Abstract
The invention discloses a rat and termite preventing PET (polyethylene terephthalate)/PC (polycarbonate) environment-friendly plastic. The environment-friendly plastic comprises the following components in parts by weight: 30 parts of PET, 60 parts of PC, 4-8 parts of compatilizer SEBS-g-MAH and 3-5 parts of biological rat and a termite preventing agent. The rat and termite preventing PET/PC environment-friendly plastic has better low temperature resistance, strong impact and high thermal deformation temperature and has excellent property of preventing damages caused by termites and rats.
Description
Technical field
The present invention relates to a kind of plastic material, relate in particular to a kind of rat-and-ant proof PET/PC environmentally-friendly plastic.
Background technology
Mouse extensively lives in each area in the world as a kind of reproductivity and the very strong rodent of vitality, because its front tooth is very flourishing and constantly growth, so muroid has the object of nibbling to keep the habit that its tooth is sharp, the distinctive smell of plastics makes plastics become the muroid object that often bites.
Termite also claims that worm is luxuriant, is in the streets commonly called as flood ant (because conventionally occur, hence obtaining one's name) before raining, the general name of isoptera insect, approximately kind more than 2000.For the paurometabola of incomplete metamorphosis and be social insect, the termite individuality in each termitarium can reach more than 1,000,000.Termite damage building construction, reservoir dam, mountain forest orchard, vehicle ship etc., cause very large loss to national economy.The distinctive smell of plastics makes plastics become the termite object that often bites.
Existing plastic material in order to realize rat-and-ant proof, adds the poisoning agents such as Niran, aldrin conventionally in plastics, has very large environmental pollution, and very harmful to HUMAN HEALTH, not environmental protection of the utmost point.
Summary of the invention
For above shortcomings in prior art, technical problem to be solved by this invention is to provide a kind of rat-and-ant proof PET/PC environmentally-friendly plastic.
Technical problem to be solved by this invention is achieved by the following technical solution:
A rat-and-ant proof PET/PC environmentally-friendly plastic, consists of by weight following component: 30 parts of PET, 60 parts of PC, 4-8 part compatilizer SEBS-g-MAH, the biological rat-and-ant proof agent of 3-5 part.
Described biological rat-and-ant proof agent, consists of by weight following component: 5-15 part 11,12,13,14-tetra-dehydrogenation matridinde-15-ketone, 5-15 part Triptonide, 5-15 part N-(4-hydroxyl-3-methoxybenzy)-8-methyl pelargonamide.
11,12,13,14-, tetra-dehydrogenation matridinde-15-ketone, Triptonide, N-(4-hydroxyl-3-methoxybenzy)-8-methyl pelargonamide are uniformly mixed, and can make biological rat-and-ant proof agent.
Can adopt industry universal method to be prepared rat-and-ant proof PET/PC environmentally-friendly plastic of the present invention, for example: by proportioning, take each component, after mixing, melting mixing, extruding pelletization, obtain described rat-and-ant proof PET/PC environmentally-friendly plastic.
Concrete, can be for take each component by proportioning, in mixing machine, under room temperature, control rotating speed at 300-400 rev/min, mix 2-10 minute, after taking-up, proceed in screw extrusion press, extruding pelletization at 240-260 ℃ of temperature, obtains described rat-and-ant proof PET/PC environmentally-friendly plastic.
PC, polycarbonate, water white transparency, heat-resisting, shock resistance, fire-retardant BI level has good mechanical property in common use temperature.With performance, approach polymethylmethacrylate and compare, the impact resistance of polycarbonate is good, and specific refractory power is high, and good processability does not need additive just to have UL94V-0 level flame retardant properties.PET, poly terephthalic acid class plastics, have good abrasion performance frictional property and dimensional stability and electrical insulating property.
Rat-and-ant proof PET/PC environmentally-friendly plastic of the present invention, has good resistance to low temperature, impacts strong and heat-drawn wire is high, and have excellent preventing from being eaten by ant and mouse performance.
Embodiment
Embodiment 1
According to corresponding embodiment 1-4 data in table 1, take each raw material.Each component is joined in high-speed mixer, control rotating speed at 320 revs/min under room temperature, mix 8 minutes, proceed in screw extrusion press after taking-up, extruding pelletization at 250 ℃ of temperature, obtains rat-and-ant proof PET/PC environmentally-friendly plastic.
