Problems solved by technology

Because the method of directly using antibacterial materials will affect the appearance of plastic products and lead to a decrease in antibacterial efficiency, and the processing cost of using antibacterial plastics is relatively high. At present, the processing method of plastic products widely used in the world is to add antibacterial masterbatches. Antibacterial plastic products

Embodiment 1

[0079] An antibacterial plastic sheet-like cutting board is made of the following raw materials in percentage by weight:

[0080] The composition ratio of the present invention is:

[0081]

[0082] The proportion of intermediate product functional masterbatch is as follows

[0083]

[0084] The proportion of the intermediate product antibacterial masterbatch is as follows:

[0085]

specific Embodiment approach

[0087] A kind of preparation method steps of antibacterial non-slip plastic sheet cutting board is as follows:

[0088] A. Add inorganic fillers such as calcium carbonate, talcum powder, lithopone, and polyethylene low-molecular wax directly into the polypropylene polymer material resin 1, mix through a high-speed mixer 2, and put the mixture into the twin-screw extrusion after initial mixing Machine melt mixing 3;

[0089] The process is as follows: first pour the above-mentioned raw materials mixed in proportion into the mixing chamber of the high-speed mixer, first run at low speed for 30 seconds and then switch to high-speed rotation, when the temperature of the material rises to 70 degrees, the mixing is completed, and after the material is slightly cooled, it will be rotated under the action of the impeller Discharged from the discharge port;

[0090] After the temperature reaches the requirement, pour the mixture into the hopper of the twin-screw extruder, turn on the ...

Abstract

The invention discloses an antibacterial plastic sheet cutting board and a preparation method thereof. The cutting board is prepared by functional master batch, polypropylene high molecular material and antibacterial master batch according to a certain proportion. The method comprises the following steps: firstly inorganic filling calcium carbonate, French chalk, lithopone and polyethylene low molecular wax are directly added into polypropylene high molecular material resin, mixed in a mixer and granulated; secondly inorganic silicate antibacterial agent and the polyethylene low molecular wax are added directly in the polypropylene high molecular material resin, mixed and granulated; thirdly the functional master batch, polypropylene high molecular material and inorganic silicate antibacterial master batch containing silver ions are mixed according to proportion; fourthly the mixture is poured into a plastic injection machine provided with the cutting board, heated, stirred, dissolved, molded, formed and cooled; and fifthly the prepared antibacterial master batch and the thermoplastic rubber are stirred, placed in a mold and formed so as to obtain antibacterial and antisliding cutting board. The method is easy to be carried out, has simple operation, strong practicability and good antisliding and antibacterial effect.

Description

technical field [0001] The present invention relates to a kind of kitchen article, more specifically relate to a kind of antibacterial non-slip plastic sheet (inorganic antibacterial plate shape, plastic chopping board) cutting board that adds inorganic silver ions in the sheet cutting board body, the present invention also relates to a kind of The invention discloses a preparation method for making an antibacterial and non-slip cutting board. Background technique [0002] Cutting boards are indispensable kitchen utensils in people's lives. In the past, cutting boards were mostly made of wood, which has the advantages of durability, but the disadvantages are bulky, difficult to clean, and difficult to place. They are gradually replaced by plastic cutting boards. Our commonly used plastic cutting boards are not temperature-resistant due to technological reasons, and are easily deformed when exposed to heat. As we all know, bacteria are most likely to hide in places with mois...
