The invention discloses an oil-resistant cold-resistant flame-retardant polyvinyl chloride material and a preparation method thereof. The polyvinyl chloride material is prepared from the following raw materials in parts by weight: 100 parts of PVC resin, 40-60 parts of a plasticizer, 30-50 parts of a flame retardant, 15-25 parts of a cold-resistant agent, 10-20 parts of an oil-resistant agent, 5-10 parts of a heat stabilizer and 2-5 parts of a lubricant. Wherein the flame retardant is a composite flame retardant composed of aluminum hydroxide, magnesium hydroxide and antimony trioxide, the cold-resistant agent is an ethylene terpolymer, and the oil-resistant agent is a polar copolymer of acrylonitrile and butadiene. The material is excellent in comprehensive performance, the low-temperature impact performance can pass minus 40 DEG C, after an oil resistance test, the mechanical property loss is extremely small, the oxygen index is maintained to be about 30%, the stable mechanical property and thermal stability are achieved, collaborative optimization of oil resistance, cold resistance and flame retardance is achieved, and the service life of the material is prolonged. The cable is suitable for cable preparation under complex working conditions such as automobile engine cabins, industrial equipment in extremely cold areas and petrochemical engineering, the preparation process is high in controllability, and industrial production is easy.

The utility model discloses a kind of feeding equipment for environmental protection plastic woven bag production, it is related to feeding equipment technical field;And the utility model includes feeding pipe, the top surface of feeding pipe is fixed with fixed box, L-shaped plate is slidably arranged in the fixed box, the side of L-shaped plate is fixed with frame, limiting roller is rotatably arranged in the frame, filtering frame is slidably arranged in the fixed box, limiting roller can be rolled in filtering frame, the top surface of fixed box is fixed with fixed frame, the side of fixed frame is fixed with second motor, the output of second motor is fixed with rotating shaft, by the mutual movement of two L-shaped plates, in turn make frame drive limiting roller roll on the top surface of filtering frame, in turn can the caked raw materials be scattered, then the caked raw materials can fall from filtering frame, avoid the caked raw materials in drawing-in machine difficultly fully plasticization, improve the uniformity of drawing-in, no fracture phenomenon appears.

The application discloses a glass fiber reinforced polypropylene material, a preparation method and application, and belongs to the technical field of polypropylene engineering plastics. The material contains, in terms of weight parts, 40-70 parts of polypropylene resin, 20-50 parts of alkali-free continuous long glass fiber, and compounded antioxidants, compatibilizers, scratch-resistant agents, heat-resistant agents and light stabilizers. The alkali-free continuous long glass fiber has a diameter of 10-14 microns, a breaking strength of greater than or equal to 3000 MPa, and a linear density of 2400 tex or 3600 tex. The material has high strength, aging resistance and low-temperature impact resistance, and is suitable for automobile structural parts.

This invention discloses a continuous stirring friction deposition additive manufacturing apparatus, belonging to the field of metal additive manufacturing technology. It includes: a housing; a spindle assembly with an axial channel for conveying additive rods and driven to rotate by a drive mechanism; and a continuous feeding mechanism located on the feed side of the spindle assembly, used to continuously feed the additive rods into the axial channel of the spindle assembly and apply an axial thrust to the additive rods, causing them to move towards the working end of the spindle assembly. It has the advantages of achieving continuous and stable rod supply, improving the automation level of feeding, reducing jamming risks, and enhancing deposition forming quality and process stability.
