Description
Technical Field
The invention relates to the technical field of flame-retardant ABS additives and preparation methods thereof, in particular to a stabilizer for chlorinated polyethylene used for flame-retardant ABS production and a preparation method thereof.
Background
Chlorinated Polyethylene (CPE) is a random polymer made from powdered High Density Polyethylene (HDPE) specialty by suspension chlorination with aqueous or hydrochloric acid phase. Chlorinated Polyethylene (CPE) is used as a saturated high polymer material, is nontoxic and odorless, has excellent weather resistance, ozone resistance, chemical resistance and ageing resistance, and has good oil resistance, flame retardance and coloring performance, and good toughness (the CPE has flexibility at-30 ℃). The chlorinated polyethylene resin has wide application, is not only an excellent impact modifier for PVC plastics, but also an elastomer material with good comprehensive performance, has been widely used for products such as wires and cables, rubber tubes, waterproof coiled materials and the like, and has good development prospect.
ABS plastic is a terpolymer of acrylonitrile (A) -butadiene (B) -styrene (S). ABS plastic is widely applied in manufacturing industries such as machinery, electricity, textile, automobiles, airplanes, ships and the like and chemical industry. With the increasingly strict requirements on the flame retardant performance of various equipment parts such as household appliances, communication and the like, the demand of flame retardant ABS plastic is rapidly increased. However, ABS itself has poor flame retardancy, and flame retardant is added to improve flame retardant effect in practical application, and the addition of flame retardant reduces physical properties of ABS, especially impact properties of products. In order to ensure that the ABS plastic has good flame retardant property and still can keep good mechanical property and molding processability, a third component, namely a thermoplastic elastomer with polar groups, is often added into the ABS resin and brominated flame retardant formula system. The Chlorinated Polyethylene (CPE) has good performance in the aspect of impact modification of products, and meanwhile, the CPE contains chlorine element, so that the flame retardant has good flame retardant property and has the characteristic of flame dripping prevention, and the flame retardant is matched and cooperated with a brominated flame retardant, antimony oxide and other proper proportions to be applied to ABS, so that the flame retardant is an ABS flame retardant material with excellent flame retardant property and low cost.
The melting temperature of ABS plastic is 217-237 deg.C, the thermal decomposition temperature is above 250 deg.C, and the forming temperature is 200-240 deg.C. And the thermal stability time measured by the Congo red method of chlorinated polyethylene: dehydrochlorination decomposition and yellowing problems occur at high temperatures exceeding 200 ℃ for about 12min at 165 ℃. Therefore, when the chlorinated polyethylene is used for flame-retardant ABS, calcium stearate, a calcium zinc stabilizer, an organic tin stabilizer and the like are required to be added to improve the heat stability of CPE, so that the stability and whiteness of the flame-retardant ABS are improved. However, due to the defects of the calcium carbonate and the zinc carbonate, the whiteness of the calcium carbonate is poor at high temperature, the common calcium zinc stabilizer is insufficient in heat resistance, changes color for a long time, the organic tin stabilizer is peculiar smell and the like, and the flame-retardant ABS plastic molded product often has the problems of color difference, yellowing, black macula and the like, and seriously influences the product quality.
