preparation example

[0066] The preparation method of modified adsorbent:

[0067] S1: Add starch into the alcohol solution with a volume fraction of 50%, and stir until the starch and the alcohol solution with a volume fraction of 50% are uniformly mixed to obtain a mixture A;

[0068] S2: Put mixture A in a constant temperature water bath at 50°C for 15 minutes, then add dispersant to mixture A and stir until the dispersant and mixture A are uniformly mixed to obtain mixture B;

[0069] S3: under the condition that the temperature of the water bath is 50°C, add the mineral filler to the mixture B, and stir until the mineral filler and the mixture B are uniformly mixed to obtain the mixture C;

[0070] S4: After the mixture C is cooled to room temperature and condensed into a mass, the mixture C is pulverized to obtain the modified adsorbent.

[0071] According to the preparation method of the above-mentioned modified adsorbent, the modified adsorbent 1, the modified adsorbent 2 and the modified...

Embodiment

[0075] The preparation method of environment-friendly elastomer material:

[0076] S11, drying the modified adsorbent at a temperature of 50°C;

[0077] S12, adding ethylene-vinyl acetate copolymer, toughening agent, heat stabilizer, antioxidant, modified adsorbent, etc. into a high-speed mixer in turn, stirring and mixing at room temperature to obtain a mixture D;

[0078] S13. Put the mixture D in an ordinary twin-screw extruder, extrude it at 155°C, draw it, and then cool it in a water tank to obtain an environmentally friendly elastomer material.

[0079] The ratio of raw materials in each embodiment is shown in the following table 3, wherein, toughening agent A represents styrene-isoprene-styrene block copolymer, and toughening agent B represents styrene-ethylene-butylene-styrene Block copolymer, toughener C means styrene-ethylene-butylene-styrene block copolymer

Abstract

The invention discloses an environment-friendly elastomer material for coating polyester yarns and a preparation method thereof, belongs to the technical field of elastomer materials, and aims to solve the problem that the elastomer material easily generates odor in a high-temperature state. The environment-friendly elastomer material for coating the polyester yarns is prepared from the followingraw materials in parts by weight: 50-70 parts of ethylene-vinyl acetate copolymer; 10 to 20 parts of a toughening agent; 5-10 parts of a heat stabilizer; 5-10 parts of an antioxidant and 4-8 parts ofa modified adsorbent, wherein the modified adsorbent is prepared from the following raw materials in parts by weight: 30-40 parts of a mineral filler; 10 to 15 parts of starch and 1-2 parts of a dispersant; the environment-friendly elastomer material has good thermal stability, and meanwhile, the modified adsorbent with good adsorption stability is added, so that the problem that the environment-friendly elastomer material easily emits odor in a high-temperature state is favorably improved. The preparation method disclosed by the invention has the advantages of simple process and convenience in operation.

Description

technical field [0001] The invention relates to the technical field of elastomer materials, in particular to an environmentally friendly elastomer material for covering polyester filaments and a preparation method thereof. Background technique [0002] Elastic bands, also known as elastic bands, are widely used in the preparation of sofas, and can act as a skeleton in the sofa frame to carry the sofa cushions. Among them, the elastic belt mainly includes an inner core made of industrial high-strength polyester yarn or polypropylene yarn and an outer peripheral elastic sheath covering the inner core. The elastic sheath can protect the polyester yarn or polypropylene yarn. [0003] At present, most of the sheaths covering the outside of the inner core are mainly made of polyvinyl chloride resin and various heat stabilizers, stabilizers, flame retardants, etc. Wherein, when the polyvinyl chloride resin used to prepare the elastic band contains residual vinyl chloride monomer, ...
