Problems solved by technology

At present, these nucleating agents also have the problem of poor compatibility with PCL, and are prone to agglomeration. When the amount added is high, it will affect the mechanical properties of the product and the appearance of the product.
The mechanical properties of PBAT and PBSA are similar to those of PCL, with higher elongation at break, but lower strength, faster degradation rate, and poorer crystallization properties

Embodiment 1

[0072] First dry polybutylene succinate 50g, N 1 ,N 1' -Ethyl-bis-N 2 0.4g of -phenyl bisoxamide, 0.3g of epoxidized soybean oil, 0.2g of 1,1,3-tris(2-methyl-4-hydroxy-5-tert-butylphenyl)butane and mix well at room temperature The premix was obtained, and then the above premix was melt-blended with an internal mixer at 130° C. for 5 minutes, and the rotor speed of the internal mixer was 50 rpm to obtain a polybutylene succinate material composition.

Embodiment 2

[0074] First dry polybutylene succinate 50g, N 1 ,N 1' -Ethyl-bis-N 2 - 0.5 g of phenyl bisoxamide was uniformly mixed at room temperature to obtain a premix, and then the above premix was melt blended at 130° C. for 5 minutes with an internal mixer, and the rotor speed of the internal mixer was 50 rpm to obtain a polybutylene Butylene glycol diacid material composition.

Embodiment 3

[0076] First dry polybutylene succinate 50g, N 1 ,N 1' -Ethyl-bis-N 2 -Phenyl bisoxamide 0.75g, Mix 0.2g of ADR43000, 0.2g of stearyl propionate, and 1g of talc powder at room temperature to obtain a premix, and then use an internal mixer to melt and blend the above premix for 5 minutes at 130°C. At 50 rpm, a polybutylene succinate material composition was obtained.

Abstract

The invention discloses a bio-compostable polyester material composition, which is mainly composed of the following components in parts by weight: 100 parts of bio-compostable polyester and 0.05 to 5 parts of organic modifier; wherein the chemical formula of the organic modifier is R1-NH-C(O)-C(O)-NH-R2 or R1-NH-C(O)-C(O)-NH-R0-NH-C(O)-C(O)-NH-R2, and the R0, R1 and R2 individually represent an alkyl group or an alkyl group containing a substituent. The bio-compostable polyester material composition prepared by the provided preparation method has the characteristics of high crystallization temperature, fast crystallization speed, short semi-crystallization period, and high mechanical strength, and can shorten the forming period, reduce the cost, and improve the performance. Moreover, the preparation method has the advantages of simpleness, environment-friendliness, and easiness for industrialization.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an organic modifier for biocompostable polyester materials, a composition and a preparation method thereof. Background technique [0002] With the increasing shortage of energy and the deterioration of the environment, biocompostable polyester materials have gradually been favored by people. The so-called biocompostable material means that it should be biodegradable within 180 days in an industrialized composting environment (60°C, with microorganisms present), and the compostable material will not leave fragments in the residue that have existed for longer than about 12 weeks. Heavy metals or toxic substances, and can sustain plant life. Currently commercialized biocompostable polyester materials mainly include polylactic acid (PLA), polyhydroxyalkanoate (PHA), polybutylene succinate (PBS), polycaprolactone (PCL), polycaprolactone Diacid / butylene terephthalate (PBAT)...
