Abstract
A kind of modified nylon materials that adopts is that its hot-mounting process flow process of nylon ball grinder that raw material is made is: melt dewater system active material → co-catalyst mix with filler → raw material is at a die for molding polymerization → heat treatment → tank body and a jar end hot charging combination forming, nylon ball grinder of the present invention provides a kind of high strength, good toughness, wear-resisting nylon ball grinder for the electronic ceramics industry.Quality, the noise that it can improve the electronic component of being produced be low, improve working environment, reduce production costs, and tangible economic benefit and social benefit are arranged.
Description
The present invention is that a kind of modified nylon materials that adopts is nylon ball grinder and the hot-mounting process thereof that raw material is made.
The electronic ceramics industry is in production of electronic components processes such as manufacturing ceramic capacitor at present, want to make tens kinds of porcelains such as titanium dioxide, brium carbonate, strontium carbonate, magnesium carbonate and solution to mix ultra-fineization and homogenising in proportion, to satisfy ceramic performance and the electrical property of making various electronic components, just must adopt ball mill to drive ball grinder and finish by ball mill grinding.The two kinds of ball grinders that adopt, a kind of is porcelain jar, though its anti-wear performance height, fragility is big, and is fragile, and cost an arm and a leg, raw material and porcelain jar during to mill noise big, a small amount of porcelain powder under the mill is mixed in the raw material and can't decomposes, and directly influences the product quality of electronic component.Another kind is the polyvinyl chloride jar, and it is easy to wear, and service life is short.
The present invention is the nylon ball grinder of making by hot-mounting process, and purpose is the nylon ball grinder that the enforcement nylon high strength that filling-modified processing is made, good toughness, wear-resisting wiping are provided for the electronic ceramics industry.
Nylon ball grinder of the present invention and hot-mounting process content Description thereof:
Nylon ball grinder of the present invention is to handle a kind of nylon ball grinder with high-wearing feature and obdurability of making to implementing the filled nylon modification in the nylon polymerization course of reaction, it is characterized in that the production hot-mounting process of modified cast mylon ball grinder is: melt dewater system active material → co-catalyst mixes with filler → raw material is at a die for molding polymerization → heat treatment → tank body and a jar end hot charging combination forming.
Nylon ball grinder of the present invention has characteristics such as high-wearing feature and obdurability, noise be low, can improve the electronic component of being produced quality, improve working environment, reduce production costs, tangible economic benefit and social benefit are arranged.
Embodiment:
Nylon ball grinder is produced the hot-mounting process flow process:
Melt dewater system active material → co-catalyst mix with filler → raw material is at a die for molding polymerization → heat treatment → tank body and a jar end hot charging combination forming.
1, the melt system active material that dewaters:
Adopting caprolactam and NaOH is raw material, the weighing caprolactam is poured in the reactor in proportion, be heated to 80～100 ℃, add proper amount of sodium hydroxide, the beginning decompression dehydration when pressure is the 760mmHg post, continues to be heated to 140～160 ℃ in the reactor, there is Bao Xiang And to continue to open the reactor feeding mouth after 30～90 minutes in the question response still.
2, co-catalyst mixes with filler:
But adopt co-catalyst row sodium glue and filler rare earth liquid, tetrafluoro liquid, titanium dioxide, stir in the adding reactor, stop heating then.
3, raw material is in the die for molding polymerization:
Mixed raw materials poured into to give hot temperature in advance be polymerization in 140 ℃ the mould, went into insulating box 2～3 hours, polymerisation gets final product the demoulding after stopping, and takes out monomer cast nylon ball grinder blank, blank as shown in drawings, tank body (1), jar end (2).
4, heat treatment:
The water that monomer cast nylon ball grinder blank is put into 100 ℃ boiled 8～10 hours.
5, tank body and jar end hot charging combination forming:
A casting mold modification of nylon ball milling tank body and a jar end blank are processed through turning, and mouthful planar inverted 45 degree oblique angles in tank body (1) lining are apart from chamfering 10～20mm place processing one spill trough with straight angle.Convex right angle platform shape is processed into by the tank body corresponding size in jar end (2), then tank body is put into 100 ℃ of water and is boiled 15～20 minutes, takes out tank body and is placed on the forcing press, with steadily being pressed at the bottom of the jar among the tank body, finishes hot charging processing rapidly.
