Abstract
The invention relates to the technical field of chemical materials, in particular to a powder extrusion forming agent, and aims to provide pollution-free and environment-friendly construction glue powder. The powder extrusion forming agent comprises, by weight percentage, 10-15% of vinyl acetate copolymer, 3-7% of stearic acid, 20-35% of solid paraffin, 5-7% of high-density polyethylene and ethylene, 30-40% of liquid paraffin, 2-5% of plasticizer, and 1-5% of carnauba wax.
Description
Technical field
The present invention relates to the technical field of chemical materials, specifically a kind of powder extrusion forming agent.
Background technology
Along with the development of industrial society, society constantly increases the demand of sintered metal product.Nowadays, powder extruding is the novel forming technique of a kind of powder metallurgy developed rapidly in recent years.The novel forming technique of this powder metallurgy has that product length is unrestricted, density relatively evenly, efficiency advantages of higher, now become one of most effective method such as product of preparing big L/D ratio powder metallurgy pipe, rod, bar, band.But this powder extrusion forming utilizes power injection molding, its injection needed for temperature higher, be not suitable for metallurgy pipe, rod, bar, the band of preparing low temperature.
Summary of the invention
The object of this invention is to provide and a kind ofly inject temperature required lower, environmentally friendly powder extrusion forming agent.
The technical solution used in the present invention is, a kind of powder extrusion forming agent, described each material is by following percentage by weight composition: vinyl acetate co-polymer 10-15%, stearic acid 3-7%, solid paraffin 20-35%, high density polyethylene (HDPE) and ethene 5-7%, atoleine 30-40%, plasticizer 2-5%, Brazil wax 1-5%.
The object of this invention is to provide and a kind ofly inject temperature required lower, environmentally friendly powder extrusion forming agent.
Detailed description of the invention
The present invention is further described with the following Examples.
Embodiment 1, a kind of powder extrusion forming agent, described each material is by following percentage by weight composition: vinyl acetate co-polymer 10%, stearic acid 3%, solid paraffin 20%, high density polyethylene (HDPE) and ethene 5%, atoleine 40%, plasticizer 5%, Brazil wax 1%.
Embodiment 2, a kind of powder extrusion forming agent, described each material is by following percentage by weight composition: vinyl acetate co-polymer 12%, stearic acid 5%, solid paraffin 28%, high density polyethylene (HDPE) and ethene 6%, atoleine 35%, plasticizer 3%, Brazil wax 3%.
Embodiment 3, a kind of powder extrusion forming agent, described each material is by following percentage by weight composition: vinyl acetate co-polymer 15%, stearic acid 7%, solid paraffin 35%, high density polyethylene (HDPE) and ethene 7%, atoleine 30%, plasticizer 2%, Brazil wax 1%.
Should be understood that this embodiment is only not used in for illustration of the present invention to limit the scope of the invention.In addition, should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the protection domain that the application's appended claims limits equally after having read the content that the present invention lectures.
