Abstract
Disclosed is a composite ball made by tungsten and a high polymer material. The composite ball made by tungsten and high polymer material is safe in use and has the environmental protection effect. The technical scheme is that the composite ball made by tungsten and high polymer material is characterized in that the composite ball made by tungsten and high polymer material is composed of the following raw materials of part by weight: (1) tungsten powder accounts for 90-95 parts; (2) Compound of stainless steel powder, copper powder and tin powder account for 2-3 parts in total. (3) Hytrl dupont and Nordel dupont compound account for 3-4 weight parts in total. The invention further discloses the manufacturing method.
Description
Technical field
The invention belongs to military affairs or sports and use the bullet structure field, especially a kind of use safely, have a composite balls of utilizing tungsten and macromolecular material to make of environment protecting.
Background technology
At present, the bullet that uses in military affairs or sports is mainly plumb, and the problem of using plumb to exist is: bullet is exposed to the field easily to environment, and harm humans is healthy.
Summary of the invention
The purpose of this invention is to provide a kind of use safely, have a composite balls of utilizing tungsten and macromolecular material to make of environment protecting.
Technical scheme of the present invention is: a kind of composite balls of utilizing tungsten and macromolecular material to make is characterized in that being comprised of the raw material of following weight portion: (1) tungsten powder 90-95 part; (2) mixture of stainless steel powder, copper powder and glass putty amounts to 2-3 part; (3) Hytrl Du Pont and the common 3-4 weight portion of Nordel Du Pont's mixture.
Preferably (1) tungsten powder is 93.91 parts; (2) mixture of stainless steel powder, copper powder and glass putty amounts to 2.41 parts; (3) Hytrl Du Pont and Nordel Du Pont mixture totally 3.68 weight portions.
Utilize the manufacture method of the composite balls that tungsten and macromolecular material make, it is characterized in that comprising the following steps:
(1) make in proportion mixture and Du Pont's mixture of tungsten powder, stainless steel powder, copper powder and glass putty;
(2) mixing: that step (1) Raw vertical mixer 250C degree heating 30 minutes, is mixed to get even feeding;
(3) injection moulding: feeding is heated to make it to have mobility, then feeding is injected die cavity and cool down and obtain the base substrate with certain rigidity of required form, then it is taken out from mould and obtain the base that is shaped;
(4) grind: with the shape base of step (3) be ground to tolerance+/-0.05mm;
(5) cleaning polishing: the shape base in step (4) through high temperature washing oven dry and polishing, is formed finished product.
Effect of the present invention is: a kind of composite balls of utilizing tungsten and macromolecular material to make is comprised of the raw material of following weight portion: (1) tungsten powder 90-95 part; (2) mixture of stainless steel powder, copper powder and glass putty amounts to 2-3 part; (3) Hytrl Du Pont and the common 3-4 weight portion of Nordel Du Pont's mixture.
Composite balls of the present invention can reach plumbous density 11g/cc and toughness, and is nontoxic product, and bullet is exposed to the field can not reduce the impact on human health to environment yet, has improved the security of using.
The present invention is described further below in conjunction with not limiting embodiment.
