Description

Rat-and-ant proof ABS/PC environmentally-friendly plastic

Technical field

The present invention relates to a kind of plastic material, particularly relate to a kind of rat-and-ant proof ABS/PC environmentally-friendly plastic.

Background technology

Mouse as the rodent that a kind of reproductive capacity and vitality are the strongest extensively live in the world each Area, owing to its front tooth is the most flourishing and can constantly grow, so muroid has object of nibbling to be kept its tooth Sharp habit, the distinctive abnormal smells from the patient of plastics makes plastics become muroid often to bite object.

It is luxuriant that Coptotermes formosanus Shtrari. is also known as worm, is in the streets commonly called as flood ant (because generally occurring before raining, hence obtain one's name), The general name of isoptera insect, about kind more than 2000.For incomplete metamorphosis manometavola and be social insect, Coptotermes formosanus Shtrari. in each termitarium is individual up to more than million.Termite damage building construction, reservoir dam, Mountain forest orchard, vehicle ship etc., cause the biggest loss to national economy.The distinctive abnormal smells from the patient of plastics makes to mould Material becomes Coptotermes formosanus Shtrari. and often bites object.

Existing plastic material, in order to realize rat-and-ant proof, adds Niran, Emhorn the most in the plastic , there is the biggest environmental pollution in the poisoning agents such as agent, and very harmful to health, and pole is not environmentally.

Summary of the invention

For above-mentioned deficiency present in prior art, the technical problem to be solved is to provide one Plant rat-and-ant proof ABS/PC environmentally-friendly plastic.

The technical problem to be solved is achieved by the following technical solution:

A kind of rat-and-ant proof ABS/PC environmentally-friendly plastic, is made up of by weight following component: 70 parts of ABS, 25 parts of PC, 0.1-0.9 part politef, 3-5 part biology rat-and-ant proof agent.

Described biological rat-and-ant proof agent, is made up of by weight following component: 5-15 part 11,12,13,14-tetra-is gone Hydrogen matridinde-15-ketone, 5-15 part Tripterygium wilfordii lactone ketone, 5-15 part N-(4-hydroxyl-3-methoxybenzy)-8- Methyl pelargonamide.

11,12,13,14-tetra-dehydrogenation matridinde-15-ketone, Tripterygium wilfordii lactone ketone, N-(4-hydroxy-3-methoxy Benzyl)-8-methyl pelargonamide is uniformly mixed, and can be prepared by biological rat-and-ant proof agent.

Industry universal method can be used to be prepared the rat-and-ant proof ABS/PC environmentally-friendly plastic of the present invention, Such as: weigh each component by proportioning, after mix homogeneously, melting mixing, extruding pelletization, i.e. obtain described Rat-and-ant proof ABS/PC environmentally-friendly plastic.

Concrete, can be to weigh each component by proportioning, in mixer, control rotating speed under room temperature and exist 300-400 rev/min, mix 2-10 minute, proceed to after taking-up in screw extruder, at 240-260 DEG C At a temperature of extruding pelletization, i.e. obtain described rat-and-ant proof ABS/PC environmentally-friendly plastic.

PC, Merlon, water white transparency, heat-resisting, shock resistance, fire-retardant BI level, in commonly used temperature Inside there is good mechanical performance.With performance close to compared with polymethyl methacrylate, Merlon resistance to Impact property is good, and refractive index is high, good processability, it is not necessary to it is fire-retardant that additive just has UL94V-0 level Performance.(acrylonitrile-butadiene-styrene copolymer, ABS is Acrylonitrile Butadiene to ABS resin The acronym of Styrene) it is a kind of intensity height, good toughness, thermoplastics type's high score easily processed into type Sub-material structure.

The rat-and-ant proof ABS/PC environmentally-friendly plastic of the present invention, has preferable mouldability and mechanicalness, and has excellent Different preventing from being eaten by ant and mouse performance.

Detailed description of the invention

Embodiment 1

Each raw material is weighed according to embodiment 1-4 data corresponding in table 1.Each component is joined mixed at high speed In machine, under room temperature, control rotating speed is at 320 revs/min, mixes 8 minutes, proceeds to screw extruder after taking-up In, extruding pelletization at a temperature of 250 DEG C, it is thus achieved that rat-and-ant proof ABS/PC environmentally-friendly plastic.
