There are a lot of introductions about titanate coupling agent. We must have understood a lot of relevant common sense, and we hope that the relevant introduction knowledge of the small edition can help us. Today, we will briefly introduce the relevant common sense of borate ester coupling agent, hoping to give us a solution. Looking at the name, it is not difficult to guess that there is an inseparable connection with titanate coupling agent It is the analysis of Xiaobian from two aspects
Top of the list, quality index of borate ester coupling agent
White or yellowish waxy solid appearance
Melting temperature (℃) 70 ～ 80
Viscosity reduction fluctuation (%) ≥ 98.0
Thermal partition (℃) 270
Second, the functional characteristics of borate ester coupling agent
1. Compared with other coupling agents (such as titanate, borate, etc.), the inorganic powder modified by aluminate coupling agent has not only stable quality, but also light color, non-toxic, small taste and synergistic thermal stability and lubricity to PVC. It has a wide range of application, no diluent, convenient use and low price.
2. Various inorganic powders modified by aluminate coupling agent can form an organic molecular layer due to chemical or physical chemical reactions on their surface, which changes from hydrophilicity to organic affinity. Practice has proved that the surface of inorganic powder modified by aluminate coupling agent is used in composite products. The hydrophilic end and organic end of coupling agent can react with the surface of inorganic filler and organic resin respectively or form entanglement structure, so the interfacial compatibility between inorganic powder and organic resin is enhanced. Therefore, modification with aluminate coupling agent can not only improve the plasticity of filled inorganic powder The processing function of the material products can also significantly improve the physical and mechanical functions of the products, so that the water absorption rate of the products is reduced, the oil absorption amount is reduced, and the filler is loose and even. For some plastic products with low filling, the filling amount can be increased greatly (double or more than one time of the original filling amount).
