Temperature-variable controlled-release gel composite material and application thereof in cigarette filter stick

The invention provides a temperature-variable controlled-release gel composite material and application thereof in a cigarette filter stick, and belongs to the technical field of preparation of cigarette holders. A preparation method comprises the steps that gel is heated and melted; then the gel is conveyed into an infiltration tank with a heat preservation function; a common aroma-increasing core wire is wound through an unwinding mechanism and then guided to the infiltration tank, the core wire is immersed into the liquid gel, and the concentration of the liquid gel is adjusted so that the thickness of a gel layer attached to the surface of the aroma-increasing core wire can be larger than or equal to the diameter of the aroma-increasing core wire; then cooling and drying are conducted on the infiltrated aroma-increasing core wire, the gel is solidified into a solid which is attached to the surface of the aroma-increasing core wire, and accordingly the temperature-variable controlled-release gel composite material is obtained. According to the composite material prepared from the gel and the prepared filter stick, the forming degree and the aroma locking effect are good, production arrangement of the filter stick is facilitated, obtained products are relatively rich, and quick volatilization of the gel which is simply applied to the filter stick during smoking can be slowed down, so that a whole cigarette has a relatively balanced mouth feel.

PU smell removing polyurethane coating as well as preparation and application thereof

The invention provides a PU smell removing polyurethane coating which consists of a component A, a component B and a component C, wherein the component A comprises a crylic acid modified polyester resin, n-butyl acetate, a defoaming agent, a dispersing agent, a leveling agent, a delustering agent and an anti-settling agent; the component B comprises polyisocyanates, a co-polymer and n-butyl acetate; the component C comprises n-butyl acetate, dimethyl carbonate, propylene glycol monomethyl ether acetic ester and dimethylbenzene. According to the PU smell removing polyurethane coating, by modifying the double-component hydroxy acrylic resin, the characteristic that the hydroxy acrylic resin is rapid in releasing a solvent is maintained, and the fullness of the hydroxy acrylic resin is remarkably improved; the PU smell removing polyurethane coating provided by the invention not only has the characteristics of rapid drying speed, high hardness and excellent fullness, but also is small in smell. A good synergistic effect of various components of the coating is brought into play, and particularly through interaction and balancing of the resin, the solvent and the hardening agent, the coating is free of conspicuous smell after the coating is constructed and dried for 48 hours.

Method for producing acrylic ester copolymer

ActiveCN101544725AReasonable adhesionHigh tensile strengthEmulsionAdhesive
The invention relates to a method for producing acrylic ester copolymer, which belongs to the technical field of organic adhesives. The method comprises the following steps: preparing a monomer solution; preparing an emulsifying agent solution; preparing an emulsion; preparing a bed charge solution; preparing an initiator solution; and heating up the bed charge solution to a temperature of between 40 and 50 DEG C, adding the initiator solution, and stirring the mixture sufficiently to obtain a semi-finished product; heating up the semi finished product continuously to a temperature of between 80 and 85 DEG C, when the reflux inside temperature reaches between 85 and 90 DEG C, dripping the emulsion and the initiator solution for 1 to 5 hours, then keeping temperature for 1 to 3 hours, cooling the mixture to a temperature of less than 40 DEG C, and filtering the mixture to discharge the materials. The method has the advantages of reasonable design, simple operation and low production cost; and the obtained acrylic ester copolymer adhesive has reasonable adhesive property and unobvious burning peculiar smell, improves the performances of tensile strength, flexible bendability, appearance and color and the like of a gasket if the acrylic ester copolymer adhesive is applied to a gasket, reduces the burning peculiar smell, is convenient for subsequent packaging processing of a catalyst product and the like, and makes the quality of gasket products reach or exceed that of similar products in other countries.

Method for extracting water-soluble haematochrome from lovastatin crystallization mother liquor

The invention provides a method for extracting water-soluble haematochrome from lovastatin crystallization mother liquor. The method comprises the following steps of: 1) carrying out concentration on the lovastatin crystallization mother liquor; 2) carrying out alkaline hydrolysis on the concentrated liquor; 3) adding a first precipitator in the hydrolysis liquor so that colloidal impurities in the hydrolysis liquor are precipitated, filtering the obtained object, and collecting filter liquor; 4) adding a second precipitator in the filter liquor so that water-soluble lovastatin acid salts are converted into water-insoluble lovastatin acid salts, filtering the obtained object, and collecting filter liquor; 5) acidifying the filter liquor by using an acidifying agent until the pH value of the filter liquor is below 3.5, and carrying out organic solvent extraction so as to obtain extract liquor; 6) carrying out concentration on the extract liquor so as to obtain concentrated liquor; 7) carrying out alkalization on the concentrated liquor by using an alkali solution, filtering the obtained object, and collecting filter liquor; and 8) carrying out concentration and drying on the filter liquor so as to obtain the water-soluble haematochrome. According to the invention, water-soluble haematochrome is successfully extracted from the lovastatin crystallization mother liquor for the first time; and the method is simple in process, has low requirements for equipment, and is suitable for industrialized continuous production.

Preparation method of fish scale collagen and application of fish scale collagen as antioxidant and enzyme inhibitor

The invention provides a preparation method of fish scale collagen. The preparation method comprises the following steps: boiling fish scales to a pasty state, then adding compound protease for hydrolysis, keeping a temperature at 40-45 DEG C in a hydrolysis process, keeping a pH value at 6.0-7.0 in a hydrolysis process, adjusting the pH value to 6.0-6.5 after hydrolysis, carrying out primary filtration, collecting a filtrate, carrying out membrane filtration on the filtrate to obtain thinner liquid, subjecting the obtained thinner liquid to decoloration treatment while the pH value is kept at 4.0-4.5 in a decoloration process, adjusting the pH value to 6.0-6.5 after decoloration to obtain decolored material liquid, concentrating the decolored material liquid to obtain a concentrated liquid with a solid content of 21-28%, and then conducting spray drying to obtain the powdery fish scale collagen. The fish scale collagen obtained by the invention can also be used as an antioxidant and a carbohydrase inhibitor for practical application. The method provided by the invention is efficient in processing, and meanwhile, the appearance and smell characteristics of the fish scale collagen are improved.
