The invention provides a silicon grease-free mold release agent for a special-shaped rubber pipe. The silicon grease-free mold release agent comprises the following components of 26-100 parts of a polyether surfactant, 1-5 parts of an antirust agent, 5-15 parts of alkyl benzene sulfonic acid monoethanolamine and 5-15 parts of fatty acid methyl ester ethoxylate sulfonate. The mold release agent provided by the invention does not contain an organic silicon component, and can meet various requirements of high-temperature resistance, lubrication property, water solubility, no corrosion, no residue, water-borne environment friendliness and the like on a mold release agent for a production line for rubber pipe molding.

The present invention discloses applications of lycopene in promotion of yogurt fermentation and maintaining of stability of viable count within a yogurt shelf life. The present invention further discloses a lycopene-containing yogurt, wherein the raw materials comprise milk or milk powder and water, and lycopene. The present invention further discloses a preparation method of the lycopene-containing yogurt, wherein the method comprises: adopting milk or milk powder as a main raw material, adding lycopene, carrying out homogenization and sterilization, and carrying out strain fermentation to produce the yogurt. According to the present invention, the lycopene is added to the yogurt to shorten the fermentation time and reduce the fermentation risk; the lycopene is added to the yogurt to keep the viable count of the yogurt; and the obtained yogurt has characteristics of smooth and delicate tissue state, gloss, no water dropping, pure flavor, good taste and good stability, and cannot produce unacceptable phenomena such as stratification, precipitation and fat floating after the yogurt is stored for more than or equal to 30 days in a low-temperature storage manner.

The biodegradable gadolinium complex-containing polymer of the invention has a high relaxation rate, has excellent effect as a magnetic resonance imaging contrast agent, is degradable, nontoxic, has good biocompatibility, and has good clinical application prospects.

The invention discloses hyperbranched hydroxyl polyester resin, and a preparation method and an application of the hyperbranched hydroxyl polyester resin.The preparation method of the hyperbranched hydroxyl polyester resin comprises the following steps: 1) according to molar fraction, 1 part of dicarboxylic anhydride and 2-4 parts of polyhydric alcohol are mixed in a reaction kettle, paratoluenesulfonic acid and an organic solvent are added for reaction at 105-125 degrees under nitrogen protection, then 4-10 parts of phthalic anhydride are added, and reaction for 2-3h is carried out; and 2) according to molar fraction, 6-10 parts of epoxy compounds are added to a matrix prepared in the step 1), a catalyst and an organic solvent are added for reaction for 4-6h at 105-1130 degrees under the nitrogen protection till an acid value is less than 10mgKOH / g, and cooling and discharging are carried out. The solid content of the hyperbranched hydroxyl polyester resin reaches above 70%, and the viscosity is 3000-12000mPa.s. High solid-content bi-component polyurethane dope prepared with the adoption of the hyperbranched hydroxyl polyester resin has high construction solid content, low VOC content, high film hardness, good heat resistance and outstanding anti-corrosion property.

The present invention provides an application of Eucalyptus multibract essential oil and its composite bacterial agent in the preparation of an insect repellant for seawater fish. Not less than 5×10 8 CFU / g of Streptomyces griseus HL‑50, wherein the preservation number of Streptomyces griseus HL‑50 is CGMCC No.18424, and the main active ingredient of Eucalyptus multibractosa eucalyptus essential oil is 1,8‑cineole. The eucalyptus eucalyptus essential oil compound microbial agent of the present invention is simple to prepare and use, and it only needs to be uniformly mixed in the edible feed of seawater fish according to the dosage of 0.5-1.5 kg / ton of feed and continuously fed for 4-7 days to achieve It can effectively drive away various parasites infected by seawater fish and has antibacterial effect, and the compound bacterial agent is non-toxic and harmless, is suitable for long-term use of fish, reduces breeding costs, and has broad application prospects.

The invention provides a biodegradable poly-HPMA-Gd magnetic resonance imaging probe, which inserts the enzyme-sensitive polypeptide GFLG into the poly-HPMA main chain structure; the molecular weight of the prepared polymer is basically controllable, and the molecular weight polydispersity coefficient ( PDI) is low; and linearized HPMA-DOTA-Gd is obtained by coupling with Gd(III). The probe is a high-efficiency biocompatible nanoscale MRI magnetic resonance imaging probe, which can be used for clinical tumor diagnosis and adjuvant therapy.
