White PVC granulation formula due to the degradation of PVC products in the process of large, high temperature, the degradation is more serious, therefore, the general regeneration of PVC in the granulation are to add some heat stabilizer, which can greatly improve the means of regeneration of particles.
(1) the formula for the sole:
Formulation 1: waste soft mass of 100 kg
Flame retardant agent, colorant, 2 kg
Petroleum ester 15 kg
(such as: three, two, second tier oil line oil ester etc.)
Barium stearate 1 kg
Carbon black 0.1 kg
Formula 2: waste sole material (refers to PVC soles) 100 kg
6 fat two kg
Barium stearate 1 kg
Hard calcium carbonate 1.5 kg
Chlorinated paraffin 1 kg
The function and symbol of the additive:
Flame retardant agent, colorant, three iron chloride two: Fe2o3
Barium stearate, calcium stearate, zinc, calcium, etc., are commonly used as metal soap stabilizers, lubricants:
Barium Titanate: BaSt
Hard acid cadmium: CdSt
Zinc acetate: ZnSt
Calcium stearate: CaSt
Chlorinated paraffin: commonly used chlorine content of 42% and 52%, has the advantages of low volatility, non flammability, low price, plasticization, also is to raise the technical index of plastics.
PCL (Paraffin) - 50 (the number of chlorine content): refers to the chlorine content of 50% chlorinated paraffin.
Waste polyvinyl chloride film material
Formula: waste PVC membrane material 100 kg
Plasticizer (two -) 5-15 kg
(such as: dioctyl, plant ester, such cost is high, may also use a second tier oil and three oil and low cost of oil ester according to the actual situation)
Stabilizer (three salt) of about 3 kg
(such as: three salt, two salt, hard ester acid barium, cadmium, zinc, calcium and other can be used, can also be used alone)
Lubricant (hard ester acid barium) 1 kg
(such as: chlorinated paraffin or hard ester acid, barium, calcium, zinc, calcium, etc.)
Description: stabilizer and lubricant can not be used at the same time, it is said that, if the hard ester acid barium as stabilizer, the lubricant should be chlorinated paraffin or paraffin. If you want to change the performance of its plastic, it can also be used to improve the performance of the plastic:
Waste: 100 kg, 2 kg into two ester can improve its softness.
