Abstract
The invention discloses a binder for injection molding of Sialon ceramics. The binder is composed of the following components by the mass percentage: 30-60% of a wax based binder, 10-40% of vegetable oil, 2-10% of a compatilizer, and 1-10% of a surfactant. The binder adopts the wax based binder, can improve the wettability on a Sialon ceramic powder, and has lower viscosity and enough strength. The binder can make the loading capacity of the Sialon ceramics reach more than or equal to 60%, has good conformality, is easy to degrease, and avoids generation of degreasing defects.
Description
Technical field
The present invention relates to Sialon Ceramic Powder Injection Molding field, particularly relate to a kind of binding agent for Sialon ceramic injection molding.
Background technology
Sialon is the general name of the multiple compounds group be made up of Si-Al-O-N system.Sialon pottery has the performances such as excellent erosion resistance, resistance to sudden heating, hot strength, electric simulation strength, chemical stability, be a kind of high performance ceramic material of excellence, can be used on the fields such as machinery, chemical industry, metallurgy, aerospace, medical science, biology, automobile.
Injection molding technology is a kind of near-net-shape technology, can manufacture complex-shaped, dimension precision requirement is high, the goods produced in enormous quantities, even density, respectively to contraction phase with, similar to precision casting, and precision and surfaceness good, without the need to following process.Utilize injection molding technology to prepare Sialon pottery, by the forming requirements regulating binding agent kind and content to meet powder, prepare various complicated shape fine ceramics structural part, raw material availability is high, and cost is low, is applicable to industrialization and produces.
The selection of binding agent can affect the filling of powder particle, reunion, batch mixing, rheological characteristics, shaping, degreasing, dimensional precision, defect and the final performance of product.Use wax-based binder can contribute to mixing and be shaped in wetting powder surface, use tensio-active agent volume can set up interface bridge to reduce compound viscosity and to increase the solid load of powder between powder and binding agent, there is the advantages such as good rheological characteristics, injection forming and conformality are good, easy degreasing.
Summary of the invention
The present invention aims to provide a kind of binding agent for Sialon ceramic injection molding, and this binding agent and silicon carbide powder wettability well, can improve powder loading, have the advantages such as conformality is good, easy degreasing.
The object of the invention to solve the technical problems realizes by the following technical solutions.According to a kind of binding agent for Sialon ceramic injection molding that the present invention proposes, it is characterized in that being made up of following raw material by weight percentage:
The object of the invention to solve the technical problems also can be applied to the following technical measures to achieve further.
Aforesaid a kind of binding agent for Sialon ceramic injection molding, described wax binding agent is paraffin or carnauba wax.
Aforesaid a kind of binding agent for Sialon ceramic injection molding, described compatilizer is polyethylene or polypropylene.
Aforementioned a kind of binding agent for Sialon ceramic injection molding, described tensio-active agent is stearic acid (SA) and ester derivative thereof.The raw materials used kind of binder formula provided by the invention is few, and cheaper starting materials is easy to get, good to Sialon pottery wettability, easily remove and have the good feature of environmental protection.
