The invention discloses a normal-temperature-cured bio-oil starch adhesive for wood and a preparation method thereof, belonging to the technical field of adhesive preparation. The method adopts strong acidic cation exchange resin to catalyze the esterification reaction of bio-oil to obtain starch graft copolymerization Reactive monomers; modified starch by acidolysis oxidation, graft copolymerization and compounding to form the backbone of the main adhesive agent; by adding bio-oil, modify the chemical groups on the main agent skeleton of the adhesive, and at the same time act as fillers, anti-corrosion Agents and other additives, prepared into bio-oil starch adhesives. The starch adhesive has the advantages of normal temperature curing, environmental protection, low cost, good cohesiveness, strong water resistance and excellent storage stability.

The invention discloses a net-rope-and-plug-linked-type landscape anchoring device used for preventing falling type dangerous rock. The net-rope-and-plug-linked-type landscape anchoring device is characterized by comprising a plurality of anchoring units distributed on the periphery of the dangerous rock, a protective net for covering the surface of the dangerous rock and landscape objects attached to the protective net; each anchoring unit comprises a plug and a reverse-pulling cylinder, wherein the plug is inserted and clamped into the reverse-pulling cylinder to achieve connection of the plug and the reverse-pulling cylinder; the reverse-pulling cylinders and a parent rock mass are connected in an anchored mode through mortar; each plug comprises a pencil-shaped body, and each body is provided with a plurality of barb grooves and a plurality of barbs at intervals; the barb grooves of the plugs are cuboid grooves, and the length of the barb grooves is coincident with the length of the barbs; the barbs are hinged to the sides of the barb grooves through studs and meanwhile elastically supported by stretchable devices; the reverse-pulling cylinders of the plugs are rectangular columns, a plurality of barb clamping grooves are evenly formed in each reverse-pulling cylinder, four penetrating reinforcing steel bar holes are preserved in each reversing-pulling cylinder, four penetrating reinforcing steel bars are arranged in each reversing-pulling cylinder, and the barb clamping grooves are wedge-shaped grooves. According to the net-rope-and-plug-linked-type landscape anchoring device, the rock mass of the dangerous rock is not damaged, and construction is rapid and convenient; the net-rope-and-plug-linked-type landscape anchoring device has the advantage of achieving landscape repairing.

The invention relates to a bio-oil starch adhesive for wood, which belongs to the technical field of adhesive preparation. A preparation method comprises the following steps: carrying out acidolysis, oxidation and denaturation on starches by using a hydrochloric acid and an oxidant so as to reduce the molecular weight of the starches and improve the reactivity of the starches; then, adding an emulsifier and a stabilizer into the obtained object, and carrying out graft copolymerization on the obtained mixture and acrylamide under the action of an initiator; adding bio-oil, so that chemical groups on a skeleton structure are modified by using substances such as acid and aldehyde and the like in the bio-oil, thereby obtaining a host adhesive; and finally, adding a crosslinking agent and packing into the host adhesive so as to obtain the bio-oil starch adhesive, wherein the mass part of each raw material component is as follows: 80-120 parts of the starches, 150 parts of the hydrochloric acid, 2-5 parts of the oxidant, 1-3 parts of the emulsifier, 10-20 parts of the stabilizer, 0.3-0.6 part of the initiator, 10-20 parts of the acrylamide, 5-20 parts of the bio-oil, 5-10 parts of the crosslinking agent, and 10-15 parts of the packing.
