The invention relates to the technical field of adhesives, in particular to a multifunctional sanitary material hot-melt pressure-sensitive adhesive and a preparation method thereof. The multifunctional sanitary material hot-melt pressure-sensitive adhesive is prepared from the following raw materials in parts by mass: 15 to 16 parts of SBS (Styrene Butadiene Styrene), 4 to 5 parts of SIS (Styrene Isoprene Styrene), 50 to 60 parts of petroleum resin and 20 to 30 parts of softening agent. The hot-melt pressure-sensitive adhesive prepared by the preparation method disclosed by the invention has the strong adhesive property of a structural adhesive and the excellent creep resistance of a rubber band adhesive, can meet the dual requirements of adhesion between sanitary material layers and rubber band fixation, and can improve the performance stability and market competitiveness of a product after being used.

This utility model discloses a system for preparing lyocell fiber spinning dope by modifying wood pulp, including an enzymatic purification kettle, a first washing kettle, a bleaching and impurity removal kettle, a second washing kettle, a pulverizer, a pulper, and a thin-film evaporator. The enzymatic purification kettle is connected to a first connecting pipe, which is equipped with a first delivery pump and a first press. The first press is connected to the first washing kettle, which is connected to a second connecting pipe. The second connecting pipe is equipped with a second delivery pump and a second press, which is connected to the bleaching and impurity removal kettle. The bleaching and impurity removal kettle is connected to a third connecting pipe, which is equipped with a third delivery pump and a third press. The third press is connected to the second washing kettle, which is connected to a fourth connecting pipe. The fourth connecting pipe is equipped with a fourth delivery pump and a fourth press. The fourth press, pulverizer, and pulper are connected in sequence. The pulper is connected to a fifth connecting pipe, which is connected to the thin-film evaporator via a screw delivery pump.

This invention discloses a high-toughness asphalt mixture modified from waste plastics and rubber, and its application. It relates to the field of asphalt mixture preparation technology, comprising 80-150 parts of base asphalt, 2-8 parts of modified waste plastic particles, 4-12 parts of activated waste tire rubber powder, 100-150 parts of aggregate, and 30-40 parts of mineral filler. This invention adds silane-coupled waste plastic particles and microwave-activated waste tire rubber powder to the asphalt mixture, limiting the mass ratio of modified waste plastic particles to activated waste tire rubber powder to 1:(1.5~2). The aggregate and mineral filler fully fill the gaps, synergistically solving the defects of high low-temperature brittleness and insufficient high-temperature performance in asphalt. This results in a mixture with excellent high-temperature stability and low-temperature crack resistance, and significantly improved performance reproducibility.
