Abstract
A cellulose fiber composite resin composition including: a base resin; a cellulose fiber; a low molecular weight resin; and a crosslinking agent capable of forming a crosslinked structure in at least two of: “within the base resin”, “within the low molecular weight resin”, and “between the base resin and the low molecular weight resin”.
Claims19
A cellulose fiber composite resin composition comprising:
- a base resin;
- a cellulose fiber;
- a low molecular weight resin;
- and
- a crosslinking agent capable of forming a crosslinked structure in at least two of:
- “within the base resin”, “within the low molecular weight resin”, and “between the base resin and the low molecular weight resin”.
A method for producing a cellulose fiber composite resin composition, the method comprising:
- a mixing step of adhering a low molecular weight resin having a lower molecular weight than a base resin and having a powdery form or a liquid form to a cellulose fiber;
- and
- a step of kneading the base resin;
- the cellulose fiber;
- the low molecular weight resin;
- and a crosslinking agent capable of forming a crosslinked structure in at least two of:
- “within the base resin”, “within the low molecular weight resin”, and “between the base resin and the low molecular weight resin” to form a cellulose fiber composite resin composition.
A cellulose fiber composite resin molded object made from a cellulose fiber composite resin composition containing a base resin;
- a cellulose fiber;
- a low molecular weight resin;
- and a crosslinking agent, wherein
- the molded object has a crosslinked structure through the crosslinking agent in at least two of:
- “within the base resin”, “within the low molecular weight resin”, and “between the base resin and the low molecular weight resin”.
A method for producing a cellulose fiber composite resin molded object, the method comprising:
- a step of kneading a base resin;
- a cellulose fiber;
- a low molecular weight resin;
- and a crosslinking agent to obtain a cellulose fiber composite resin composition;
- a step of molding the cellulose fiber composite resin composition to obtain a molded object;
- and
- a step of exposing the molded object to radiation to form a crosslinked structure through the crosslinking agent in at least two of:
- “within the base resin”, “within the low molecular weight resin”, and “between the base resin and the low molecular weight resin”.
