Abstract
The invention discloses an organic acid and rare earth composite heat stabilizer for PVC (polyvinyl chloride). The composite heat stabilizer is prepared by chemically synthesizing a heat stabilizer, lanthanum carbonate, nitric acid, zinc stearate, cerium carbonate, a solvent, sodium hydroxide, a composite antioxidant, hexadecanol, glycerin and mineral oil. According to the composite heat stabilizer, synthesized lanthanum stearate is compounded with other heat stabilizers, so that the thermal degradation temperature of PVC can be increased, the thermal stabilization time of PVC can be prolonged, the balance torque of the PVC can be reduced, the PVC processing power can be effectively reduced, and a large amount of effective energy resources are saved.
Description
Technical field
The present invention relates to chemical field, particularly relate to a kind of PVC organic acid rare earth complex heat stabilizer.
Background technology
Polyvinyl chloride has excellent erosion resistance and very high mechanical property, again because of cheap, abundant raw material, manufacturing process is ripe, and its goods are applied to the every field that workers and peasants also produce, but, PVC adds a fatal weakness man-hour, be exactly poor heat stability, therefore, must thermo-stabilizer be added when processing PVC.
The commercial thermo-stabilizer in the whole world has reached hundreds of, and mainly contain the large class of lead salt stabilizer, metallic soap one package stabilizer, organotin stabilizer and rare-earth stabilizer four, thermo-stabilizer mainly divides tin stablizer, lead stabilizer, mixed metal stabilizer etc. at present.Lead salt stabilizer toxicity is comparatively strong, has biological accumulation, and easily produces dust; Containing heavy metal cadmium, barium etc. in metallic soap one package stabilizer, and cadmium, barium have stronger toxicity, and it is produced and causes serious impact to human health and ecotope in offal treatment process; Although organotin stabilizer performance efficiency, pollution hazard is little, expensive, and cost is high.Although rare earth thermal stabilizer stablizer stabilising effect better and have no side effect, if be used alone, can not reach desirable stabilising effect.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of PVC organic acid rare earth complex heat stabilizer, by the stearic acid lanthanum of synthesis and other thermo-stabilizer compounds, all can improve PVC thermal degradation temperature and heat-stable time, can the balancing torque of PVC decline simultaneously, effectively can reduce the power that processing PVC is, save the mass efficient energy.
