The invention belongs to the technical field of asphalt modification, and discloses a preparation method of bio-oil modified asphalt. The preparation method of the bio-oil modified asphalt comprises the following steps: heating the matrix asphalt to a first temperature, then adding the plant-based bio-oil into the matrix asphalt while heating until the matrix asphalt is heated to a second temperature, and then dispersing to obtain the bio-oil modified asphalt.

Provided is a thermostat device with which a flow rate of a cooling liquid from a bypass passage can be adequately ensured and which has excellent temperature sensitivity corresponding to the temperature of the cooling liquid from an engine. A thermo-operating unit 2 is provided with a control valve 2c for controlling an introduction quantity of cooling liquid from a first inflow port 5a via a radiator, corresponding to the temperature of the cooling liquid from a second inflow port 4b via a bypass passage. Within the housing 3 are provided a plurality of guide bodies 4g which are formed extending from the second inflow port 4b side toward a thermo-element 2a, are arranged intermittently around the thermo-element 2a, and which support the thermo-element 2a in such a way as to be capable of moving in an axial direction, and cooling liquid rectifying claws 4h arranged spaced apart from the thermo-element 2a between the guide bodies 4g, wherein a detoured passage 4i for the cooling liquid, directed from the second inflow port 4b side toward an outflow port 4c, is formed by forming gap portions between the guide bodies 4g and the cooling liquid rectifying claws 4h.

The invention discloses a temperature-sensitive gel and a preparation method thereof, and belongs to the technical field of gels, and the temperature-sensitive gel provided by the invention is prepared by mixing a temperature-sensitive material N-isopropylacrylamide containing double bonds with a self-made modified cross-linking agent, then adding a photoinitiator 2-hydroxy-1-[4-(2-hydroxyethoxy) phenyl]-2-methyl-1-acetone, then adding a photoinitiator 2-hydroxy-1-[4-(2-hydroxyethoxy) phenyl]-2-methyl-1-acetone, and finally adding an initiator 2-hydroxy-1-[4-(2-hydroxyethoxy) phenyl]-2-methyl-1-acetone to prepare the temperature- and finally, carrying out cross-linking polymerization under the action of ultraviolet rays with the wavelength of 365 nm. Through detection, the prepared temperature-sensitive gel has excellent temperature-sensitive characteristics, meanwhile, a modified cross-linking agent is prepared by improving the cross-linking agent, then the modified cross-linking agent is applied to the preparation process of the temperature-sensitive gel, and the finally prepared temperature-sensitive gel has the advantages that the antibacterial performance is remarkably improved on the basis that the excellent temperature-sensitive characteristics are reserved; the temperature-sensitive gel prepared by the invention can be applied to the field of repairing of wounds of skin, oral cavity, esophageal mucosa and the like.

This invention relates to a flexible wearable thermosensitive fiber, its preparation method, and its applications. The flexible wearable thermosensitive fiber includes a conductive fiber and a thermosensitive coating, an external electrode layer, and an encapsulation protective layer sequentially coated on the outer surface of any one end of the conductive fiber. The conductive fiber and the external electrode layer are not in contact. An insulating layer is also disposed between the thermosensitive coating and the external electrode layer within the axial projection area of ​​the conductive fiber. The thermosensitive coating is based on a polymer matrix, and the matrix includes a thermosensitive material. The flexible wearable thermosensitive fiber also includes a detection end lead, which penetrates the encapsulation protective layer and forms an electrical connection with the external electrode layer. This flexible wearable thermosensitive fiber has low resistance and excellent mechanical properties, enabling sensitive, accurate, and rapid temperature detection. Wearable temperature sensors made from this flexible wearable thermosensitive fiber can be well applied in the medical field for body temperature detection.
