[0003] Existing rain boots are heavy in weight and inconvenient to wear; foamed rubber has lighter performance than non-foamed rubber. Although the existing rubber is light in weight after being foamed, its mechanical properties are not ideal. Can be used for rain boot materials with low performance requirements and limited service life

Embodiment 1
[0011] A lightweight rain boot material, the components of which are calculated in parts by weight:
[0012]
[0013]
[0014] Preparation Process:
[0015] Put the plastic material that has reached the standard for plastication (plasticity is 0.4, and keep it parked for 12 hours) into the internal mixer, add various fillers (except sulfur; aluminum alloy barrier explosion-proof materials need to be added after manual crushing), and mix at 90°C for 7 to 8 hours. Minutes, start mixing at 85°C after mixing and add sulfur. After the sulfur and rubber are mixed completely, make triangular bags for 5 to 8 times. After being rolled, it enters into a five-roll machine for calendering, and the roll temperatures are 75°C, 80°C, 85°C, 90°C, and 95°C from bottom to top.

The invention belongs to the field of preparation of rain boot materials, and especially relates to a lightweight rain boot and a making method thereof. The material of the lightweight rain boot is prepared on the basis of natural rubber modification, and comprises 70-75 parts of natural rubber, 25-30 parts of styrene butadiene rubber, 4-6 parts of high styrene, 2-2.5 parts of sulfur, 0.2-0.25 parts of a promoter M, 0.2-0.3 parts of a promoter D, 4-5 parts of zinc carbonate, 0.5-1 part of stearic acid, 0.3-0.6 parts of an antioxidant 2246, 20-30 parts of an aluminum alloy barrier explosion-proof material, 2-3 parts of polyethylene glycol, 10-20 parts of fiber powder, 2-3 parts of carbon black and 2-4 parts of C5 resin. The lightweight rain boot simultaneously has the lightweight characteristic of the material and mechanical use performances.
Description
technical field [0001] The invention belongs to the field of rain boot material preparation, in particular to a lightweight rain boot and a preparation method. Background technique [0002] Rain boots are a kind of rubber or plastic overshoes that reach to the ankle when it rains and is muddy. It is an excellent equipment for traveling in rainy days. Up to the knee, the material is mainly rubber. [0003] Existing rain boots are heavy in weight and inconvenient to wear; foamed rubber has lighter performance than non-foamed rubber. Although the existing rubber is light in weight after being foamed, its mechanical properties are not ideal. It can be used for rain boot materials with lower performance requirements and limited service life. Therefore, there is a need to provide a rain boot material with light weight characteristics and strong mechanical properties. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a...
