The invention discloses a normal-temperature phosphating fluid for drawing steel. The liquid is prepared by nitrate, nitrite, nitroguanidine, molybdate, phosphate, an accelerant and deionized water. The liquid can be used for performing normal-temperature phosphating on the steel for drawing, and can reach a same effect under a relatively-high-temperature phosphating; under the normal temperature, after 3 to 5 minutes, a layer of black, even and compact phosphating film can be formed on the surface of the steel, and the corrosion resistance is tested to be above the national standard. The problems of large high-temperature phosphating liquid consumption, high possibility in stripping, long phosphating time and the like are solved.

Provided are a polyhedral oligomeric silsesquioxane compound containing mercapto polyfunctional group shown as general formula (1), its composition used for preparing the soft template for imprinting and the imprinting process, wherein R1 is -CH2-CH2-CH2-SH, and m represents the integer of 3 to 12; R2 is unsubstituted or substituted alkyl group, unsubstituted or substituted alkoxy, unsubstituted or substituted ester group, and unsubstituted or substituted aryl group respectively, and the said substituent group is halogen; n represents the integer of 1 to 12. The composition is a high hydrophobic photoresist. When the composition is applied to prepare nanoimprinting template, a high precision structure can be achieved and the recycling rate of the template may be improved.

The invention discloses an insulation stretch resistant coating, a preparation method and an application thereof. The coating comprises the following components of 15-35 parts of a polyester resin A, 5-25 parts of a polyester resin B, 3.5-5 parts of an amino resin, 0-0.5 part of an adhesion promoter, 0.1-0.2 part of a slip additive, 2.5-4 parts of a surface modification agent, 0.1-0.2 part of an antifoaming agent, 0.1-0.2 part of a flatting agent and 50-55 parts of an organic solvent. The method firstly mixing the polyester resin A, the polyester resin B, the amino resin and the organic solvent, and then adding and evenly mixing the adhesion promoter, the surface modification agent, the slip additive, a catalyst, the antifoaming agent and the flatting agent to obtain the insulation stretch resistant coating. The insulation stretch resistant coating is free from yellowing after the coating is roasted for 3 minutes at the temperature of 270 DEG C and capable of resisting high voltage of 1050V; the appearance of a capacitor paint film which is formed by deep-draw is flawless; the paint film is free from dissolution after-tack when soaked in carbon tetrachloride for 2 hours; and the paint film at the position of a notch of the capacitor is free from peeling off and foaming when the capacitor is cooked at the temperature of 100 DEG C for 30 minutes. Accordingly, the coating is wide in application prospect in electronic products.

A process for coloring on the surface of steel band features that the steel band is treated in a heating furnace containing protecting gas at 280-560 deg.C for 2-10 min. Controlling the temp, the flow of protecting gas and time, the yellow, blue, or black color can be obtained.

The invention discloses a high-speed low-shrink low-smoke zero-halogen tight-buffered material used for a 4G optical cable and a preparation method of the high-speed low-shrink low-smoke zero-halogen tight-buffered material. The tight-buffered material is composed of the following raw materials in parts by weight: 30-60 parts of ethylene-vinyl acetate copolymer, 10-20 parts of linear low density polyethylene, 20-30 parts of high density polyethylene, 10-30 parts of compatilizer, 100-150 parts of filler-type flame retardant, 25-60 parts of synergistic flame retardant, 1-2 parts of silane coupling agent, 2-5 parts of ultra-high molecular weight silicone master batch, 0.5-1 part of amides high-performance lubrication dispersant and 0.2-0.5 part of compound antioxygen through stirring, mixing and extruding steps. The tight-buffered material prepared by elaborate formula selection and processing is low in shrinking percentage, strong in rigidity, high in hardness, high in extrusion molding speed, low in rejection rate and good in high / low temperature cycling resistance. When the tight-buffered material is processed, die orifice stacking and salivation are less, the surface of the optical cable is smooth, fine and particle-free, and the tight-buffered material is easy to peel.
