The invention discloses an adhesive self-resistance heating / super-hydrophobic integrated gradient thin film material. The thin film material is made of adhesive resin, insulating resin, thermally andelectrically conductive filler and thermally conductive and insulating filler, wherein the adhesive resin and the insulating resin separately form a bonding layer and a substrate which are bonded together; and the thermally and electrically conductive filler and the thermally conductive and insulating filler are added to a middle layer and an upper layer of the substrate correspondingly to dividethe substrate into three gradient regions from top to bottom, wherein the surface of the uppermost region is constructed with a super-hydrophobic structure. The adhesive self-resistance heating / super-hydrophobic integrated gradient thin film material has the beneficial effects that (1) only the insulating resin is used in a main part, the functionalization of different regions is realized while ensuring that the interface influence between layers of different materials does not exist in a structure, mechanical properties are significantly improved, and stratification is not prone to occurring;and (2) anti-icing and de-icing are integrated into one, the icing time can be effectively delayed, low-energy electric heating de-icing can be achieved, and the energy utilization efficiency of aircrafts can be ultimately improved.

The invention provides a wear-resistant carbon fiber coating and a coating method thereof. Resin in a carbon fiber coating material is mixed and melted with a solvent, clay, a binder and a filler; under the action of a ball mill, a coating material which has uniform particle size and is less than 1000 meshes is obtained; with the combination of dispersion effect of a dispersion machine, the coating material can be better combined with the surface of carbon fiber. The coating material is coated in three layers during coating: the first layer and the second layer are coated under the ultravioletirradiation such that silicon dioxide ultrafine particles of the polymerization reactive functional group are dispersed therein to form a more stable coating; and the third layer of the coating material is uniformly scraped and synchronously solidified on a frame-type film applicator to strengthen the adhesion between the coating materials, and then the coating is less prone to delamination and the speed of corrosive particles entering the coating is effectively delayed. Thereby, the coating shows good chemical corrosion resistance and remarkable wear resistance.

The invention relates to a polyester resin adhesive. A polyester resin is formed by a polycondensation of polycarboxylic acid and a polyalcohol as a copolyester, wherein the polycarboxylic acid comprises 50 to 90 mol percent of aromatic dicarboxylic acid; the polyalcohol at least comprises 25 to 90 percent of C3 to C20 alkylene glycol; the specific gravity of the polyester resin is 1.15 to 1.30 g / cm<3>; and the intrinsic viscosity of the polyester resin is 0.2 to 1.2. 100 weight parts of the polyester resin and 5 to 30 weight part of a crosslinker undergo a cross-linking reaction to form an adhesive material of which the gel content is over 30 percent. The adhesive is used for making a back protection film of a solar cell module and makes the solar cell products stand outdoor long-term use tests.
