Abstract
An antibacterial antimildew foam polyothylene plastics is prepared from polyethylene rsin, butane, monoglyceride, talk powder and antibacterial and antimildew mother particles through direct extruding out and foaming. Its advantages are high performance and low cost.
Description
Affiliated technical field
The present invention relates to polyethylene foams, particularly antibacterial moldproof polyethylene foam plastic adopts direct extrusion foaming preparation to have the manufacture method of the uncrosslinked highly foaming polyethylene sheet material of antibacterial and mouldproof performance.The highly foaming polyethylene extrusion sheet is a kind of uncrosslinked polyethylene foams, its production technique advanced person, and product performance are good, and the cost performance height is widely used as wrapping material and floor mat material.
Background technology
Along with people life enhancing along with the improving constantly of people's living standard, health perception, people also more and more pay attention to the comfortableness of living environment and sanitary condition, create life, study and the Working environment of comfortable, clean, antibiotic, mildew-resistant, the propagation that wards off disease and are the growing pursuits of people.Regrettably, follow people for own when building a living environment cool in summer and warm in winter, also for the breeding of microorganism, grow and created advantageous conditions.
Bacterium and mould are two kinds of main types of microorganism, have characteristics such as of a great variety, that distributed pole is wide, vitality is vigorous, when envrionment conditions is a relative humidity greater than 65%, when temperature 20-30 ℃, pH value 3.0-6.0, the nutritive substance on absorbing material surface and growing rapidly causes going mouldy and destroying of material.The mycelium that forms during mould-growth is a conductor, can make the decreasing insulating of material, and changes in weight the material peeling phenomenon can occur when serious.The metabolite that forms during mould-growth contains organic acid and toxin, can make phenomenons such as goods surfaces of tacky, variable color occur, become fragile, smooth finish reduction, and the people of long-term these mould curd products of contact is gone down with.Therefore, growth and the breeding of control and elimination unwanted bacteria, mould, the protection human health is the major subjects of current sciemtifec and technical sphere, and receives publicity day by day.
As the relevant prior art that contains the resin combination manufacture method of antibacterial mildew inhibitor, CN1294145A is for example arranged, it adopts polyolefin resin, inorganic antiseptic and organic mould inhibitor to prepare the antibacterial and mouldproof masterbatch.
Summary of the invention
The purpose of this invention is to provide a kind of antibacterial moldproof polyethylene foam plastic, system adopts the resin combination among the CN1294145A to join in the polyethylene raw material as anti-bacterium mildewproof additive, by changing processing parameter, preparation has antibacterial and mouldproof performance and highly foaming polyethylene extrusion sheet, it is a closed pore formula foamy structure, has the antibacterial and mouldproof performance, this section bar is to utilize forcing machine that the direct extrusion foaming typing of raw material is prepared, the highly foaming polyethylene extrusion sheet is a kind of uncrosslinked polyethylene foams, its production technique advanced person, product performance are good, and the cost performance height is widely used as wrapping material and floor mat material.
