Abstract
The invention provides a preparation method for light conversion film master batches and is characterized in that based on weight proportion, 500 to 750 portions of market-sale micron or nano-degree rare-earth light conversion agent powder, and 500 to 1,000 liquid hydrocarbon liquid paraffin or the dissolved mixture of liquid paraffin and chlorinated paraffin are continuously processed for 3 to 4 hours with 800-1,600w of ultrasonic wave under rapid stirring; the processed light conversion agent dispersoid and 500-1,000 films of macromolecular material are made into light conversion master batches through 20-35 min. of kneading, shearing, mixing, refining and granulating technologies. The method of the invention can prepare the light conversion master batches with the content of micron and nano-degree rare earth light conversion agent accounting for 30% of the weight percentage in the maximum, so that the conversion film (containing 0.15-0.35% of light conversion agent) has simple and reliable production process, and can ensure that the formula system does not contain water and no air bubbles exist in the film.
Description
Technical field
The present invention relates to technical field of polymer materials, specifically a kind of light conversion film master batch and preparation method thereof.
Background technology
Utilize micron, nano-scale rare earth light-converting agent to add to and make the existing successful for many years practice of light-converting film in the polymer materials, the field such as greenhouse, booth that is widely used in the gardening gardens, but its production process relative difficult, Technology is had relatively high expectations, rare-earth light conversion agent addition in polymeric membrane is done not high, dispersity is also even inadequately, in the course of processing (rainy season) also easily cause containing bubble in the film, have a strong impact on the quality of light-converting film.Changeing the light master batch is a generally acknowledged solution, but the preparation of master batch is a difficult problem always.
Summary of the invention
The objective of the invention is to overcome the difficulty that prior art exists, the preparation method of the simple and light conversion film master batch that can ensure the quality of products of a kind of production technique is provided.
The present invention adopts the dispersion medium of suitable liquid hydrocarbon as micron, nano-scale rare earth light-converting agent, adopt the ultrasonic wave under stirring that system is handled, make micron, nano-scale rare earth light-converting agent under high density, be dispersed in the liquid hydrocarbon quickly, and moisture-free in the guarantee system, and then it is prepared as through certain processing technique with corresponding macromolecular material changes the light master batch.
Raw material: selecting for use has plasticising, lubrication to film main body macromolecular material, can under this fixed condition, soak into mutually or fused mutually liquid hydrocarbon such as white oil again simultaneously with micron, nano-scale rare earth light-converting agent, as dispersion medium, to guarantee to make the dispersion of high density, the good hydrophobic nature of while gained system tool.
Technology: by ultrasonication under agitation, make micron, nano-scale rare earth light-converting agent evenly and stably be dispersed in the liquid hydrocarbon, then according to the characteristic of polymer body mould material, being prepared into through technological operations such as kneading, shearing, mixing, mixing and granulations changes the light master batch.
Specifically:, continue processing through 800～1600w ultrasonic wave under stirring fast and obtained the light-converting agent dispersion in 3～4 hours with (weight part) 500～750 commercially available microns or nano-scale rare earth light-converting agent powder, 500～1000 liquid hydrocarbon white oils or white oil and chlorinated paraffin immiscible materials; With the light-converting agent dispersion handled well and 500～1000 film macromolecular materials through 25～35 minutes kneading, shearing, mixing, mixingly become to change the light master batch with prepared by granulating process.
Described film macromolecular material is one or more in polyvinyl chloride, new LDPE (film grade), high density polyethylene(HDPE), linear low density of polyethylene, medium-density polyethylene, the chlorinatedpolyethylene etc.
Method of the present invention can prepare and contain micron, the nano-scale rare earth light-converting agent is up to the commentaries on classics light master batch of 30% mass percent, make light-converting film (containing light-converting agent 0.15-0.35%) production technique simple and reliable, and can guarantee moisture-free in the formula system, in the film bubble can not appear.
