Problems solved by technology

However, according to the results of multiple risk assessments, some phthalates may harm reproductive function, cause sensitization, cause asthma, and even cancer
[0003] Among the rubber compound formulations used in the production of wire and cable, many of them failed to pass the test because they contained excessive phthalates, which brought great troubles to manufacturers and great safety hazards to consumers and users.

Embodiment 1

[0019] Weigh 25kg of 135B chlorinated polyethylene, 25kg of talcum powder, 25kg of calcium carbonate, 3kg of plasticizer TOTM, 1kg of vulcanization aid TAIC, 1kg of vulcanizing agent lauryl peroxide, 3kg of active agent MgO, 0.5 kg of slippery paraffin kg, stabilizer 1kg, flame retardant powder Sb 2 o 3 3kg, carbon black 2kg, other compounding agents 3kg. The above raw materials are blended and kneaded for a period of time, then extruded and vulcanized to obtain a phthalate-free electric wire.

[0020] The components and weights of Examples 2 to 5 are shown in the table below, and the production process is similar to that of Example 1, so details are not repeated here. The electric wire products obtained in Examples 2 to 5 do not contain phthalates, except that they meet the requirements of national electric wire product safety regulations.

Abstract

The invention relates to the technical field of special rubber materials, in particular to an environment-friendly rubber material that does not contain phthalate. The rubber material contains raw materials with the following parts by weight: 20 parts to 30 parts of chlorinated polyethylene, 15 parts to 30 parts of talcum powder, 15 parts to 30 parts of calcium carbonate, 2.0 parts to 5.0 parts of plasticizers, 0 parts to 2.0pbw of vulcanization aids, 0 parts to 2.0 parts of vulcanizers, 0 part to 5.0 parts of activating agents, 0 part to 1.0 part of lubricant prescription, 0 part to 2.0 parts of stabilizers, 2.0 parts to 5.0 parts of fire retardants, 1.0 part to 10 parts of carbon black and 0 part to 5.0 parts of other compounding agents. The rubber material is mainly applicable to manufacturing the insulation material of electrical wires, which is prepared by adopting the formula to well mix the raw materials and carrying out the steps of mixing, extrusion molding and vulcanization by adopting the current technique. The products prepared by the formula, such as electric wires, does not contain phthalate apart from meeting the PAHs inspection standards and ensure that the potential safety hazard of consumers and users can be eliminated.

Description

Technical field: [0001] The invention relates to the technical field of special rubber materials, in particular to an environmentally friendly rubber material without phthalates. Background technique: [0002] Due to the widespread presence of a large number of phthalates (Phthalates) in PVC products at present, phthalates have been used for 40 years, and they are widely used in rubber, plastic, chemical and other fields, including the production of toys , is also used in medical products such as urinary catheters, intravenous catheters and sanitary gloves. However, according to the results of multiple risk assessments, some phthalates may harm reproductive function, cause sensitization, cause asthma, and even cancer. [0003] Among the rubber compound formulations used in the production of wire and cable, many of them failed to pass the test because they contained excessive phthalates, which brought great troubles to manufacturers and great safety hazards to consumers and ...
