Problems solved by technology

[0004] The technical problem to be solved in the present invention is to overcome the defects and deficiencies of the poor long-term thermal stability of existing PVC heat stabilizers, and provide a PVC organic composite heat stabilizer, which is based on tetrahydroxyalkyl glycoluril as a stabilizer. The synergistic effect of the composite components effectively improves the thermal stability, inhibits the zinc burning phenomenon of PVC, and provides a new idea for the research and development of PVC thermal stabilizers

Abstract

The invention discloses a PVC (polyvinyl chloride) organic composite heat stabilizer, a PVC product and a preparation method of the PVC product. The PVC organic composite heat stabilizer is prepared from components in parts by mass as follows: 1-5 parts of tetrahydroxyalkyl glycoluril, 1-5 parts of 1,3-dimethyl-6-aminouracil, 0.5-1 part of zinc stearate and 2-2.5 parts of calcium stearate. The PVCorganic composite heat stabilizer is prepared from tetrahydroxyalkyl glycoluril as a main stabilizer by recombination with other synergistic components, stability of the PVC organic composite heat stabilizer is effectively improved, the zinc burning phenomenon of PVC is relieved, and degradation and aging of PVC are improved; 1,3-dimethyl-6-aminouracil in the PVC organic composite heat stabilizerhas capacity of replacing unstable Cl atoms in PVC, and by means of synergy with tetrahydroxyalkyl glycoluril, the chameleon phenomenon of PVC is eliminated or reduced; the heat stabilizer system contains no heavy metal substances and meets the non-toxic and environmental protection concept.

Description

technical field [0001] The invention relates to the technical field of organic composite materials, more specifically, to a PVC organic composite heat stabilizer, PVC products and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is one of the five general-purpose plastics. Due to its excellent comprehensive performance and low price, it has been widely used in various fields, and its consumption is second only to polyethylene. However, the poor thermal stability of polyvinyl chloride makes it necessary to add appropriate heat stabilizers during processing to inhibit the degradation of polyvinyl chloride. Generally speaking, heat stabilizers can be divided into the following categories: lead salts, metal soaps, organotin and rare earth heat stabilizers. However, the common lead salts and organotin heat stabilizers in the market are toxic to a certain extent. Under the theme of global environmental protection, it is an urgent demand in the ...
