Do you know what material the high temperature resistant conveyor belt contains?

Each part of a single high temperature resistant conveyor belt uses four types of rubber materials: encapsulated rubber, buffer rubber, fabric friction adhesive and fabric adhesive.
Category 1: packing glue
The high temperature conveyor belt is affected by the impact of materials, wear and microbial erosion, as well as various aging effects. Therefore, the coating adhesive has good tensile strength. ≥ 18mpa), wear resistance (0.8 cm3/1.61 km), aging resistance and biological corrosion resistance. In addition, good viscosity and other technological properties are required. The key points of the formula design are as follows: raw rubber is based on natural rubber or mixed with a suitable amount of styrene-butadiene rubber, the rubber content is controlled by 50% ~ 55%. The vulcanization system adopts the traditional sulfur and accelerator combination system. The sulfur content in the natural rubber formula is about 2.5 parts by mass; the sulfur content in the SBR formula is 1.5-2.0 parts by mass. Sponsors were taken alone
DM, C accelerator
Z, Nobs and other aftereffect accelerators are suitable for SBR-containing rubber compounds. The reinforcing agent can choose high wear resistance carbon black, super wear resistance carbon black, etc. The dose is 40 ~ 50 pieces of high quality. Softeners are usually selected from a variety of oils, heavy oils, pine tar, coumarin resins and petroleum resins.
Second category: Buffer gum
Conveyor belt buffer adhesive is located between the packaging adhesive and the core layer, can increase the adhesive force between them, and can receive and release the impact force of the transport material, play a buffer role. The adhesive has good adhesion (adhesion between adhesive and fabric) ≥ 3.15n / MM), high elasticity, low temperature, good heat dissipation, good processability.
The crude rubber is made of natural rubber and butadiene rubber, with a rubber content of 50% to 55%. The high angle of inclination conveyor belt consists of three parts: Base band, bewilderment and partition. The edges prevent the material from sliding and falling. In order to avoid the drum conveniently, the shock absorber is designed in wave form. The function of the diaphragm is to support the material, in order to realize the transport of wide angle of inclination, adopt the type T-TC. The flange and diaphragm are connected to the Base Band by secondary vulcanization and have high connection resistance. The vulcanization system should use low sulfur content to improve the adhesion between the bonding line and the fabric layer.
Clase M.D
M and tmtd systems. The high angle of inclination conveyor belt consists of three parts: Base band, bewilderment and partition. The edges prevent the material from sliding and falling. In order to avoid the drum conveniently, the shock absorber is designed in wave form. The function of the diaphragm is to support the material, in order to realize the transport of wide angle of inclination, adopt the type T-TC. The flange and diaphragm are connected to the Base Band by secondary vulcanization and have high connection resistance. Carbon black is generally used in combination with high wear resistance semi-reinforced carbon black, the quantity should not be excessive, generally about 10 pieces of high quality. Softeners should be selected to add varieties with better viscosity, such as pine oil, solid gumalone, etc.
Category 3: Eraser
The important function of the high-temperature conveyor belt is to bond the canvas layer and the core material into a whole. The core material must have good bonding properties (the bonding strength between the fabric and the fabric is not less than 4.5 n / MM), fatigue strength (bending times of the fabric) ≥ 25,000 peeling/total peeling) and must have sufficient plasticity (plasticity). 0.5 ~ 0.6), has the function of flame retardant.
Category IV: natural rubber, 20 - 30 Parts of high-quality styrene-butadiene rubber, with a rubber content of about 50%. Separate sulfur sulfurization system, accelerator system. The promoters use m and DM alone or a small amount of tmtd to accelerate vulcanization, but care must be taken to avoid burning of rubber materials. Carbon black should be semi-reinforced carbon black or other soft carbon black with an amount of about 10 pieces of high quality. When mixed with Styrene-butadiene rubber, the amount of gumalone resin and petroleum resin should be properly increased, otherwise the adhesive strength of the fabric layer will decrease.
