Problems solved by technology

The application uses a variety of additives to modify the polyvinyl chloride pipe. Although it can improve its performance to a certain extent, there are too many types of raw materials used, including various small molecules and macromolecular compounds. The defect of poor capacity limits the improvement of the performance of plastic hoses

Embodiment 1

[0047] Modified polyvinyl chloride is prepared by the following method:

[0048] S1. Add acryloyl chloride and acetone into the reactor, stir to dissolve and then add thiosalicylic acid and potassium carbonate. While stirring and heating up, nitrogen gas is introduced. When the temperature of the mixed solution reaches 48°C, it is protected under nitrogen at 48°C. Under the conditions of reaction for 12 hours, after the reaction was completed, the first extraction was carried out with ethanol, the crude product was vacuum-dried at 100°C for 2 hours, then poured into tetrahydrofuran, the pH value was adjusted to 4.0 with hydrochloric acid, and then extracted with ethanol for the second time. The product was then vacuum-dried at 100°C for 2 hours to obtain a modifier;

[0049] Wherein, the ratio of the consumption (mass) of acetone, acryloyl chloride, thiosalicylic acid, and potassium carbonate is 125:6:10:10;

[0050] S2. Add 10g of PVC, 0.04g of initiator (BPO), 80mL of 1,2-d...

Embodiment 2

[0052] Modified polyvinyl chloride is prepared by the following method:

[0053] S1. Add acryloyl chloride and acetone into the reactor, stir to dissolve and then add thiosalicylic acid and potassium carbonate. While stirring and heating up, nitrogen gas is introduced. When the temperature of the mixture reaches 50°C, it is protected under nitrogen at 50°C. Under the conditions of reaction for 10 hours, after the reaction is completed, the first extraction is carried out with ethanol, the crude product is vacuum-dried at 100°C for 3 hours, then poured into tetrahydrofuran, the pH value is adjusted to 4.5 with hydrochloric acid, and then extracted with ethanol for the second time. The product was then vacuum-dried at 100°C for 3 hours to obtain a modifier;

[0054] Wherein, the ratio of the consumption (mass) of acetone, acryloyl chloride, thiosalicylic acid, and potassium carbonate is 125:7:12:11;

[0055] S2. Add 10g of PVC, 0.05g of initiator (BPO), 90mL of 1,2-dichloroetha...

Embodiment 3

[0057] Described plasticizer is prepared by following method:

[0058] Add p-hydroxymethylbenzoic acid, epoxy fatty acid methyl ester, chloroform and N,N-dimethylformamide into the reactor according to a certain proportion, stir and mix evenly, and react at a constant temperature of 60°C for 5 hours. After the end, it was extracted with ethanol, and the product was vacuum-dried at 100°C for 2 hours to obtain a plasticizer;

[0059] Among them, the mass ratio of p-hydroxymethylbenzoic acid, chloroform, epoxy fatty acid methyl ester and N,N-dimethylformamide is 1:12:0.9:0.0001.

Abstract

The invention discloses a modified particle-based plastic hose for pouring. The modified particle-based plastic hose comprises the following raw materials in parts by weight: 90-100 parts of modifiedpolyvinyl chloride, 3-4 parts of a stabilizer, 12-15 parts of a plasticizer, 5-6 parts of nano calcium carbonate and 10-12 parts of nitrile rubber. The plastic hose is prepared by the following steps:1, mixing and granulating; 2, extrusion molding, and 3, printing, punching and hot stamping. According to the invention, modified polyvinyl chloride molecules are used as a polymer matrix, a benzenering and carboxyl are introduced to a PVC side chain, the benzene ring can improve the strength of PVC molecules, the carboxyl can improve the binding force of a plasticizer and a polymer matrix, theuse time effectiveness of the plasticizer is improved, uniform dispersion of nano calcium carbonate can be promoted through introduction of the carboxyl, the synergistic toughening effect on nitrile rubber is achieved, the strength of the obtained plastic hose is kept, meanwhile, the toughness is greatly improved, and the use requirements of the plastic hose in the field of agricultural irrigationcan be met.

Description

technical field [0001] The invention belongs to the field of plastic hose processing, and in particular relates to a plastic hose for pouring based on modified particles and a production process thereof. Background technique [0002] Because plastic hose has the advantages of corrosion resistance, no leakage, anti-scaling, long service life, etc., the market application volume and application fields are growing rapidly. At present, the consumer market of plastic hoses is mainly divided into four major application areas: daily consumption and health care, hydraulic transmission systems in industry, automobile manufacturing and maintenance, and water conservancy projects. Polyvinyl chloride plastic is an important polymer material that is widely used in many plastic pipes. It has excellent physical and chemical properties such as good flame retardancy, strong acid and alkali resistance, high structural strength, and good electrical insulation. It is widely used in agricultural...
