Description

Rat-and-ant proof PET/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 PET/PC environmentally-friendly plastic.

Background technology

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

Coptotermes formosanus Shtrari. is luxuriant 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 very big loss to national economy. The distinctive abnormal smells from the patient of plastics makes plastics become Coptotermes formosanus Shtrari. often to bite object.

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

Summary of the invention

For above shortcomings in prior art, the technical problem to be solved is to provide a kind of rat-and-ant proof PET/PC environmentally-friendly plastic.

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

A kind of rat-and-ant proof PET/PC environmentally-friendly plastic, is made up of by weight following component: 30 parts of PET, 60 parts of PC, 4-8 part compatilizer SEBS-g-MAH, 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-dehydrogenation 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-hydroxyl-3-methoxybenzy)-8-methyl pelargonamide are uniformly mixed, and can be prepared by biological rat-and-ant proof agent.

Industry universal method can be adopted to be prepared the rat-and-ant proof PET/PC environmentally-friendly plastic of the present invention, for instance: weigh each component by proportioning, after mix homogeneously, melting mixing, extruding pelletization, namely obtain described rat-and-ant proof PET/PC environmentally-friendly plastic.

Concrete, it is possible to for weighing each component by proportioning, in mixer, control rotating speed under room temperature at 300-400 rev/min, mix 2-10 minute, proceed to after taking-up in screw extruder, extruding pelletization at 240-260 DEG C of temperature, namely obtains described rat-and-ant proof PET/PC environmentally-friendly plastic.

PC, Merlon, water white transparency, heat-resisting, shock resistance, fire-retardant BI level, in commonly used temperature, there is good mechanical performance. Comparing close to polymethyl methacrylate with performance, the impact resistance of Merlon is good, and refractive index is high, good processability, it is not necessary to additive just has UL94V-0 level fire resistance. PET, poly terephthalic acid class plastics, there is excellent abrasion performance frictional property and dimensional stability and electrical insulating property.

The rat-and-ant proof PET/PC environmentally-friendly plastic of the present invention, has good resistance to low temperature, impacts strong and heat distortion temperature height, and have the preventing from being eaten by ant and mouse performance of excellence.

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 in high-speed mixer, controls rotating speed under room temperature at 320 revs/min, mix 8 minutes, proceed to after taking-up in screw extruder, extruding pelletization at 250 DEG C of temperature, it is thus achieved that rat-and-ant proof PET/PC environmentally-friendly plastic.
