Abstract
The invention discloses a degradable plastic, which relates to the technical field of plastic raw materials and plastic products. The degradable plastic comprises the following raw material components: PP resin, plant fiber starch, a plasticizer, titanium dioxide, a lubricating agent and a heat stabilizer. The degradable plastic can biologically degrade in natural environment and belongs to a green and environmentally-friendly product. The product has excellent finish, an attractive appearance, high strength, high toughness, mild touch feel, comfortable use and free color setting and can be made into toothbrushes, combs, shoe cleaners, shavers, soap boxes, sewing boxes and the like. In addition, when the degradable plastic is made into a product, the hot melting temperature is only 120 to 140 DEGC which is much lower than the hot melting temperature of 200 to 220 DEG C of common plastic. And the degradable plastic has a significant energy-saving, power-saving and consumption-reducing use value for production.
Description
Technical field
The present invention relates to plastic raw materials and product technique field.
Background technology
Development along with petroleum industry, a large amount of plastics be present in we the life, work in, toothbrush as present production and sales all is to be made by the PP resin, along with human consumer house, travelling, the phenomenon that waste and old toothbrush is abandoned in the whole world is extremely serious, only consumes the common plastics amount China's toothbrush year and reaches few hundred thousand tonnes of, and, it can't recycling, the weathering of all can not degrading in 20 years to 30 years, and the visible environmental protection pressure that forms is very big.
Summary of the invention
The object of the invention is to invent a kind of degredation plastic raw material, is used for people's life, work with these plastics of making, to reduce environmental pollution.
The present invention includes following raw material forms: PP resin, made from plant fiber starch, softening agent, titanium dioxide, lubricant, thermo-stabilizer.
Wherein, described PP resin, made from plant fiber starch, softening agent, titanium dioxide, lubricant, thermo-stabilizer account for 30～35%, 54～60%, 2～10%, 1.5～2%, 0.5～1%, 0.5～1% of raw material total mass respectively.
The present invention is biodegradable under physical environment, belong to the environmental protection goods, product glossiness is good, and is attractive in appearance, intensity is high, good toughness, sense of touch is gentle, use is comfortable, can be configured to random color, can be made into toothbrush, comb, shoe polisher, shaver, soap box, workbox etc.In addition, the present invention is when making finished product, and its hot melting temperature only needs 120～140 ℃, and 200～220 ℃ of more common plastic hot melt temperature are much lower, has the using value of energy-conservation greatly, power saving, consumption reduction for production.
Also comprise 0.1% poly(lactic acid) in the raw material of the present invention.Can further improve the toughness and the intensity of product.
Softening agent of the present invention is any one in glycerine triacetate and glycerine or urea or the methane amide, and described glycerine triacetate accounts for 1～5% of raw material total mass, and any one in described glycerine or urea or the methane amide accounts for 1～5% of raw material total mass.
Lubricant of the present invention is a stearic acid.
Thermo-stabilizer of the present invention is a triphenyl phosphite.
Embodiment
Earlier clean vegetable fibre (stalk or discarded plant branch or leaf) is made starch.
Take by weighing PP resin 30～35kg, made from plant fiber starch (stalk or discarded plant branch or leaf) 54～60kg, softening agent glycerine triacetate 1～5kg, softening agent (any one in glycerine or urea or the methane amide) 1～5kg, titanium dioxide 1.5～2kg, lubricant stearic acid 0.5～1kg, thermo-stabilizer triphenyl phosphite 0.5～1kg, poly(lactic acid) 0.1kg respectively.
Above each raw material is mixed, through hot melt, extrude pellet by forcing machine again, degradable plastics particle promptly of the present invention.
Use example:
Be used to make handle: above degradable plastics particle is heated to 120～140 ℃, form feed liquid, feed liquid is annotated in the handle mould, again through cooling, handle is taken out in the demoulding, plants bristle again on handle, can form toothbrush.
Toothbrush finished product smooth finish is good, attractive in appearance, intensity is high, good toughness, sense of touch is gentle, use is comfortable.
Degraded test: adopting by reference QBT/T 2461-1999 " packaging degrading polyethylene film " the standard test of degrading.The result: the quality rate of weight loss is 14.6% (standard is 〉=10%) after the biological degradation.
Claims (4)
1. a degradable plastics is characterized in that comprising following raw material composition: PP resin, made from plant fiber starch, softening agent, titanium dioxide, lubricant, thermo-stabilizer; Described PP resin, made from plant fiber starch, softening agent, titanium dioxide, lubricant, thermo-stabilizer account for 30～35%, 54～60%, 2～10%, 1.5～2%, 0.5～1%, 0.5～1% of raw material total mass respectively; Described softening agent is any one in glycerine triacetate and glycerine or urea or the methane amide, and described glycerine triacetate accounts for 1～5% of raw material total mass, and any one in described glycerine or urea or the methane amide accounts for 1～5% of raw material total mass.
2. according to the described degradable plastics of claim 1, it is characterized in that also comprising in the described raw material 0.1% poly(lactic acid).
