Problems solved by technology

At present, the antibacterial agent widely used in antibacterial plastic particles for toys in China is silver-based antibacterial agent. Although its bactericidal performance is high, it is easy to change color when exposed to light or stored, and it is not good for the human body to separate out from the plastic.

Embodiment 1

[0022] Embodiment 1, carry out as follows: 1, by weight 1 part of AgNO3, 20 parts of Zn(NO3)2 and 35 parts of ZnSO4 use deionized water to configure respectively 2.5% AgNO3 solution, 10% saturation 2. Add 100 parts of zeolite to the above-mentioned AgNO3 solution, stir at a low speed to form a uniform slurry, heat to 80°C-boiling, and keep stirring at this temperature for 60 minutes, stop Stir and cool to room temperature. After the slurry is precipitated and layered, pour off the supernatant, then add the above-mentioned Zn(NO3)2 and ZnSO4 solution to the precipitated layer, stir at a low speed to form a uniform slurry, heat to 70°C, and react for 200 minutes; 3. Add 0.35 parts of dispersant (CA-977) to the above slurry, stir evenly, stop heating, wait for the system to cool down, dry the slurry, and crush the solid powder with a particle size of less than 30μ; 4. In the powder obtained in the previous step Add 25 parts of ZnO powder, then add 10 parts of coagent (borax), and...

Embodiment 2

[0023] Embodiment 2, carry out according to the following steps: 1, the AgNO of 0.3 parts by weight , the Zn of 35 parts (NO ) 2 and the ZnSO of 40 parts configure the AgNO of 1% with deionized water respectively Solution, 10% saturation 2. Add 100 parts of zeolite to the above AgNO3 solution, stir at a low speed to form a uniform slurry, heat it to 80°C-boiling, and keep stirring at this temperature for 20-80 minutes , stop stirring and cool down at room temperature. After the slurry is precipitated and layered, pour off the supernatant, then add the above-mentioned Zn(NO3)2 and ZnSO4 solution to the precipitated layer, stir at a low speed to form a uniform slurry, and then heat it to 60-90°C. React for 60-300 minutes; 3. Add 0.16 parts of dispersant (HYDROPALAT) to the above slurry, stir evenly, stop heating, wait for the system to cool down, dry the slurry, and crush the solid powder with a particle size of less than 30μ; 4. In the previous step Add 35 parts of ZnO powder i...

Abstract

The invention relates to antibacterial and luminous plastic particles for a toy and a preparation method for the plastic particles. The plastic particles are characterized by mainly comprising the following components: polyvinyl chloride (PVC), an antibacterial master batch, a plasticizer, a stabilizer, rare-earth long-acting fluorescent powder and a coupling agent in a weight part ratio of 100:(1-8):(1-80):(0.1-6):(0.5-6):(1-4). The reproduction of microorganisms on the surface of the prepared plastic toy can be inhibited, the sterilization range is wide, the killing rate of bacteria and molds which are adhered to the surface of the toy is over 95 percent, and the aim of using the toy hygienically and safely is fulfilled. The product has the characteristic that the product is luminous, and the playing interest of children is enhanced.

Description

1. Technical field [0001] The invention relates to a plastic particle, in particular to an antibacterial luminous plastic particle for toys and a manufacturing method thereof. 2. Background technology [0002] With the progress of society and the continuous improvement of living standards, children's requirements for toys are also further improved, and toys are required to be constantly novel and beautiful. According to domestic surveys: toys are children's closest companions, and children under the age of 6 spend 15,000 hours with toys, and toys have therefore become a major hidden danger to children's health. After the toy is played by children for 24 hours, there are an average of 35 bacterial communities per square centimeter on the surface of the toy, even including pathogens of Shigella, Salmonella typhi, influenza virus, hepatitis B virus and other infectious diseases. At present, the antibacterial agent widely used in antibacterial plastic particles for toys in Chin...
