[0047] The preparation method of described cyclodextrin / polyethylene glycol complex is as follows:

[0048] Dissolve a certain amount of cyclodextrin in water at 60°C to obtain a saturated aqueous solution of cyclodextrin, and add a certain amount to the saturated aqueous solution of cyclodextrin according to the molar ratio of cyclodextrin to polyethylene glycol Polyethylene glycol, and mechanically stirred for 1h, at room temperature, stood still for 24h, a precipitate appeared. The precipitate was vacuum-filtered, washed, and vacuum-dried at 30°C until constant weight. The molar ratio of cyclodextrin to polyethylene glycol is 1:1.

[0049] The applicant found that adding the cyclodextrin / polyethylene glycol compound can not only play a plasticizing role, but also increase its high temperature resistance, and it will not damage its structure even if it is soaked in hot water for a long time.

[0050] The antioxidant may include: at least one of phenolic antioxidants, phosp...

Abstract

The invention relates to the field of biological materials, and in particular to a bio-based composite material as well as a preparation method and application thereof. The bio-based composite material is at least prepared from the following raw materials in parts by weight: 100 parts of a carrier resin, 1-30 parts of starch and 1-80 parts of cellulose. The preparation method of the bio-based composite material at least comprises the following steps: mixing the raw materials in a high-speed mixing machine, and stirring for 30-60 minutes at 30 DEG C. The bio-based composite material can be applied to fields such as plastic, buildings, homes, traffic facilities and public facilities.

Description

technical field [0001] The invention relates to the field of biomaterials, in particular to bio-based composite materials and their preparation methods and applications. Background technique [0002] Since the 20th century, plastic materials have developed rapidly at a high speed, and its raw material base is based on abundant petrochemical products, but petroleum is a non-renewable resource, and its reserves are limited, which forces people to Need to pay attention to the development and utilization of renewable resources. According to the forecast of the U.S. Information and Energy Administration, by 2025, the reserves of world oil resources (including unproved reserves) will be 2946.8 billion barrels. If the world's oil consumption in 2003 was 80 million barrels per day, and it is estimated that the consumption will increase to 118 million barrels per day in 2030, the currently proven oil resources can only be used for another 30 years. [0003] Furthermore, due to the ...
