A kind of bio-based composite material hose and production method thereof |
| abstract |
The invention discloses a bio-based composite material hose and a preparation method thereof, belonging to the field of bio-based composite materials. The hose comprises an inner rubber layer, an outer rubber layer and a strip reinforcement layer. The inner rubber layer and the outer rubber layer It is a bio-based water-based polyurethane material, the belt blank reinforcement layer is woven from polylactic acid fibers, and the strip blank reinforcement layer is arranged between the inner rubber layer and the outer rubber layer; the production method includes the following steps to prepare the bio-based water-based polyurethane Materials; use a circular loom to weave polylactic acid fibers into a belt blank; use a coating machine to uniformly coat the above bio-based aqueous polyurethane dispersion on the inner and outer surfaces of the belt blank, dry at room temperature, and then enter a drying tunnel at 60°C After curing for more than 12 hours, a coated film is formed inside and outside the tape blank, and a bio-based composite material hose is obtained. The beneficial effects of the invention are as follows: the properties such as elongation at break and tensile strength of the castor oil-based water-based polyurethane can be significantly increased, and the prepared bio-based water-based polyurethane film has excellent mechanical properties. |
