specific Embodiment

[0017] Specific embodiment: phosphate ester starch-vegetable glue copolymer film formula, its composition mainly comprises: 15 parts of disodium hydrogen phosphate, 100 parts of cornstarch, 100 parts of soybean protein, 5 parts of turpentine, 15 parts of 50% sodium hydroxide aqueous solution, lime 40 parts of water, 30 parts of water glass, 2 parts of thiourea, 1 part of carbon tetrachloride, 2 parts of pentachlorophenol, and 200 parts of water.

[0018] Phosphate starch-vegetable glue copolymer film preparation process specifically comprises the following steps:

[0019] Step 1: Put water and disodium hydrogen phosphate into the mixing tank according to the proportion, heat up to 60°C under constant stirring, so that the disodium hydrogen phosphate solution is completely dissolved, and fully mix the corn starch and disodium hydrogen phosphate solution according to the proportion Put it into the reactor, stir the material in the reactor and raise the temperature to 70-80°C. Wh...

Abstract

The invention provides a formula and a preparation method of a phosphate starch-vegetable gum copolymer film. The formula mainly comprises the following components: 15-20 parts of disodium hydrogen phosphate, 100-150 parts of corn starch, 100-120 parts of soybean protein, 5-7 parts of turpentine, 15-20 parts of 50% sodium hydroxide aqueous solution, 40-50 parts of lime water, 30-40 parts of sodium silicate, 2-5 parts of thiourea, 1-2 parts of carbon tetrachloride, 2-5 parts of pentachlorophenol and 200-220 parts of water. The target film product is obtained by carrying out mixing and adjusting, then carrying out extrusion with a twin-screw extruder, water cooling and cutting to obtain a double degradation masterbatch and finally carrying out film blowing with a film blowing machine. The formula and the preparation method have the beneficial effects that the adopted starch is rich in sources and low in cost and is environment-friendly; the prepared plastic film has high strength, is low in production cost, is biodegradable and can effectively relieve the problem of white pollution.

Description

Technical field: [0001] The invention relates to the technical field of plastic film production, in particular to a phosphate starch-vegetable gum copolymerized film and a preparation method thereof. Background technique: [0002] With the vigorous development of the plastic industry, the environmental pollution caused by waste plastic film garbage is becoming more and more serious, and white pollution has become a global environmental problem. Therefore, people must intensify their efforts to develop biodegradable plastic films to control the environmental pollution caused by plastic waste. [0003] Starch is a natural polymer material with abundant sources and low price. It is also an inexhaustible renewable resource. It can be biodegraded under various environmental conditions. The final degradation products carbon dioxide and water can It is recycled through photosynthesis of plants without causing any pollution to the environment. However, the starch molecular chain c...
