Problems solved by technology

[0003] Shock absorption, weight reduction and excellent elasticity are important indicators of rubber soles. If the sole is too heavy, it will easily cause fatigue if worn for a long time. If the elasticity and shock absorption performance is poor, it will easily shock the back of the head when bouncing on the ground or jumping from a high place. , especially unfavorable to soldiers and athletes

Embodiment 1

[0023] Embodiment 1, the preparation of styrofoam and performance test thereof

[0024] The styrofoam in the present embodiment is made of the NR of 70.0phr, the CR of 30.0phr, the reinforcing filler of 80.0phr, the zinc oxide of 5.0phr, the accelerator TMTD of 1.5phr, the accelerator DM of 1.0phr, the accelerator DM of 1.5phr Sulfur, 2.0phr foaming agent AC, 2.0phr foaming agent H; the reinforcing filler is composed of 40.0phr high wear-resistant carbon black, 10.0phr calcium carbonate and 30.0phr rubber powder.

[0025] The specific preparation method is as follows: Use an open mill to mix rubber, first pass cooling water to ensure that the temperature of the roller is below 80°C, first masticate CR, then add NR to masticate together, and then add reinforcing filler, Zinc oxide, accelerator TMTD and accelerator DM, finally add foaming agent and sulfur, after the material powder is fully mixed into rubber, repeat rubber tapping and mixing, the whole process is 15min, and fina...

Embodiment 2

[0028] Embodiment 2, the preparation of styrofoam and performance test thereof

[0029] The component that is used to prepare styrofoam in the present embodiment is substantially the same as that in embodiment 1, and difference is: the consumption of blowing agent is adjusted to the foaming agent AC of 2.0phr; Other mixing process and embodiment Same as in 1.

[0030] Utilize the method identical with embodiment 1 to carry out performance test and the observation of microstructure to the styrofoam prepared in this embodiment, its performance is as shown in table 1, and its scanning electron micrograph is as follows figure 2 as shown in b.

[0031] It can be seen from the data in Table 1 that with the increase of the amount of foaming agent, the foaming density of the foamed rubber decreases, which is more conducive to the weight reduction and shock absorption of finished shoes. But at the same time, the increase in the amount of foaming agent leads to a decline in the mecha...

Embodiment 3

[0035] Embodiment 3, foaming / compact glue injection into shoes

[0036] First, use the internal mixer to mix the solid rubber layer according to the following formula (phr), and then produce the tablet:

[0037] CR 65.0; NR 35.0; zinc oxide 5.0; magnesium oxide 8.0; flame retardant 15.0; black ointment 10.0; antiaging agent 40102.5; accelerator M 1.0; rubber accelerator DM 1.0; sulfur 1.5; Carbon black 45.0; petroleum jelly 8.0; motor oil 3.0.

[0038] Mix the styrofoam using an open mill. First pass cooling water to ensure that the temperature of the roller is below 80°C, first masticate 20.0phr of CR, then add 80.0phr of NR to masticate together, then add 40.0phr of high wear-resistant carbon black, 10.0phr of Calcium carbonate, 30.0phr rubber powder, 8.0phr zinc oxide, 1.0phr accelerator TMTD, 1.0phr rubber accelerator DM, finally add 1.5phr foaming agent AC, 1.0phr foaming agent H and 2.0phr After the raw material powder is fully mixed into the rubber, the rubber is rep...

Abstract

The invention discloses a compact/foamed rubber sole and its special foaming rubber. The foaming rubber is prepared by using the following parts, by mass, 60.0-80.0 parts of natural rubber, 20.0-40.0 parts of chloroprene rubber, 50.0-100.0 parts of a reinforcing filler, 5.0-10 parts of zinc oxide, 1.0-2.5 parts of a vulcanization accelerant, 0.5-2.0 parts of sulfur, and 0.5-5.0 parts of a foaming agent. The invention further provides the compact/foamed rubber sole. The compact/foamed rubber sole is composed of a solid layer and a foaming layer; and the foaming layer is made by using the foaming rubber. The foaming rubber has the advantages of good thermal stability, uniform foam hole, good dimension stability, low density, softness, good elasticity, flame retardation and the like. The foaming rubber can be used in the sole to effectively reduce the weight, improve the elasticity and increase the comfortableness of the sole.

Description

technical field [0001] The invention relates to a dense / foaming rubber sole and special foaming rubber thereof. Background technique [0002] Foam rubber, also known as sponge rubber, has a porous structure and is a composite material composed of rubber and pores. Therefore, it has the characteristics of low density, good elasticity, saving raw materials, heat insulation, sound insulation, good elasticity, and can absorb impact loads. It is widely used in aerospace, automobiles, packaging, construction, shoemaking, sporting goods and other related fields. Due to its unique characteristics, foam rubber is used in shoe sole materials to achieve good results. [0003] Shock absorption, weight reduction, and good elasticity are important indicators of rubber soles. If the sole is too heavy, it will easily cause fatigue if worn for a long time. If the elasticity and shock absorption performance is poor, it will easily shock the back of the head when bouncing on the ground or jum...
