The application provides a heat-resistant and moisture-resistant degradable PLA adhesive tape, which has a four-layer structure and comprises an inner layer, a substrate layer, a functional layer and a protective layer; the inner layer is a degradable pressure-sensitive adhesive with high viscosity and certain hydrophobicity; the substrate layer is a degradable PLA film or a PLA and PBAT blended film; the functional layer is an electrospun layer, and the electrospun layer is a gradient electrospun film containing CaSO3 with different concentrations; the water absorption salt content is low near the substrate side and high near the outer surface side; and the protective layer is a long-chain silane modified SiO2. The application constructs a wettability gradient distribution from inside to outside, i.e. a hydrophobic substrate-hydrophilic gradient layer-super-hydrophobic outer layer, by using the electrospinning technology; the capillary suction effect of the hydrophilic layer is used to realize the one-way discharge of the edge infiltration of water; and the heat reflection and physical barrier mechanism of the super-hydrophobic coating of the outer layer are combined to synergistically improve the heat resistance and moisture resistance of the adhesive tape, so that the use requirement in a complex environment is met.

The invention relates to the technical field of pipes, in particular to a functional master batch for a high-weather-resistance and high-antifouling net cage pipe as well as a preparation method and application of the functional master batch. The invention relates to a functional master batch for a high-weather-resistance and high-antifouling net cage pipe. The functional master batch for the high-weather-resistance and high-antifouling net cage pipe is prepared from the following raw material components: a flexible solubilizer, a functional filler, a weather-resistant master batch and a functional antifouling agent, the functional filler is titanium dioxide coated hollow glass beads of which the surfaces are modified by a silane coupling agent; the weather-resistant master batch comprises the following raw materials: polyethylene, a light stabilizer, an antioxidant and carbon black. The functional master batch for the high-weather-resistance and high-antifouling net cage pipe has the characteristics of good antifouling property, good weather resistance, long-acting antifouling property and excellent mechanical property of the net cage pipe; the technical problems that an existing net cage pipe is insufficient in weather resistance, fast in heat absorption, high in temperature, prone to degradation in mechanical property and poor in antifouling durability, and the mechanical property and the antifouling property of the net cage pipe are contradictory are solved.
