The present invention relates to a kind of durable chopping block plastics, the raw material including following parts by weight: 90-110 parts of polypropylene, 4-6 parts of low density polyethylene (LDPE), 3-5 parts of glycerol, 4-7 parts of sorbierite, 2-4 parts of vinyltriethoxysilane, 2-4 parts of basic zirconium phosphate, 3-6 parts of ceramic fibre, 3-6 parts of nanometer calcium carbonate, 2-5 parts of asbestos, 3-6 parts of bentonite, 10-16 parts of antibacterial agent, 1-3 parts of fire retardant, 1-3 parts of potassium sorbate.The plastics select polypropylene plastics to be made, and light weight, intensity are high, do not absorb water, excellent in mechanical performance.By the way that magnesium hydroxide is added as fire retardant, plastics inflammable disadvantage in use is prevented；By the way that the antibacterial agent of nano phase ag_2 o, nano zeolite, nano-titanium dioxide composition is added, play the role of inhibition or kills bacterium, the pollution for breeding bacterium to food is avoided, therefore, which is highly suitable for production chopping block, and durable.
Description
Technical field
The present invention relates to plastics and preparation method thereof, and in particular to a kind of durable chopping block plastics and preparation method thereof.
Background technique
Chopping block is a kind of indispensable daily necessity of the occasions such as family, hotel, restaurant.The chopping block used now is largely
Made of timber, their density are high, toughness is strong, use securely, and still, there are many chopping block type as made of timber,
Be not easy to select, and some wood chopping blocks (such as poplar) due to wooden than more loose, hardness is inadequate, easy to crack, and surface is easy
Tool marks are generated, if cleaning is not thorough, it is easy to shelter evil people and countenance evil practices, breed bacterium, contaminated food.Moreover, because wood chopping block its
Surface can not print any pattern, and wood chopping block appearance is very dull and unchanged, thus can not attract consumer's sight
Attention.Most of all, being widely used for wood chopping block must just cut down a large amount of trees, certain break is caused to ecological environment
It is bad.
Currently, with plastic products development it is increasingly mature, light weight, intensity are high, durable, environmentally friendly, easy to carry
Plastic chopping block start the sight for gradually attracting consumer.Therefore it provides a kind of plastics of superior performance are used to prepare chopping block change
It obtains particularly significant.
Summary of the invention
It is an object of the invention to: a kind of durable chopping block plastics and preparation method thereof are provided.
To achieve the goals above, the invention provides the following technical scheme:
A kind of durable chopping block plastics, the raw material including following parts by weight:
90-110 parts of polypropylene, 4-6 parts of low density polyethylene (LDPE), 3-5 parts of glycerol, 4-7 parts of sorbierite, vinyl triethoxyl
2-4 parts of silane, 3-6 parts of ceramic fibre, 3-6 parts of nanometer calcium carbonate, 2-5 parts of asbestos, 3-6 parts of bentonite, resists 2-4 parts of basic zirconium phosphate
10-16 parts of microbial inoculum, 1-3 parts of fire retardant, 1-3 parts of potassium sorbate.
Preferably, a kind of durable chopping block plastics, the raw material including following parts by weight:
102 parts of polypropylene, 5 parts of low density polyethylene (LDPE), 4 parts of glycerol, 5 parts of sorbierite, 3 parts of vinyltriethoxysilane,
3 parts of basic zirconium phosphate, 4 parts of ceramic fibre, 5 parts of nanometer calcium carbonate, 3 parts of asbestos, 5 parts of bentonite, 12 parts of antibacterial agent, 2 parts of fire retardant, mountain
2 parts of potassium sorbate.
Preferably, the antibacterial agent is the mixture of nano phase ag_2 o, nano zeolite, nano-titanium dioxide.
Preferably, nano phase ag_2 o in the antibacterial agent, nano zeolite, nano-titanium dioxide mass ratio be 1:(3-
5):(2-4)。
Preferably, nano phase ag_2 o in the antibacterial agent, nano zeolite, nano-titanium dioxide mass ratio be 1:4:3.
Preferably, the fire retardant is magnesium hydroxide.
A kind of preparation method of durable chopping block plastics, weighs each raw material according to the ratio, mixing, and melting mixing, extrusion are made
Grain.
The beneficial effects of the present invention are:
Plastics of the present invention select polypropylene plastics to be made, and light weight, intensity are high, do not absorb water, excellent in mechanical performance.By adding
Enter magnesium hydroxide as fire retardant, prevents plastics inflammable disadvantage in use, improve the safety of plastics.By adding
The antibacterial agent for entering nano phase ag_2 o, nano zeolite, nano-titanium dioxide composition plays the role of inhibition or kills bacterium, avoids
Pollution of the bacterium to food is bred, therefore, which is highly suitable for production chopping block, and durable.
