Abstract
The invention discloses a plastic product, particularly relates to a formula and a manufacturing process of a degradable plastic bag, and aims to provide a formula and a manufacturing process of a degradable plastic bag with medium thickness, high tensile strength, simple production technology and adjustable degradation time. The degradable plastic bag is prepared from the following components in percentage by weight: 65-80% of calcium carbonate powder, 1-3% of inorganic powder, 1-3% of high filling powder and 14-35% of polyvinyl, wherein the calcium carbonate powder comprises the following components in percentage by weight: 80% of calcium carbonate particles, 15% of toughness particles, 2% of a foam killing agent and 3% of filling particles. The prepared degradable plastic bag has the advantages of capability of being degraded, high-temperature resistance, flame proof, tastelessness, safety, sanitariness and the like; the degradation time of the bag can be adjusted according to the ratio of calcium carbonate powder to polyvinyl, and the higher the polyvinyl content is, the longer the degradation time is; compared with a traditional plastic package, the prepared degradable plastic bag has the advantage that the longest degradation time is 120 hours.
Description
Technical field
The present invention relates to a kind of plastics, especially a kind of formula of degradable plastic pocket and manufacturing process.
Background technology
Plastics bag is article very common during we live, the birth of plastics bag brings great convenience to people's life, but As time goes on, existing its nondecomposable characteristic had of plastics bag has caused very serious environmental problem to us, therefore, research and production degredation plastic bag are subject to very large attention in the world.
At present, domestic reaching has indivedual advanced enterprises to work out the degredation plastic bag in the world, but due to its complex manufacturing, production cost is high, the thickness of product and tensile strength can't reach reinforcement, thereby are difficult to be promoted effectively on market, make its application cause very large restriction.
Summary of the invention
The objective of the invention is in order to solve the deficiency of above-mentioned technology, and provide a kind of thickness moderate, tensile strength is large, and production technique is simple, formula and the manufacturing process of the adjustable degradable plastic pocket of degradation time.
In order to achieve the above object, the formula of a kind of degradable plastic pocket that the present invention is designed, it comprises 65-80% Paris white, 1-3% inorganic powder, the high powder filler of 1-3% and 14-35% polyethylene; Wherein Paris white is comprised of 80% calcium carbonate granule, 15% toughness particle, 2% defoamer and 3% filler particles.
Production technique: the first step is dosed to Paris white, inorganic powder, high weighting material and polyethylene in stirrer and stirs 3-5min by its proportioning; Second step, add in inflation film manufacturing machine, heats to 190-210 ℃, blows out material membrane after 40min; The 3rd step, cooling, flanging; The 4th step, add in bag machine, obtains the plastics bag of required model.
The resulting degradable plastic pocket of the present invention, have can degrade, the advantage such as high temperature resistant, anti-flaming, tasteless, safety and sanitation; Its degradation time is regulated according to the ratio between Paris white and polyethylene, and wherein polymerized ethylene content is higher, and the degradable time is longer; The plastic prod that adopts this method to make is compared with the conventional plastic packing, and its time of degrading the soonest is 120 hours.
