Disclosed here is a composition containing menthol and menthyl lactate, and its preparation method and its applications as a cooling agent and a flavoring agent.The present invention provides a composition characterized in that it comprises menthol and menthyl lactate in a ratio by weight in the range of 1:4˜4:1 and the corresponding crystallization point is below room temperature of 25° C. Such composition has the advantages of being liquid at room temperature; easy to use as a cooling agent or a flavoring agent; no need to use heat to melt menthol and menthyl lactate, which not only saves time, money and heating equipment, but also simplifies manufacturing process and can be used in cold processes at room temperature. The composition can be used as a cooling and / or flavoring agent and / or a fragrance ingredient in toothpaste, mouthwash, fragrance, cleansers, shaving cream, after shave products; shampoo, deodorant, antiperspirant, bath products, drinks, confectionary products, tobacco, pharmaceutical, foods, flavoring and fragrance products.

The invention belongs to the technical field of high polymers and relates to a high-strength high-toughness low-odor polypropylene composition and a preparation method and usage thereof. The high-strength high-toughness low-odor polypropylene composition comprises the following components in parts by weight: 50 to 80 parts of polypropylene, 2 to 9 parts of compatilizer, 0 to 10 parts of thermoplastic elastomer, 0.1 to 0.5 part of antioxidant, 0.2 to 1 part of deodorant and 15 to 35 parts of glass fiber. The composition selects low-odor homopolymerized and copolymerized polypropylene matrix resins, selects a low-odor compatilizer and a reactive deodorant simultaneously, and is simple in production process flow, high in production efficiency, continuous in production process and stable in product quality. The composition maintains the advantages of the polypropylene matrix, and additionally has the capacity of enhancing the strength and the toughness are improved, and reducing the odor is reduced, so that the composition has the comprehensive performance of high strength, high toughness and low odor; and moreover, the requirement on the automotive trim comfort can be well met, and the composition has a good application prospect.

This invention is directed to systems, devices and methods for treating organic-containing sludges and converting such sludges to high value fertilizers containing both inorganic and organic fertilizer components, which creates an inorganically-augmented bioorganic fertilizer. The invention describes methods to create a thixotrophic or paste-like material via the application of mixing energy to the organic sludge followed by an alkaline treatment and a subsequent ammoniation. The invention further describes a method to increase the plant nutrient content in the organic containing product to a level which permits the finished granular fertilizer product to compete in the commercial agricultural fertilizer marketplace. Further, the invention reduces odors associated with said organic-containing sludges.

The invention discloses an antibacterial and low-odor decorative polypropylene material used in a saloon car and a preparation method thereof, wherein the material comprises the following components in percentage by weight: 60 to 80 percent of polypropylene, 1 to 20 percent of elastic body, 10 to 30 percent of talcum powder, 1 to 5 percent of photocatalytic micro-powder, 0.5 to 2.0 percent of antibacterial agent, and 0.3 to 1.0 percent of odor absorbent. The polypropylene material can keep low odor enduringly, has antibacterial and mould-proof functions, and has the advantages of strong bactericidal power, quick disinfectant effect, good durability, good stability, no secondary pollution and the like. According to the invention, odorous small molecules such as paraffin, olefins, arenes, amine, phenol, thiol, peroxide, aldehydes, ketones and the like can be effectively removed.

The invention discloses a polypropylene combination with low smell and diffusion and a preparation method thereof. The polypropylene combination with the low smell and diffusion comprises the compositions as follows: 37-88 percent of polypropylene resin, 5-30 percent of a toughener, 0-40 percent of mineral filler, 0.5-5 percent of medusa particle and 0.1-3 percent of an assistant. The preparation method comprises the steps as follows: the polypropylene resin, the toughener, the mineral filler and the assistant are uniformly mixed in a high mixing machine for 1-3 minutes, places in a main feeding hole of an dual-screw extruder, added with the medusa particles from a side feeding hole, molten, extruded, pelletized and dried at a temperature controlled within 200-215 DEG C and under the rotation speed condition of 450 round / minute, so that the polypropylene combination with the low smell and diffusion is obtained. According to the invention, the medusa particles adopting high-melts foamed PP as a carrier is used as a stripping agent, various kinds of volatile small molecules and organic compounds which are generated during processing can be effectively removed, the prepared polypropylene combination has the characteristics of low smell and diffusion, and can satisfies the demand of automobile for inner decoration.

The invention belongs to the field of chemical synthesis and in particular relates to a spraying and wind leaking stoppage polyurethane combined polyether for a coal mine as well as preparation and use methods thereof. According to the invention, the polyether is prepared through formulation regulation by using HCFC (hydrochlorofluorocarbon)-365mfa and / or HCFC-245fa as foaming agents, is free of fluorine and is environment-friendly; because the boiling point of HCFC-245fa is low, prepared foam is good in size stability; a reaction type amine catalyst with low VOC (volatile organic compound) and low smell is applied, thus the problem of irritative smell is solved; and the foam prepared by using a fire retardant is good in fire retardant property, and an antistatic agent is added so as to improve the problem of high resistance on the surface of polyurethane foam.
