Abstract
A photodegradable thermal insulation plastic belongs to the technical field of decorative plastic material, and is composed of the following components: 100-120 parts of polyurethane foaming plastic, 1-3 parts of a foaming agent, 3-5 parts of a plasticizer, 1-3 parts of a fire retardant, 1-2 parts of an anti-oxidant, 1-2 parts of flexibilizer, 0.5-1 part of a dispersant and 5-9 parts of a photosensitizer. The components of the plastic is easily available and cheap; and the plastic can be degraded by using light sensitivity of nano titanium dioxide, and the photodegraded residues do not influence the environment.
Description
Technical field
The present invention relates to a kind of photodegradation insulating plastic pipe, belong to decorative plastic material technology field.
Background technology
Insulating plastic pipe refers generally to expanded plastic, comprise polystyrene foamed plastics, rigid urethane foam, polyethylene foams, phenolic foamed plastics, the cast-in-place foamed plastics of urea formaldehyde, wherein especially be widely used with the excellent properties of urethane foam.But along with the increase of the usage quantity of porous plastics, consequent environmental problem is also day by day serious, because porous plastics hard degradation under field conditions (factors), particularly white porous plastics, light due to its quality, volume is large, even be embedded in the underground, also being difficult in a century can degraded, therefore, can only burn or recycle, but can send pungent niff when burning, and can not burn thoroughly, therefore have the residue of black and can not reuse, burning method inadvisable; Recycled plastic needs certain cost, and if plastics itself adhere to material messy and that be not easy to remove after using, need to clean when reclaiming, this just needs a large amount of clean-out systems, cost is high, do not calculate.Therefore a lot of degradative plasticss have appearred in recent years, the degradative plastics that occurs at present is divided into photodegradable plastics, biodegradable plastic, Photo biodegradable plastics and water degradative plastics, wherein again with the low cost of photodegradable plastics, palliating degradation degree fully, characteristics such as environmental protection and enjoy attention.The photodegradable plastics that occurs in the market mostly is greatly the photodegradation polystyrene plastic, and the palliating degradation degree of this plastics is incomplete, thereby can stay some problems, so need a kind of brand-new photodegradation insulating plastic pipe to replace polystyrene foamed plastics.
Summary of the invention
In view of the defective that prior art exists, the purpose of this invention is to provide a kind of photodegradation fully, can not leave over the environment-friendly type photodegradation insulating plastic pipe of other environmental problems.
For achieving the above object, the technology used in the present invention solution is: a kind of photodegradation insulating plastic pipe, be comprised of polyurethane foam plastics, whipping agent, softening agent, fire retardant, oxidation inhibitor, toughner, dispersion agent, photosensitizers, wherein each component proportion is: 100 ~ 120 parts of urethane plastic, 1 ~ 3 part of whipping agent, 3 ~ 5 parts, softening agent, 1 ~ 3 part of fire retardant, 1 ~ 2 part, oxidation inhibitor, 1 ~ 2 part of toughner, 0.5 ~ 1 part of dispersion agent, 5 ~ 9 parts of photosensitizerss.
Described whipping agent is a kind of in sodium lauryl sulphate, polyoxyethylenated alcohol sodium sulfate.
Described softening agent is a kind of in Vanay, glycol ether benzoic ether.
Described fire retardant is selected ammonium polyphosphate, a kind of in triphenylphosphate.
Described oxidation inhibitor is at least a in pentanoic, Ursol D and dihydroquinoline.
Described toughner is at least a in liquid acrylonitrile butadiene rubber, polyvinyl butyral acetal, Vinyl Acetate Copolymer.
Described dispersion agent is at least a in methyl amyl alcohol, derivatived cellulose, polyacrylamide.
Described photosensitizers is nano titanium oxide, and particle diameter is 15 ~ 30nm.
In the present invention, the raw material of each component is easy to get, and low price, utilizes nano titanium oxide to the responsive of light and then makes plastic degradation, and the later residue of photodegradation can not impact environment.
