Problems solved by technology

Diethylene glycol or triethanolamine is often used to activate the main rubber in the raw material composition of the enclosure. However, the vulcanized rubber obtained in this way has low whiteness, low gloss, and is matte. Poor shape retention, exposed shoe sole marks, easy to cause pressure deformation, and unclear product appearance; and the yellowing resistance level under the sun lamp method is lower than level 3; the size of the enclosure is unstable, it is difficult to ensure the stability of the appearance, the product grade Low; the physical properties of this vulcanized rubber are: tensile strength 7-9Mpa, elongation at break 300-400%, poor flexural resistance
The above performances all cause the existing enclosures to have many deficiencies, which are difficult to meet the needs of use.

Embodiment 1

[0018] This embodiment provides a white enclosure, which includes the following raw materials: No. 1 standard glue 90kg, zinc oxide 3kg, stearic acid 1.1kg, diethylene glycol 2.5kg, anti-yellowing accelerator 2kg, anti-aging agent RDZ 1.1kg, Anti-heat oxygen agent RF1.7kg, brightener 2.6kg, sulfur 1.7kg, superfine calcium carbonate 78kg, imported titanium dioxide 35kg, ultramarine 0.35kg, permanent purple masterbatch 0.45kg and white carbon black 28kg. The manufacture method of this white apron comprises the following steps:

[0019] Mastication: Put 90kg of No. 1 standard rubber on the open mill, and use 0.1mm roller distance to carry out 3 times of thin pass plastication treatment. Among them, each time of thin pass plastication treatment, firstly carry out 12 times of thin pass plastication, and open enough Cooling water, and then parked for 28 hours to obtain No. 1 standard rubber with Vickers plasticity between 0.6-0.65, and then parked for 28 hours to obtain plastication...

Embodiment 2

[0023] This embodiment provides a white enclosure, which includes the following raw materials: No. 1 standard glue 100kg, zinc oxide 4kg, stearic acid 1.5kg, diethylene glycol 3kg, anti-yellowing accelerator 2.5kg, anti-aging agent RDZ 1.5kg, Anti-heat oxygen agent RF2kg, brightener 3kg, sulfur 2kg, superfine calcium carbonate 83kg, titanium dioxide 40kg, ultramarine 0.43kg, permanent purple masterbatch 0.53kg and white carbon black 33kg. The manufacture method of this white apron comprises the following steps:

[0024] Mastication: Put 100kg of No. 1 standard rubber on the open mill, and use 0.1mm roller distance to carry out 3 times of thin pass plastication treatment. Among them, each thin pass plastication treatment is firstly carried out 15 times of thin pass plastication, and opened enough Cooling water, and then parked for 24 hours to obtain the No. 1 standard rubber with a Vickers plasticity between 0.6-0.65, and then parked for 24 hours to obtain the plasticized stand...

Embodiment 3

[0028] This embodiment provides a white enclosure, which includes the following raw materials: No. 1 standard glue 105kg, zinc oxide 4kg, stearic acid 1.6kg, diethylene glycol 3.1kg, anti-yellowing accelerator 2.4kg, anti-aging agent RDZ 1.5kg , Anti-heat oxygen agent RF2.0kg, brightener 2.9kg, sulfur 1.8kg, superfine calcium carbonate 80kg, titanium dioxide 39kg, ultramarine 0.40kg, permanent purple masterbatch 0.50kg and white carbon black 32kg. The manufacturing method of the white skirt provided in this example is basically the same as that provided in Example 2, except that the quality of each component in the raw materials of the white skirt is different.

Abstract

The invention provides a white edge strip comprising the following raw materials in parts by weight: 90-110 parts of 1# glue, 3-5 parts of zinc oxide, 1.1-1.9 parts of stearic acid, 2.5-3.5 parts of diethylene glycol, 2-3 parts of a yellowing-resistant accelerant, 1.1-1.8 parts of an anti-aging agent RDZ, 1.7-2.3 parts of a thermal antioxidant, 2.6-3.4 parts of a brightener, 1.7-2.3 parts of sulphur, 78-88 parts of superfine calcium carbonate, 35-45 parts of titanium dioxide, 0.35-0.48 part of ultramarine blue, 0.45-0.58 part of permanent violet masterbatch and 28-38 parts of white carbon black. The white edge strip has the advantage of good yellowing resistance. The invention also provides a production method of the white edge strip.

Description

technical field [0001] The invention relates to a fence and a manufacturing method thereof, in particular to a white fence and a manufacturing method thereof. Background technique [0002] At present, when the shoe manufacturing industry uses leather or rubber materials, a circle of apron is usually glued on the upper of the shoe to play the role of fastening, impact resistance, and falling off. Diethylene glycol or triethanolamine is often used to activate the main rubber in the raw material composition of the enclosure. However, the vulcanized rubber obtained in this way has low whiteness, low gloss, matte type, unstable stiffness of the semi-finished rubber material, and out-of-shape patterns. Poor shape retention, exposed shoe sole traces, easy to cause pressure deformation, and unclear product appearance; and the yellowing resistance level under the sun lamp method is lower than level 3; the size of the fence is unstable, it is difficult to ensure the stability of the a...
