Description
Technical field
The present invention relates to chopping block, particularly to a kind of Combined chopping block and its forming method.
Background technology
Chopping block, also known as chopping board, is for beating, cutting, chop, pound pad implements down below during thing, according to the difference of material, can
It is divided into Wood chopping block, bamboo matter chopping block, Plastic chopping block and toughened glass chopping board etc., because Wood chopping block density is high, toughness is strong, make
Use very firm, and Wood chopping block be typically natural material, does not add other materials, has higher security performance,
It is widely used.
But because Wood chopping block species is various, it is difficult to select, some Wood chopping blocks such as Sapium sebiferum (L.) Roxb. wood contains noxious substance, and
There is abnormal flavour, pollution is produced to dish, easily cause vomiting, suffer from abdominal pain, dizzy symptom；Also has poplar chopping board, hardness is inadequate, Yi Kai
Split, surface easily produces tool marks, easily shelters evil people and countenance evil practices in tool marks, breed bacteria, contaminated food；And the big multimass of Wood chopping block
Larger, carrying inconvenience.Nowadays gradually gradually replaced by Plastic chopping block, Plastic chopping block is safe and nontoxic in use, have
Excellent intensity, can resistance to point device cutting for a long time.
At present, in existing patent, the Chinese patent for CN105400080A for the application publication number discloses a kind of damage resistant enhancing
PP plastics and its forming method, according to weight portion, including 90～110 parts of PP resin, 1～5 part of graphite, 1～5 part of calcium stearate,
