Abstract
The present invention relates to thermosol powder containing colophony and lac for cutting precise lodestones and a preparing process. According to weight parts, the thermosol powder comprises 30 to 50 shares of rosin, 30 to 50 shares of lac, 3 to 8 shares of polymerized rosin, and 2 to 5 shares of light calcium carbonate, the surface of which is treated by silicone. The present invention has the preparing process: firstly, the surface of the light calcium carbonate is treated by silicone organic solution; then, the respectively pulverized rosin, lac and polymerized rosin are taken to be placed into a mixer; after agitation, the light calcium carbonate which is treated by the silicone on the surface is added, and after the mixed solution is continuously agitated for one hour, the thermosol powder can be obtained after discharge. The thermosol powder can be stored at normal temperature; the performance remains unchanged, and the usage is convenient.
Description
The present invention relates to contain hot-melt adhesive powder and the method for making thereof of rosin and lac, especially as incisory hot-melt adhesive powder and the method for making thereof that contains rosin and lac of accurate magnetite.
Lac is the good natural resin of a class character, is usually used in the priming paint of wood furniture; Also be used as tackiness agent (Wang Mengzhong, Huang Yingchang chief editor, " the adhesive applications handbook of top grade, special purpose, Chemical Industry Press, Beijing, 1987, first version, the 86th page), 1976, India has the people to propose with lac or modified shellac as all kinds of caking agents, but product all is not a powdered form, and [Li Shenggui translates, the Wang Dingxuan school also to be not used in metal cutting, " woodsization science and technology ", No.5:60 (1976)].Rosin also is a class natural resin, and its character is crisp, hard, though certain bonding force is arranged, also be useful on the report (Wang Mengzhong of caking agent, the Huang Yingchang chief editor, " adhesive applications handbook, Chemical Industry Press, Beijing, 1987, first version, the 85th～86 page), but can't be separately occur as bonding material, especially not under intense mechanical cutting, vibration as the report of caking agent.
It is directly evenly to trickle down on the magnetite surface through screen cloth with Powdered that accurate magnetite cutting sticks with glue agent, behind the multilayer build-up, inserts baking oven, treat the hot melt adhesive fusing after, take out, cooling, to be cut.The special-shaped magnetite of a large amount of uses in accurate miniature motor and loudspeaker, it is very high to requirement on machining accuracy to cut this type of magnetite, and common tackiness agent is difficult to reach its harsh requirement.Rosin and lac can be formed can satisfy the tackiness agent that accurate special-shaped magnetite cutting processing requires, but the product that these two kinds of starting material are formed can not exist with powdered form, must pulverize or melt them and could use at the magnetite cleavable site.Though imported product can exist with powdered form, can only store half a year by low temperature (below 10 ℃), otherwise can lose performance, influence is used.
The purpose of this invention is to provide a kind of accurate magnetite cutting that contains rosin and lac and use hot-melt adhesive powder, it not only can make powdered form, and can storage at normal temperature, performance and use are had no adverse effects, can further simplify, handled easily, save the energy, raise the efficiency.
Another object of the present invention provides the method for making of this hot-melt adhesive powder.
The accurate magnetite cutting hot-melt adhesive powder that contains rosin and lac provided by the invention is counted by weight, and its composition comprises:
30～50 parts of rosin,
30～50 parts of lacs,
3～8 parts of polymerized rosines,
Through 2～5 parts of silicone oil surface-treated light calcium carbonates,
Wherein silicone oil accounts for 2～8% of light calcium carbonate weight, is good with 5～8%.
The abietic acid weight content is good with 25～60% in the above-mentioned rosin;
Used silicone oil is advisable between 1～50PaS with viscosity, especially can be that dimethyl silicone oil (also claims polydimethylsiloxane, Dimethicone).The too high difficulty of then disperseing of silicon oil viscosity.
The method for making of the hot-melt adhesive powder that contains rosin and lac provided by the present invention is as follows: at first light calcium carbonate is carried out surface treatment with silicone oil organic solution, getting then, rosin, lac, the polymerized rosin of separated pulverizing place mixing tank, stir down and add through silicone oil surface-treated light calcium carbonate, continue to stir after one hour, discharging can get the accurate magnetite cutting hot-melt adhesive powder that powdered form contains rosin and lac.
Silicone oil organic solution generally can adopt acetone to make solvent, and the silicone oil weight concentration is 2～8% to be advisable, and is good with 5～6%.
Provided by the invention as the incisory tackiness agent that contains rosin and lac of accurate magnetite, since wherein play the effect of solid dispersion through silicone oil surface-treated light calcium carbonate, therefore can prepare in advance and become powdered form, and can storage at normal temperature, reach 1～2 year storage period, property retention is constant; Simultaneously, the bonding strength of this hot melt adhesive is all greater than 110N/cm
2, than 80～90N/cm of conventional products
2High.This hot melt adhesive is simplified, has been made things convenient for use, has saved the energy, has improved efficient.
The umber of following examples, content are all by weight.
