The current trend is that friction materials such as automobiles and trains at home and abroad are becoming loose, porous, lightweight, and the amount of organic substances is reduced as much as possible, but the self-binding properties of inorganic substances must be increased. In the direction of energy saving, low carbon, environmental protection and safety, our company's scientific researchers have successfully carried out high-alumina vanadium after a large number of scientific research tests on NFJ inorganic high-temperature secondary adhesives used in friction materials and sealing materials. Modification, increased high temperature resistance, light specific gravity, microporosity, plasticity, abrasion resistance, impact resistance, non-swelling at high temperature, non-shrinking at low temperature, to achieve the inorganic substances gradually increase in viscosity as the temperature increases. The secondary bonding effect reduces the performance slippage during high temperature braking and improves the functional stability during high temperature braking.

First, the production principle:

NFJ inorganic high-temperature secondary binder is made of high-alumina vanadium with a specific structure through a special foaming treatment to make it a rough, loose, porous, plastic and low-density porous reinforcing material. According to the needs of different families, Manufactured into a variety of granularity and specific gravity products.

Second, it has a good mutual replacement performance with the binder, which can greatly reduce the amount of binder

1. NFJ inorganic high temperature secondary adhesive has good plasticity

   Deformation occurs during the pressing process. During the use of friction materials, as the temperature increases, the viscosity gradually increases, increasing the toughness of the brake pads during braking, and reducing the slippage at high temperatures. This enhances NFJ inorganic high temperature The secondary adhesive and the adhesive have a mutual replacement effect (because the adhesive gradually decreases in viscosity as the temperature increases), it has the effect of an inorganic high-temperature secondary adhesive, which can greatly reduce the organic adhesive. For the amount of 2 to 3 parts of NFJ non-polar high temperature secondary binder, the amount of 1 to 2 parts of binder can be reduced.

2. Make the synthetic friction material easy to uniform when mixing

   The modified NFJ inorganic high-temperature secondary binder has good dispersibility in friction materials. The principle is that the modified NFJ inorganic high-temperature secondary binder has a finer particle size, a rough surface, a lighter specific gravity, and micropores. Dispersion and uniform particle size distribution. NFJ inorganic high-temperature secondary adhesive can gradually reduce the viscosity when the friction material is braked, which can reduce the slippage phenomenon during high-temperature braking.

3.Improve the toughness and impact resistance of friction materials

   NFJ inorganic high-temperature secondary binder cooperates with various fibers, deforms under pressure, has good affinity with other fibers, enhances the surface toughness of other fibers, and improves the impact resistance of friction materials.

4.Improve the sealing performance of sealing materials

   NFJ inorganic high-temperature secondary adhesive has good sealing performance in sealing materials and can greatly reduce the amount of adhesive. It does not swell at high temperature and does not shrink at low temperature, which can achieve a good sealing effect.

5, easy to demold the surface feel good

   NFJ inorganic high-temperature secondary binder has light specific gravity, good dispersion, and good surface density after easy release. However, the material is lighter and reduces the total weight of the friction material.

6.Improve the wear resistance of friction materials

   NFJ inorganic high temperature secondary adhesive has improved the wear resistance of friction materials in Mocha materials. The hardness of the modified NFJ inorganic high temperature secondary adhesive reaches 5-Mohs hardness. Good dispersion performance and high temperature resistance. Therefore, it can achieve the desired performance.
