Embodiment 1

[0049] The ratio of cyanuric acid, zinc oxide and uracil were obtained in the proportion of the substance of 6: 9: 1, and the spherium used was 30: 1. First, the cyanic acid is placed in a ball mill in a ball mill, and a small amount of epoxy soybean oil is added, and the adjustment ball mill is 300 r / min, and then zinc cyanic acid is obtained. Then, the uracil is added to the ball mill, and continue to ground 4h, result The cyanuric acid-uracididia zinc salt; finally heated the ball mill to dry the synthetic acid-uracididin zinc salt and add an appropriate amount of dispersant to obtain a product.

Embodiment 2

[0051] Zinc oxide, cyanuric acid, and uracil were referred to by mass of 8: 6: 1, and the spherium used was 30: 1. First, the cyanic acid is placed in a ball mill in a ball mill, and a small amount of epoxy soybean oil is added, and the ball mill is adjusted to 300 r / min, and the zinc cyanic acid is obtained. Then, add 6-amino-1, 3-3- Dimethyluronyrimidine, continuously ground 4 h, resulting in a cyanuric acid-uracil zinc salt; finally heating the ball mill drying the synthesized cyanic acid-uracididin zinc salt and adds an appropriate amount of dispersing agent to obtain a product.

[0052] The zinc salt sample prepared by the second embodiment and the proportion of zinc oxide: cyanurate: cyanurate: cyanurate: uracil mass ratio = 8: 6: 1 is compared , The resulting infrared comparison map figure 2 Indicated. like figure 2 As shown, the above spectrum is an infrared spectrum of the sample of this Example 2, and the following map is a sample infrared spectrum after mixing. From f...

Abstract

The invention provides a method for solid-phase synthesis of cyanuric acid-uracil complex zinc salt, which comprises the steps of: mixing cyanuric acid and zinc oxide under shearing conditions, and reacting to obtain zinc cyanurate; The zinc cyanurate is mixed with uracil and reacted to prepare cyanuric acid-uracil complex zinc salt. The present invention reacts by adopting a dry grinding method, and the reactants are dry-milled in equipment with high shear force and high contact area to obtain cyanuric acid-uracil complex zinc salt, and the prepared cyanuric acid-uracil complex The particle size of the zinc salt is small, and the particle size distribution is uniform at the same time, which will not affect the subsequent processing of PVC; the trace water generated during the reaction can be simply removed by heating the equipment, the preparation process is simple, and the energy consumption is small; The solvent disperses the reactants. After the reaction is completed, there is no solvent to be disposed of, no waste water discharge, and it is clean and environmentally friendly.

Description

Technical field [0001] The present invention relates to cyanurate - Preparation art uracil complexed zinc salts, more particularly to a solid phase synthesis cyanurate - Method uracil complexed zinc salt. Background technique [0002] Polyvinylchloride (PVC) and polyethylene, polypropylene, polystyrene, ABS and thermoplastic synthetic resin and said five. In several general synthetic resins, PVC polyethylene production just below, in second place. PVC has excellent chemical resistance, electrical insulation, flame resistance and mechanical properties, and combines the advantages of light weight, high strength, low cost, is widely used in various fields of industry, agriculture, construction, electrical and electronic daily necessities . [0003] Due to the unstable structure of PVC molecular chain, the thermal processing temperature of the PVC decomposition temperature close to readily produce HCl removed degradation, resulting in decreased performance and discoloration, and ther...
