Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples.
As shown in fig. 1 and fig. 2, the embodiment of the invention discloses a method for producing stone paper by using stone paper scraps, which comprises the steps of crushing the stone paper scraps, regenerating and granulating to obtain a regenerated material; and mixing the reclaimed material with polyethylene, adding the mixture into a film blowing paper machine, and performing blow molding to obtain the reclaimed stone paper. Preferably, the stone paper leftover bits are broken into 0.5-1cm fragments. The thickness of the stone paper leftover material is more than 200 microns. The thickness of the regenerated stone paper is 30-80 microns.
The embodiment obtains new regeneration stone paper through mixing the blowing behind the granulation with the regeneration of stone paper leftover bits with polyethylene, has realized the reutilization of stone paper.
In some preferred embodiments of the present invention, based on the above embodiments, the drawing speed of the blown film paper machine is 23-35m/min, preferably 30.3m/min, and further, by accurately adjusting the drawing speed of the blown film paper machine, it is ensured that the regenerated stone paper cannot be obtained due to too short molecular chains. Too high drawing speed may cause paper breakage, and too low drawing speed may cause excessive product thickness.
In some preferred embodiments of the present invention, based on the above embodiments, the mass ratio of the reclaimed material to the polyethylene is (75-95): (5-25). The raw material proportion can not only ensure the effective utilization of the leftover materials of the stone paper, but also ensure the quality of the regenerated stone paper. The proportion is too big, can increase the paper density grammes per square metre and exceed standard, and the polyethylene addition increase can cause manufacturing cost to rise, and the proportion undersize can cause product thickness not up to standard, the condition of paper fracture even appears.
In some preferred embodiments of the present invention, the granulation temperature of the regeneration granulation is 160-180 ℃ based on the above embodiments. By adopting the temperature granulation, the regenerated paper particles can be fully melted, and the density of the regenerated particles is ensured to be uniform; impurities contained in the leftover materials are separated out and filtered at a filter screen. If the temperature is too low, the fluidity of the material is poor, and the machine equipment is easy to block; if the temperature is too high, scorching of the material may be caused.
In some preferred embodiments of the present invention, based on the above embodiments, the blow temperature of the blown film paper machine is 160-170 ℃. The recycled paper particles and the polyethylene can be fully melted, flowed and combined together, and the thickness of the product is ensured to be uniform; impurities contained in the regenerated particles are separated out and filtered at a filter screen. The temperature is too high, the resin is easy to decompose, the film is brittle, and particularly the longitudinal tensile strength is obviously reduced; at low temperatures, the resin plasticizes poorly and has poor surface gloss and clarity, even with the presence of unmelted PE particles.
The embodiment of the invention also discloses regenerated stone paper with the thickness of 30-80 microns and the density of 0.8-1g/cm3The gram weight is 24-80g, and the water vapor transmission capacity is 12-35 (g/cm)224h) tear strength from 2 to 5.5N. Can be prepared by the method.
