Summary of the invention
The present invention proposes a kind of modified paraffin, have steady quality, produce simple, cost is low, the advantage of paper tube qualification rate high (not alice).
Technical scheme of the present invention is: a kind of modified paraffin, mixed by following raw materials according, and raw materials by weight is: compound wax is 90-94%, and polyethylene is 2-4%, and Atactic Polypropelene is 1-2%, and rosin is 3-4%.
In the technique scheme, raw materials used have a following characteristics:
(1), compound wax: be the byproduct of petrochemical complex, fusing point is low, cheap (cost is low), be easy to get and environmental protection;
(2), polyethylene: be high molecule plastic, molecular structure is regular, and his softening temperature is high, and matter is hard.Though his add-on is little, can improve greatly fusing point and the penetration degree of compound wax;
(3), Atactic Polypropelene: be high molecule plastic, molecular structure irregularity, his softening temperature height.Though his add-on is little, can improve compound wax and poly consistency, improve fusing point and the penetration degree of compound wax;
(4), rosin: be polar material, his adding can make the polyethylene and Atactic Polypropelene and compound wax can be well compatible, and the viscosity because of rosin reduces the alice of paper tube greatly simultaneously, thereby has improved qualification rate.
Beneficial effect: a kind of modified paraffin of the present invention not only has steady quality, production is simple, cost is low, the advantage of paper tube qualification rate high (not alice), and the modified paraffin proportioning with above-mentioned raw material production can be adjusted with user's needs, production safety, simple, cost is low.
Embodiment
Embodiment 1:
A kind of modified paraffin, it is prepared as follows: by weight percentage, get 4% polyethylene, 2% Atactic Polypropelene and 3% rosin, by forcing machine (temperature is controlled at 150-200 ℃), get mixture after simple the mixing; Mixture with 9% and 91% compound wax melt compounding stir, and product is put into iron pan while hot, naturally cool to room temperature again, pound into fritter with hammer, and packing after the splitting metering gets finished product.
Embodiment 2:
A kind of modified paraffin, it is prepared as follows: by weight percentage, get 2% polyethylene, 3% Atactic Polypropelene and 5% rosin, by forcing machine (temperature is controlled at 150-200 ℃), get mixture after simple the mixing; Mixture with 10% and 90% compound wax melt compounding stir, and can be directly used in pipe crimping (explosive paper tube).
The main quality index of a kind of modified paraffin of the present invention is as follows:
1., outward appearance: white waxy solid, the visible mechanical impurity of nothing;
2., fusing point: 〉=60 ℃;
3., penetration degree 1/10mm (25 ℃, 100g): 〉=22.
The storage of a kind of modified paraffin of the present invention: deposit in shady and cool dry ventilation, temperature should not be above 45 ℃.Validity period is 2 years.
