Abstract

The invention discloses zeolite 4A, a preparation method and device and application of zeolite 4A, PVC and a preparation method of PVC, and belongs to the technical field of zeolite 4A. The preparation method of zeolite 4A includes the steps that a sodium aluminate solution with first set parameters, a sodium silicate solution with second set parameters and a soluble calcium salt solution with third set parameters are mixed to obtain slurry containing Ca2+; the slurry containing Ca2+ is subjected to synthesis under set conditions to obtain a synthetic product; the synthetic product is crystallized under set crystallization conditions to obtain a crystallized product; the crystallized product is subjected to separation, washing and drying in sequence to obtain zeolite 4A. The device comprises a first vessel, a second vessel, a third vessel, a slurry formation tank, a crystallization tank and a drying device. In zeolite 4A, based on CaO and Al2O3, the value range of the amount-of-substance ratio of CaO to Al2O3 is 0.01-0.05. By applying zeolite 4A prepared through the preparation method and device to the PVC preparation process as a heat stabilizer, the heat stability of obtained PVC is improved.

Description

technical field [0001] The invention relates to the technical field of 4A zeolite, in particular to a 4A zeolite, its preparation method, preparation device, application, PVC and its preparation method. Background technique [0002] Polyvinyl chloride, referred to as PVC (Polyvinyl chloride), is a vinyl chloride monomer (vinyl chloridemonomer, referred to as VCM) in peroxides, azo compounds and other initiators; or under the action of light and heat, it can be polymerized according to the mechanism of free radical polymerization. made polymer. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. PVC is a white powder with an amorphous structure. It has poor stability to light and heat. It will decompose and produce hydrogen chloride when it is above 100°C or exposed to sunlight for a long time, and further autocatalytic decomposition will cause discoloration and rapid physical and mechanical properties. In practic...
