Description
Technical field
The present invention relates to the organic high molecular compound field, relate to the macromolecular compound that only obtains, be specifically related to silicone resin with the silica reaction.
Background technology
Have in the silicone resin-the Si-O-Si-structure, demonstrate performances such as good weathering resistance, thermotolerance, anti-stain characteristic and chemically stable.But pure silicone resin needs hot setting, and long construction inconvenience set time, and with the poor adhesive force of metallic substance, poor solvent resistance, physical strength are not high, cost an arm and a leg, so its use receives restriction to a certain degree simultaneously.Other resins commonly used carry out modification to it.Other resins such as use epoxy resin carry out modification to silicone resin, can improve the metal sticking power of resin, hardness and mechanical property.For example use bisphenol A epoxide resin p-methylphenyl silicone resin such as Deng Ming mountain carries out modification, obtains fire resistant epoxy modified organic silicone resin (Deng Mingshan, golden double happiness; The Huanghai Sea, the development of epoxy modified silicone high-temperature resistant coating, Anhui chemical industry; 2000,103 (2), 27-29).But the epoxy modified silicone resin difference of hardness, mechanical property can not satisfy market demands.
Polyamide resin has good thermotolerance, wearability, chemical proofing and good mechanical performance and processing characteristics, and frictional coefficient is low, and certain flame retardant resistance is arranged, and is easy to processing, is widely used to be engineering plastics.The consistency of polymeric amide and various kinds of resin is good, in coating industry, is used widely.But the polyamide resin molecular weight is big, and is poorly soluble, and viscosity is high, and difficult and other resins carry out chemical modification.In order to obtain LV, the polyamide resin that solvability is good, use dimeracid commonly used and diamine polymerization.For example Wu builds good grade (Wu Jianliang, the development of low-molecular-weight polyamide resin, Zhejiang chemical industry, 2004,35 (03), 19) with Rice pollard oil raw material of fatty acid synthesis of dimmer acid, obtains lower molecular weight with the polyethylene polyamine polymerization again, low viscous polymeric amide.But the low-molecular-weight polyamide resin poor heat resistance of preparation, end group activation functional group content is few, can not improve the resistance toheat of other resins such as epoxy resin.
Hyperbranched polymer has highly branched structure and a large amount of end group reactive groups, has high resolution, LV and higher chemical reactivity etc.These make hyperbranched polymer demonstrate tempting application prospect in many aspects.LV makes hyperbranched polymer be fit to be applied to high solid component coating, can reduce system viscosity with the blend of line polymer coating, and the improvement system is mobile; High solvability can reduce the consumption of solvent, reduces cost, and reduces noxious gas emission; It is less that highly branched structure makes that the hyperbranched polymer molecule interchain tangles, and is difficult for crystallization, makes coating have good film forming properties.But the molecular weight of filming that forms after the hyperbranched polymer film forming is low, and cross-linking density causes the bad mechanical property of filming for a short time, and chemical-resistant can meet the demands; The film coated surface that forms after the hyperbranched polymer film forming simultaneously contains abundant reactive group, reduces the water resistance of filming.
