Abstract

The invention provides a plastic floor substrate and a making method thereof. The plastic floor substrate comprises, by weight, 80-90 parts of polyvinyl chloride, 20-30 parts of dioctyl phthalate, 60-80 parts of calcium carbonate, 6-12 parts of titanium dioxide, 2-6 parts of epoxy soybean oil, 1-5 parts of magnesium stearate, 2-5 parts of phosphate, 12-18 parts of a plasticizer DPO, 0.5-2 parts of polyvinyl alcohol, 0.3-0.7 parts of chitin, 0.5-1 part of nano-ZnO powder, and 0.5-1 part of nano-Ag powder. The plastic floor substrate has good performances in antibiotic tests, and has an Escherichia coli inhibition rate of above 99.7% during the 24th month in long-term tests, and a Staphylococcus aureus inhibition rate of above 99.6%.

Description

technical field [0001] The invention belongs to the field of interior decoration materials, in particular to a plastic floor base material and a preparation method thereof. Background technique [0002] At present, PVC flooring is a new type of light-weight floor decoration material that is very popular in the world today, also known as "light-weight floor material". It is a popular product in Europe, America and Asia. Plastic flooring has entered the Chinese market since the 1980s, and has been widely recognized in domestic large and medium-sized cities, and is widely used, such as indoor homes, hospitals, schools, office buildings, factories, public places, supermarkets, businesses, sports venues, etc. PVC floor can be divided into block material (floor tile) and roll material (floor leather) according to its use state. Its main advantage is that it is light in weight, 10 times lighter than wooden floors and 20 times lighter than ceramic tiles, and it is easy to carry; du...
