preparation example Construction

[0038] A preparation method for a one-time molding lightweight cushioning composite outsole, comprising the following steps:

[0039] In the first step, the raw materials of anti-slip rubber blocks, the raw materials of wear-resistant rubber blocks, and the raw materials of lightweight rubber blocks are respectively refined to obtain the refined anti-skid rubber block, the wear-resistant rubber block, and light rubber block of glue;

[0040] In the second step, put the rubber material of the refined anti-skid rubber block, the rubber material of the wear-resistant rubber block, and the rubber material of the lightweight rubber block on the corresponding positions of the bottom of the outsole, and vulcanize for 60-120 seconds. The vulcanization temperature is 150±5 degrees, the pressure is 10-12MPa, and then put the rubber material of the foamed rubber layer on the top of the bottom rubber material, and vulcanize for 480 seconds to 540 seconds, the curing temperature is 150±5 d...

Embodiment 1

[0044] Such as figure 1 and figure 2 As shown, a one-time molded lightweight cushioning composite outsole includes a bottom layer 1 and a foam rubber layer 2 in the inner cavity of the bottom layer; the forefoot portion 11 of the bottom layer 1 is a non-slip rubber block 101, and the heel portion 12 of the bottom layer The wear-resistant rubber block 102 is connected by a lightweight rubber block 103 between the forefoot portion 11 and the heel portion 12 . The non-slip rubber block and the light rubber block are connected by vulcanization and cross-linking, and the wear-resistant rubber block and the light rubber block are connected by vulcanization and cross-linking; The foam rubber layers are connected by vulcanized crosslinks.

[0045] Anti-slip patterns 13 are provided on the bottom surfaces of the forefoot portion 11 and the heel portion 12 of the bottom layer.

[0046] The anti-slip pattern 13 includes unit patterns 130 arranged in an array on the bottom surface of ...

Embodiment 2

[0065] A one-time molded lightweight cushioning composite outsole, the difference from Example 1 is that the raised height of the triangular pattern and the circular pattern is 2mm, and the recessed depth of the groove I, groove II, and groove III is 2mm. The horizontal stripe groove 6 has a width of 1.3 mm and a depth of 2 mm.

[0066] The raw material of the non-slip rubber block is composed of two parts, the first part is composed of the following raw materials in parts by weight: 30 parts of natural rubber (NR), 12 parts of butadiene rubber (BR), 13 parts of solution polystyrene butadiene rubber (SSBR), 3 parts of active zinc oxide, 1 part of octadecanoic acid, 0.3 parts of N-isopropyl-N'-phenyl-p-phenylenediamine; 0.2 parts of 2,2,4-trimethyl-1,2-dihydroquinoline 30 parts of white carbon black, 2.5 parts of anti-slip agent NOVARES C10, 1 part of si-69 silane coupling agent, 1 part of polyethylene glycol.

[0067] The second part is the amount added on the basis of the f...

Abstract

The invention provides a one-step molded light-weight cushioning composite outsole and a preparation method thereof. The one-step molded light-weight cushioning composite outsole comprises a bottom layer and a foamed rubber layer in an inner cavity of the bottom layer, and the bottom layer comprises at least one antiskid rubber block, at least one wear-resistant rubber block and at least one connecting rubber block; when the outsole and the foaming rubber layer in the inner cavity of the bottom layer are vulcanized, the wear-resisting rubber block and the connecting rubber block of the bottomlayer of the outsole are vulcanized, and the anti-skidding rubber block and the connecting rubber block of the bottom layer of the outsole are vulcanized, the flowing crosslinking of rubber materialsis finished, so the use of chemical materials such as treating agents and adhesives is not needed; the environment pollution caused by chemical materials is avoided, the production cost of the shoes and boots is reduced, and the bonding effect of the shoes and boots and the appearance effect of the shoes and boots are ensured. In addition, the outsole bottom layer is composed of the anti-skid rubber blocks and the wear-resisting rubber, the anti-skid effect and the wear-resisting effect can be achieved, and the foaming rubber layer has the effects of light weight and shock absorption.

Description

technical field [0001] The invention relates to a composite outsole, in particular to a preparation method of a one-time molded lightweight shock-absorbing composite outsole. Background technique [0002] Generally, the composite outsole adopts the mode of vulcanizing the wear-resistant outsole and the EVA outsole first, and then bonding the wear-resistant outsole and the EVA outsole together by brushing treatment agents, adhesives and other chemical materials. Due to the influence of the adhesive system and artificial factors, the adhesive effect fluctuates from time to time during the production process, and due to the use of chemical materials such as treatment agents and adhesives, there is a certain amount of environmental pollution during the production process. Contents of the invention [0003] In order to solve the above problems, the present invention provides a light-weight shock-absorbing composite outsole and its preparation method. The setting of the foam ru...
