Abstract
The invention discloses a white master batch specially used for milk membrane and a preparation method therof. The white master batch comprises 50 per cent to 85 per cent of titanium pigment, 1 per cent to 10 per cent of disperse lubricants, 5 per cent to 15 per cent of carrier resins, 2 per cent to 4 per cent of antibacterial agents and 2 per cent to 3 per cent of modifiers in weight percentage. Compared with the prior art, the invention has the advantages of small addition amount, easy dispersion, high white content, bacterial resistance, and strong hiding power, etc., has no effect on the mechanical performance and printing performance of the products, has degradation performance and can be widely suitable for the pigmentation of the polythylene milk membrane.
Description
Technical field
The present invention relates to a kind of special while master batch for milk membrane and preparation method thereof, belong to the coloring plastic technical field.
Background technology
Raising along with expanding economy and people's living standard, the dairy industry of China has obtained developing rapidly and growing in strength, great change has also taken place in people's mode of life and diet formula, milk has become the necessary article on the ordinary people dining table, bottled milk, because it is weight is big, easily broken, be eliminated gradually, and adopt the milk of plastics film soft packaging to occupy sizable ratio.At present there is following shortcoming in the white master material on the milk film market: 1, titanium dioxide content is low, thus during blown film addition up to 30%, the cost height; 2, contain lubricant, slipping agent is many, because film surface needs printing, influences the printing of film; 3, all be non-biodegradable material, be unfavorable for environmental protection and Sustainable development; 4, do not contain degradative plastics, be unfavorable for environmental protection; 5, there is not antibiotic performance.
Summary of the invention
In order to overcome the deficiency that present milk film white master batch exists, the purpose of this invention is to provide a kind of have the concentration height, easily dispersion, degradable, addition is few and add after do not influence special while master batch for milk membrane of film printing and preparation method thereof.Realize that the technical scheme that the object of the invention adopted is:
The weight percent of this each component of master batch is: titanium dioxide 50-85%, dispersed lubricant 1-10%, vector resin 5-15%, antiseptic-germicide 2-4%, properties-correcting agent 2-3%.
Titanium dioxide is one or more of anatase thpe white powder or rutile titanium white powder.
Dispersed lubricant is one or more of boric acid ester coupler, hyper-dispersant, polyethylene wax.
Vector resin is one or more of ethylene acrylic acid co polymer (be called for short EAA) plastics, metallocene linear-low density polyethylene, new LDPE (film grade).
The method for preparing this master batch is: earlier each compositions in weight percentage is carried out pre-mixing, be to mediate 15-60 minute in the high speed kneader of 800-1500/min at rotating speed then, the compound that to fully mediate at last adds in the parallel double-screw extruder to be extruded, and cuts the back and packs and make required master batch through die face is fervent, air-cooled.
The present invention compared with prior art has advantages such as few, the easy dispersion of addition, whiteness height, antibiotic, strong covering power, does not influence the mechanical property and the printing performance of goods, has degradation property, can be widely used in the painted of polyethylene milk film.
