Material for toilet lid and toilet seat and preparation method thereof

Abstract

The invention relates to a material for a toilet lid and a toilet seat and a preparation method thereof. The material consists of the following components in parts by weight: 30-75 parts of PA (polyamide), 5-20 parts of PP (polypropylene), 20-50 parts of flame retardant filler, 0.01-2 parts of antibacterial agent and 0.01-2 parts of other assistants. The preparation method comprises the following steps: firstly, placing the flame retardant filler and various assistants into a temperature-controllable high-speed stirrer, and stirring at high speed at the temperature of 90-110 DEG C for 2-10 minutes; then, adding PA and PP resin, and continuously stirring for 2-10 minutes; mixing the mixed components in a single-screw or twin-screw extruder at the temperature which is high enough to keep the selected PA in a molten state to obtain a polymerization product; and finally, extruding the obtained polymer in a stripped way, and then cutting the polymer into segments to form particles. Compared with the prior art, a product made of the material provided by the invention has the advantages of bright surface, scratch resistance, excellent flame retardance and good antibiotic property.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a material used for toilet lids and gaskets and a preparation method thereof. Background technique [0002] Mr. Jack, the founder of the World Toilet Organization, believes that "toilets are the measure of human civilization". With the development of human civilization history, going to the toilet has gone from outdoors to indoors, from squatting to sitting. The toilet, as one of the greatest inventions in the 19th century, once brought great convenience to people's lives, especially for women, pregnant women, obese, elderly, sick and weak. But toilet lids and gaskets have very small microbes that we can't see with our naked eyes. According to the investigation of relevant public health authorities, 32% of toilet lids and toilet gaskets have Shigella. Places with such serious pollution are in the most "intimate" contact with people's skin, so we must focus on cleaning. We often w...

Problems solved by technology

Acrylic has the characteristics of good toughness, not easy to break, easy to clean and soft texture. However, the surface hardness of acrylic board is low, easy to be scratched, and its cold resistance is also poor. The embrittlement temperature is about 9.2°C, and it is easy to burn. The index is only 17.3

ABS has high hardness, scratch resistance and is not easy to deform, but it is easy to change color, easy to break, poor aging resistance, poor high temperature resistance, and poor corrosion resistance

PP material is not easy to change color and break, has good high temperature resistance, strong corrosion resistance, and good water resistance, but the hardness is not enough and the production is difficult

Although there is also scratch-resistant PP at present, because the scratch-resistant agent is easy to precipitate, the finished product has a strong smell
