning and is a way of turning waste to treasure, and in the process of degradation, a natural world microbial population can play a role of biodegradation to fully degrade the coated paper with the raw materials; and finally, the time required for discoloring of the coated paper is long, and thus the hygienic performance is good.
Description
Technical field
The present invention relates to chemical technology field, be specifically related to a kind of preparation technology of environment-friendly type leaching membrane paper.
Background technology
Along with the development of modern science and technology, the rhythm of life of people is accelerated, and disposable daily necessities miscellaneous such as the fast food outer packaging such as dixie cup and hamburger etc. enters into daily life, and leaching membrane paper is namely make the necessary material of these products.Leaching membrane paper is owing to being applied to the industries such as food, so its security and health are the aspects that we must consider, secondly, find the material that other production cost is low, avoid using timber to be also the problem needing solution badly to the destruction of forest environment in a large number, and improve disposable product degradable degree and shorten degradation time, problems such as " white pollutions " that prevent petroleum base polymkeric substance from bringing all needs to take into account.Along with people are to the more and more concern of health, to the more and more attention of environment, the requirement of people to leaching membrane paper is more and more higher, such as environment protection health, and color and luster is normal, free from extraneous odour, foreign matter, without chemical and toxicological harmless etc.But, the leaching membrane paper of current use is raw material mainly with timber greatly, a large amount of use timber, brings immense pressure to ecology and more use petroleum base polymkeric substance is unfavorable for welding of degrading, and has news report to say, the bubble face box that some traditional leaching membrane papers are made in use, have as objectionable impurities as wax etc. oozes out, human body cannot digest after taking in and mediate, and accumulates over a long period, be blocked in enteron aisle inside, cause foul disease.Therefore, develop a kind of energy-saving environment protection health, the leaching membrane paper preparation technology meeting the strategy of sustainable development becomes trend of the times to replace common leaching membrane paper to produce.
Summary of the invention
It is simple that problem to be solved by this invention is to provide a kind of production technique, and lens materials safety is comfortable, the preparation method of the high-hydrophilic Tinted contact lenses material that colour fastness is high.
To achieve these goals, the technical scheme that the present invention takes for: the preparation technology of a kind of environment-friendly type leaching membrane paper provided, comprises following processing step:

(2) extrusion moulding: raw material obtained in step (1) is mixed with the auxiliary material prepared in advance, make membrane coating material, in twin screw extruder, carry out frit reaction can obtain leaching membrane paper, twin screw extruder comprises intake zone, Screw Extrusion district, filtration zone and die head district, intake zone temperature is 90 ~ 100 DEG C, Screw Extrusion district temperature is 260 ~ 380 DEG C, and die head district temperature is 240 ~ 360 DEG C.
Preferably, the granulation diameter pulverizing granulation in pulverizer described in described step (1) is 0.4 ~ 0.6mm.
Preferably, in described step (1), the composition of degradable resin used is the mixture of poly(lactic acid) and polyhydroxyalkanoate.
Preferably, in described step (2), auxiliary material used comprises organosilicon and anti-aging agent.
Preferably, described anti-aging agent is 2,6 di tert butyl 4 methyl phenol.
Preferably, in described auxiliary material, the massfraction of organosilicon and anti-aging agent is respectively 60 ~ 65% and 35 ~ 40%.
Preferably, the mixing of described step (2) Raw and auxiliary material is the mixing using high-speed mixer to carry out material, and the rotating speed of high-speed mixer is 30000 ~ 35000r/min.
Adopt technical scheme of the present invention, by selecting the growth cycle such as sugarcane and stalk short in this process of preparing, the high raw material of productive rate is as the starting material producing leaching membrane paper, instead of the long and timber that cost is high of growth cycle, a kind of means of Sustainable development, secondly, sugarcane and stalk etc. are the green plants of nature growth, its magma is used for making leaching membrane paper for the more environmentally-friendly sanitary such as wrapping paper or cutlery box paper, harmful heavy metal content is far below common leaching membrane paper, nontoxic, again, the recycling of stalk also avoid the environmental pollution that straw burning brings, a kind ofly give up as the approach of treasured, in degradation process, natural microbial population can play biological degradation, abundant degraded this kind of raw material leaching membrane paper, finally, it is long that the present embodiment drenches unconcerned paper decolouring required time, sanitation performance is good.
