Problems solved by technology

Solve the use of general-purpose, cheap materials and their modified combinations to produce low-cost new varieties of products; the patent application number 93104811 discloses a high-strength weather-resistant modified polyvinyl chloride (PVC) material; its disadvantage is that rubber Among the plastic alloys, PVC has not been expanded, and the effect of plasticizing is poor, so it cannot be used as extrusion rubber.
[0004] In 2008, "Gansu Science and Technology" Volume 24, Issue 15, about the production of NBR / PVC co-precipitation rubber by emulsion blending method, disclosed the preparation method (NBR blended rubber). Mixing increases energy consumption and makes the extruded product rough and dull

preparation example Construction

[0021] A preparation method of carboxylated nitrile / polyvinyl chloride alloy rubber and plastic particles, comprising the following steps:

[0022] (a) Co-emulsification of polyvinyl chloride paste resin or suspension vinyl resin and dioctyl phthalate;

[0023] (b) adding carboxylated nitrile latex to the emulsified liquid obtained in step (a) for blending;

[0024] (c) Add anti-aging agent and heat stabilizer to the blended liquid obtained in step (b) and mix evenly, heat up to 55-70 degrees, add coagulant, and dehydrate to obtain carboxylated nitrile / polyvinyl chloride co-precipitated rubber powder product;

[0025] (d) Add vulcanizing agent to the co-precipitated rubber product obtained in step (c), pre-vulcanize on a twin-screw extruder at 80-120 degrees, and extrude to granulate.

[0026] In the step (b), the coagulant is any one of the mixtures of industrial salt, alum, magnesium sulfate and sulfuric acid in any ratio.

[0027] The preparation method of the carboxylat...

Abstract

The invention discloses carboxyl butyronitrile / polyvinyl chloride alloy rubber and plastic particles and a preparation method thereof. The carboxyl butyronitrile / polyvinyl chloride alloy rubber and plastic particles are prepared from the following components in parts by mass: 50-80 parts of carboxyl butyronitrile rubber, 10-40 parts of polyvinyl chloride and 5-40 parts of polyvinyl chloride. According to the invention, the particles can be made directly, thereby avoiding the physical process of mixing and vulcanization, and saving a lot of labor force and energy consumption; and the carboxyl butyronitrile / polyvinyl chloride alloy rubber and plastic particles have the advantages of smooth surface, good light sensation and good hand feeling.

Description

technical field [0001] The invention relates to carboxylated nitrile / polyvinyl chloride alloy rubber and plastic particles and a preparation method thereof. Background technique [0002] At present, the rubber-plastic alloy rubber produced in our country is used for molding products, and the kneader or screw extrusion is generally used for plasticization during plasticization. The mixed rubber cannot be used to extrude the rubber compound, because the rubber compound Rough appearance after exiting. [0003] The patent application No. 98115829O discloses a multi-component thermoplastic elastomer combination with improved filling, solubilization and vulcanization, which belongs to thermoplastic rubber-plastic alloy (TPV or TPV-S) filled and solubilized by blended modified materials. Solve the use of general-purpose, cheap materials and their modified combinations to produce low-cost new varieties of products; the patent application number 93104811 discloses a high-strength we...
