Embodiment 1
[0027] Embodiment 1, the polybutylene succinate degradable film composite material contains 50 parts to 90 parts of polybutylene succinate, polybutylene adipate-terephthalate 10-50 parts of alcohol ester, 10-50 parts of filler, 5-25 parts of lubricant.
Embodiment 2
[0028] Example 2, the polybutylene succinate degradable film composite material contains 50 parts or 90 parts of polybutylene succinate, polybutylene adipate-terephthalate 10 or 50 parts of alcohol ester, 10 or 50 parts of filler, 5 or 25 parts of lubricant.
Embodiment 3
[0029] Embodiment 3, as the optimization of above-mentioned embodiment: the filler of embodiment 3 is micron grade calcium carbonate or cornstarch. Calcium carbonate is the most widely used and most used inorganic mineral powder material. It has many advantages such as abundant sources, low price, easy processing, and non-toxicity. Starch is a renewable, cheap, widely sourced, and biodegradable natural polymer material. Adding starch to biodegradable polymers not only reduces the cost, but also meets the requirements of environmental protection.

Abstract
The invention relates to the technical field of composite materials for a film, and provides a composite material for a poly(butylene succinate) degradable film and a preparation method thereof. The composite material for a poly(butylene succinate) degradable film comprises the following components in parts by weight: 50-90 parts of poly(butylene succinate), 10-50 parts of poly(butylene adipate-terephthalate), 10-50 parts of filler and 5-25 parts of lubricant. The preparation method comprises the following steps: mixing dried poly(butylene succinate), dried poly(butylene adipate-terephthalate), filler and lubricant; performing melt blending through a double screw extruder; and granulating. The prepared composite material for a poly(butylene succinate) degradable film has the characteristics of simple preparation process, low raw material cost, excellent mechanical property and biodegradability; the production cost is lowered; and the environmental requirements are met.
Description
technical field [0001] The invention relates to the technical field of composite materials for films, and relates to a composite material for polybutylene succinate degradable films and a preparation method thereof. Background technique [0002] As a widely used product, polymer films are often used as semiconductor materials, electrical materials, isolation materials, etc., especially in agriculture and packaging industries. Commonly used polymer film materials include PVC, LDPE, HDPE, metallocene PE, PP, PS, EVA, PET, PA, PC, EVOH, F4, and PI. A disadvantage of these materials is that they are not fully biodegradable, so they will cause environmental pollution problems during use, that is, "white pollution"; at the same time, the production costs of these materials are high and they are heavily dependent on petroleum. Contents of the invention [0003] The invention provides a composite material for a polybutylene succinate degradable film and a preparation method there...
