The present application belongs to the technical field of glass fiber sizing agent, and particularly relates to an anti-creep glass fiber sizing agent and a preparation method thereof. The anti-creep glass fiber sizing agent comprises effective components and water, and the solid content of the anti-creep glass fiber sizing agent is 3-12%. The effective components comprise the following components according to weight percentage: maleic anhydride modified long-chain branched polyolefin wax 65.5-86.9 wt.%, coupling agent 5-10 wt.%, nucleating agent 1-8 wt.%, physical cross-linking component 5-12 wt.%, initiator 0.1-0.5 wt.%, and surfactant 2-4 wt.%. The present application can effectively solve the problem of insufficient anti-creep ability of the glass fiber reinforced polypropylene material in the prior art, and at the same time, the material has good mechanical properties and fatigue resistance, which plays an important role in improving the long-term dimensional stability of the polypropylene material.

This invention relates to the field of ion sieve technology, providing a titanium-based lithium-ion adsorbent, its preparation method, and its applications. The invention involves pyrolyzing NH2-MIL-125(Ti), then mixing it with lithium carbonate for calcination, granulating it using an ethylene-vinyl alcohol copolymer as a binder, and finally acid washing to obtain the titanium-based lithium-ion adsorbent. This invention integrates metal-organic framework (MOF)-derived carbon intercalation, nitrogen doping, and polymer-assisted granulation into a single process, preparing a particulate adsorbent with a hierarchical porous structure, strong hydrophilicity, and abundant active sites, showing great potential for industrial applications. Example results show that the adsorbent of this invention, under conditions of pH=12 and 25℃, exhibits a high Li-ion concentration of 24 h. + The adsorption capacity reached 33.95 mg / g. After five cycles of adsorption and desorption, the adsorption capacity could still reach 96.9% of the initial adsorption capacity, and the titanium dissolution loss in each cycle was only about 0.4%.
