Embodiment Construction

[0014] Example group 1

[0015] The composition of the test formulations is shown in Table 1. Wherein, the consumption of epoxy succinate and diethyl epoxy succinate is 0.5 parts by weight added to 100 parts by weight of PVC resin.

[0016] Table 1

[0017]

[0018] Put the above mixture on a two-roller plasticizing machine with a roller temperature of 150°C and a roller distance of 1 mm for 3 minutes. After taking the piece, cut it into a 2 cm×2 cm square test piece. According to the requirements of the GB / T 7141-92 standard, the The PVC sheets are grouped in order and placed in the aging oven, and the oven aging test is carried out at 180±1°C. The test pieces are taken out every 10 minutes, and the changes in the color of the test pieces are observed and recorded. The time continues until the test pieces appear black. , the results are shown in Table 2.

Abstract

Use of epoxy succinate and / or diethyl epoxy succinate as heat stabilizer for PVC, containing at least one epoxy succinate and / or diethyl epoxy succinate, epoxy succinate and / Or the consumption of diethyl epoxysuccinate is to add 0.1~5 parts by weight in 100 parts by weight of PVC; wherein, the epoxysuccinate is zinc epoxysuccinate, calcium epoxysuccinate, epoxysuccinic acid One or more of fatty amine salts and cycloaliphatic amine salts of epoxysuccinic acid. Epoxy succinate and / or diethyl epoxy succinate are non-toxic, environmentally friendly, and have a large epoxy group content, which can improve the initial whiteness and long-term thermal stability of PVC, and the thermal stability effect is obvious. The raw material is easy to obtain, the preparation is convenient, etc.; the industrial application prospect is broad.

Description

technical field [0001] The present invention relates to epoxy succinate and / or the new purposes of epoxy succinate diethyl, more specifically, the present invention relates to epoxy succinate and / or epoxy succinate diethyl as PVC thermal stabilizer Applications. Background technique [0002] Epoxy auxiliary heat stabilizers can achieve good synergistic performance in low-lead or lead-free additive systems. For example: Compared with phosphite, epoxidized soybean oil can endow polyvinyl chloride (PVC) products with good long-term thermal stability in lead-free and tin-free formulations (Jiang Yiwen, Zhao Liangliang, Cao Changqing, Plastic Industry, 2009, 37(2 ):47~49,70). So far, epoxy heat stabilizers have been reported one after another: epoxy rapeseed oil (Cheng Daoyu, Wang Jinliang, Fu Changchun, Yu Yuying, Henan Science, 1989, (No. 3~4), 64~69); epoxy sunflower oil Oil (Huo Hong, Wei Zhixian, Shanxi Chemical Industry, 1998, (2): 58~59), etc. Due to the different epox...
