Abstract
Novel phenoplast and method for making thereof.The invention belongs to a kind of method of phenoplast being carried out modification.Its main points are that the prescription to present production phenoplast is improved, with lacquer resins, wood powder, urotropine, stearic acid or stearate (or both mixtures), magnesium or magnesium oxide (or aluminium or aluminium sesquioxide), graphite, carbon black by certain recipe ratio knead, plasticate, fragmentation forms.The novel phenoplast that make by the present invention have conduction or semi-conductivity, can eliminate static fully, and its existing phenoplast of some mechanical property ratio are greatly improved, and can replace metal to be applied in electrical apparatus industry and other industry.
Description
The present invention belongs to a kind of method of phenoplast being carried out modification.
The phenoplast of producing have electrical insulating property at present, easily produce static hazard.When plastics produced static because of friction, because its insulativity, its water-absorbent was low in addition, the static that forms is difficult for cancellation, and static focus increases, and makes plastics adsorb dust easily, influence the use properties of goods, but also fire hazardous and other unsafe problem.
The present invention organizes patent through consultancy place of Chinese patent literature service centre by patent, the two worlds of the miniature retrieval of computer and 1983～1987 years more than 20 countries of hand inspection in September, 1987, and the document relevant especially with the present invention all do not arranged.
Purpose of the present invention is carried out modification to existing phenoplast exactly, reduces its surface resistivity, to eliminate static, becomes semiconductor or electric conductor by electrical insulator.The novel phenoplast of gained had both had the electric conductivity of metal, had the good mechanical property and the corrosion resistant chemical property of former plastics again, can replace metal usefulness, to enlarge the range of application of phenoplast.
Main points of the present invention are improved by the prescription to present production phenoplast, with lacquer resins, wood powder, urotropine, stearic acid or Zinic stearas (or its molysite, barium salt, calcium salt), the mixture of also available stearic acid and stearate, magnesium (or magnesium oxide) or aluminium (or aluminium sesquioxide), graphite, carbon black etc. by certain recipe ratio knead, plasticate, broken and make novel phenoplast of the present invention.
Technical recipe: (composition by weight)
100 parts of lacquer resinss
92～110 parts of wood powders
12～12.5 parts of urotropines
1.9～2.2 parts of Zinic stearass (or iron, barium, calcium salt)
3.3～16 parts in graphite
Mg(or MgO), or Al(or Al
2O
3) 2.4～3.4 parts
3.3～8.8 parts of carbon blacks
1.5 parts of stearic acid
Technical process:
1, earlier wood powder, graphite, carbon black were dried by the fire one hour at 60～100 ℃, with 60～140 mesh sieve they are sieved respectively then, to remove macrobead and mechanical impurity.
2, by above-mentioned technical recipe lacquer resins, wood powder, urotropine, stearic acid, Zinic stearas (or its iron, barium, calcium salt), magnesium (or magnesium oxide) or aluminium (or aluminium sesquioxide), graphite, carbon black are put into kneading machine, the time of kneading is 10～20 minutes.
3, the good material of will kneading is poured in the twin-roll plastic mixing mill, plasticates.Plasticating temperature: preliminary roller is 100～130 ℃, and back roller is 90～120 ℃, and the time of plasticating is 2～10 minutes.
4, carry out fragmentation with crusher, promptly make novel phenoplast of the present invention.
Novel phenoplast by the present invention makes have electroconductibility, its surface resistivity＜10
6Ohm can be eliminated static fully, and its physicals and chemical property are greatly improved than the phenoplast of producing at present, can replace metal to be applied in electrical apparatus industry and other industry.
Embodiment:
1, wood powder, graphite, carbon black were dried by the fire one hour at 60～100 ℃, with 60～140 mesh sieve they are sieved respectively then, to remove macrobead and mechanical impurity.
2, technical recipe: (parts by weight)
100 parts of lacquer resinss
95 parts of wood powders
12 parts of urotropines
2.0 parts of Zinic stearass
3.4 parts in graphite
2.8 parts in magnesium oxide
5.6 parts of carbon blacks
1.5 parts of stearic acid
By technical recipe above-mentioned material is joined in the kneading machine and to knead, time of kneading is 10～20 minutes, the good material of will kneading is then poured into and is plasticated in the twin-roll plastic mixing mill, plasticating temperature is: 100～130 ℃ of preliminary rollers, back roller is 90～120 ℃, the time of plasticating is 2～10 minutes, carries out fragmentation with crusher at last, promptly gets novel phenoplast of the present invention.As follows through recording its every performance:
Surface resistivity: 2.5 * 10
6Ohm
Flexural strength: 729.4 kilograms per centimeter
2
Shock strength: 5.53 kilograms per centimeter
2
Hardness (Bu Shi): HB=57.19 kilogram/millimeter
2
Shrinking percentage: 6 ‰
