6, compound wax refers to by different boiling range slack waxs and helps various compositions such as emulsion, thickening material to be composited, the melt viscosity height, and good dispersity, high lubricating effect, chemical-resistant resistance is strong, and electrical property is excellent, and the normal temperature humidity-proof ability is strong.
7, thinner alpha-methyl styrene, thinner are the liquid substance of class when liquid resin viscosity is weakened.It can not dissolving resin, but can partly replace solvent.The effect of thinner is to reduce resin viscosity, makes resin have flowability, improves the wetting property of resin to strongthener, filler etc.; Reaction heat when control is solidified; Prolong the working life of resin solidification system; Amount of filler increases, and reduces cost.
8, auxiliary agent poly alpha methylstyrene, its structural formula is as follows:
Compound wax among the present invention is by different boiling range slack waxs and helps various compositions such as emulsion, thickening material to be composited.Stir by mixing, water-ground limestone is dispersed in the linear low density polyethylene, and mechanical property strengthens.Adopt corrdination type titanate coupling agent (TIO among the present invention
3(OR)
2) and polyethylene wax unite water-ground limestone coated processing, strengthened water-ground limestone uniformly dispersed in master batch, and improved the consistency with linear low density polyethylene.The application of thinner makes the easier compression moulding of master batch.
Environment-friendly type modified master batch among the present invention can be used for blown film, injection moulding, hollow, wire drawing, pouring film, presses the court of a feudal ruler etc., owing to added 2000-3000 order water-ground limestone in a large number, has greatly reduced the cost of finished product; Fill the plastics transparency height of this environment-friendly type modified master batch, the fine and smooth good luster of finished product can keep the part physical and mechanical property of plastic material preferably.This master batch reaches the food grade environmental protection standard, does not contain any heavy metal, easily degraded; The master batch good fluidity that makes is easy to forming process.
The present invention has following advantage compared to existing technology:
One, be mainly reflected in environmental protection, do not have insalubrious material, loading level is bigger generally about 30-40 part than existing.Corrdination type titanate coupling agent (TIO
3(OR)
2) improve resistance to impact shock, improve mechanical property, improve liquidity oilness.
Two, Zinic stearas has lubricant and thermostability preferably.
Three, to have an addition big for the product of its production, under the prerequisite of keeping product quality and glossiness, effectively reduces raw materials cost; The surface luster of plastics is good, reaches ideal effect; Improved the wear-resisting and non-skid property of surface of plastic products; Adopt imported raw material and nano level inorganic materials to get involved, greatly reduce detrimentally affect, and environmental protection is degraded easily the plastic material aging resistance; Reduce the molding shrinkage of plastics, thereby improve dimensional stability; Reduce the combustion heating amount of plastics, thereby reduced secondary pollution;
Four, thinner is selected alpha-methyl styrene for use, other auxiliary agent is poly alpha methylstyrene A-95 (LLDPE processing aid) and the mixing of tritolyl phosphate TCP, alpha-methyl styrene is the good processing aid of polyolefin plastics, can significantly reduce or eliminate the shear-stress in the plastic working process, reduce balancing torque, promote plasticizing capacity, improve flowability and production capacity.Good to the mould filling, improved the apparent property of goods greatly, the high workability of A-95 is particularly suitable for weighting agent good synergistic being arranged not only, and being significantly reduced to this in the high processing formula of filling.
