Phthalate ester coupling agent

The phthalate ester coupling agent can provide good coupling effect for the filler and the polymer system. The phthalate ester coupling agent can generate chemical combination between the inorganic powder and the organic matrix interface, and has the unique performance of forming a monomolecular film on the surface of the inorganic powder and not forming a polymolecular film on the organic interface. Under the condition of the existence of excessive coupling agent, the surface energy of the molecules can be changed, the viscosity is greatly reduced, and the dispersion performance among materials is enhanced.

Preferably, the phthalate coupling agent is selected from the group consisting of isopropyl tris (dioctylphosphato) phthalate, isopropyl tris (isostearyl) phthalate, isopropyl tris (dodecylbenzenesulfonyl) phthalate, isopropyl tris (dioctyl) phosphate phthalate, isopropyl tris (n.n-dimethyl-ethylamine) phthalate, isopropyl tris (dioctyl) pyrophosphate phthalate, tetraoctyloxybis (dilauryl phosphite) phthalate, dioctyl titanium oxydoacetate, isopropyl tris [ di (oleoyl) ] phthalate, isopropyl tris (phosphate) phthalate, isopropyl tris (pyrophosphate) phthalate, bis (pyrophosphate) titanium oxydoacetate, tetraisopropyl (phosphite) phthalate, isopropyl tris (oleoyloxy) phthalate, isopropyl tris (alkoxy) phthalate, isopropyl tris (iso-higher fatty acid) phthalate, At least one of isopropyl tri (isostearic acid) phthalate ester and bis (methacrylic acid) ethylene phthalate ester.

More preferably, the phthalate coupling agent is selected from isopropyl tris (dioctylphosphonoxy) phthalate, available under the trademark KR-01204 from Viruna chemical Co., Ltd, Guangzhou.

Surface active agent

The surfactant is a substance which is added in a small amount and can cause the interface state of a solution system to change obviously. Has fixed hydrophilic and lipophilic groups and can be directionally arranged on the surface of the solution. The molecular structure of the surfactant has amphipathy: one end is a hydrophilic group, and the other end is a hydrophobic group; the hydrophilic group is often a polar group, such as carboxylic acid, sulfonic acid, sulfuric acid, amino or amino groups and salts thereof, hydroxyl, amide, ether linkages, and the like may also be used as the polar hydrophilic group; whereas the hydrophobic group is often a non-polar hydrocarbon chain. In the present application, it was found that when the surfactant anionic surfactant and nonionic surfactant are used in a weight ratio of 2.3:1, the pearl powder not only enhances the dispersing ability of the pearl powder, but also enhances the tensile property of the fiber. This is probably because the weight ratio of anionic surfactant to nonionic surfactant was 1: 1, the dispersing performance of the pearl powder can be enhanced doubly, but when the content of the anionic surfactant is higher than that of the nonionic surfactant (the weight ratio of the anionic surfactant to the nonionic surfactant is 2.3:1), the dispersing performance of the pearl powder is changed, and the excessive sulfonic acid group of the anionic surfactant can form strong hydrogen bond action with the hydroxyl group of the viscose fiber, so that the binding force between molecules is improved, and the toughness of the formed fiber is enhanced; and when the weight ratio of the anionic surfactant to the nonionic surfactant exceeds 2.3:1, the sulfonic groups in the anionic surfactant in the system are further increased, so that the water absorption swelling performance of the fiber material is overlarge, more water can be absorbed among three-dimensional networks in the material, the stretching degree among molecular chains is increased, the tensile capacity of the molecular chains for resisting external stress is reduced when the material is stretched by external force, and the stretching performance of the pearl protein fiber is weakened.
