Embodiment
Specify the specific embodiment of the present invention below.
Hereinafter, 2-acrylamide-2-methyl propane sulfonic acid is represented with AMPS.
The raw material of using among the present invention, other component in binding agent the multipolymer of AMPS and vinyl monomer can buy industrial goods.
AMPS and vinyl monomer prepare by Raolical polymerizable, and adopt the method for solution polymerization, and solvent is dimethyl formamide (DMF), and concrete steps are as follows:
At first AMPS and another kind of vinyl monomer are added in the reactor according to a certain percentage, the molar ratio scope of AMPS and vinyl monomer is 6: 4-4: 6, and add an amount of solvent DMF monomer is all dissolved; Add the initiator Diisopropyl azodicarboxylate, add-on is the 3%-6% of reactant quality; 60 ℃-80 ℃ were reacted 12 hours-24 hours down, and logical nitrogen protection; After reaction finishes, do precipitation agent, the polymer precipitation of AMPS and another vinyl monomer is come out, obtain prepared water-soluble polymers solid with drying after filtration with acetone or chloroform.Vinyl monomer described here can adopt a kind of in ethyl propenoate, butyl acrylate, vinylbenzene or the acrylamide, but is not limited to that these are several.
According to discovering for many years, the proportion of raw materials relation of ceramic injection material is strict controlled in the following ranges, just can obtain to inject the good fluidity of material, and prevent that effectively injected sample can not produce defectives such as crack, bubbling, spalling in skimming processes.
The composition of raw material and content are, according to Mass Calculation, total amount is 1000 parts: ceramic powder 800-900 part, multipolymer 30-100 part of 2-acrylamide-2-methyl propane sulfonic acid and vinyl monomer, non-soluble polymer 30-100 part, tensio-active agent 5-20 part, softening agent 10-30 part, lubricant 10-40 part.
