The invention relates to an oil repellent finish of a domestic textile. Each liter of the oil-resisting finishing agent of a fabric contains the following components by weight: 30-50g of acrylic acid fluorocarbon ester resin, 1-3g of thickening agent, 3-5g of water soluble organic silicon, 0.9-2.5g of triethylamine and the balance of water. The invention is mainly used for the post-treatment of superfine fibre, resin containing fluorine forms a layer of protective film on the surface of the superfine fibre or a xuenierquanli carpet after a superfine fibre product is treated by the functional processing of the invention, and dirt can not infiltrate into the inside of the fibre but is coated by the surface of the fibre; thus, an oil repellent function is achieved. The invention has the superior functions of oil resistance and easy decontamination, and a processed product has flexible hand feel.

The present invention provides a luminous pavement material, which includes a surface material and a base material in sequence from top to bottom, wherein the base material includes the following components in parts by weight: 120-240 parts of cement; 10 parts of recycled micropowder from construction waste ‑70 parts; 500‑900 parts of recycled coarse aggregate from construction waste; 200‑600 parts in recycled fine aggregate from construction waste; 60‑140 parts in water; The following components: 120-240 parts of white cement; ≤80 parts of coloring powder; 200-600 parts of recycled fine aggregate from construction waste; 60-140 parts of water; ≤6 parts of water reducing agent. The present invention further provides a luminescent road surface. The invention provides a luminous pavement and a preparation method thereof. Construction waste is used to make a luminous art road. Luminous aggregates and brick aggregates can be inlaid according to a certain pattern. After being polished, it has an artistic effect, and the appreciation effect is better at night.

The invention discloses a method and application for preparing cement floor color paste and cement solidification enhancer from dye residue. The method comprises the following steps: using dye residue to prepare mother liquor; mixing 70-85 parts by weight of mother liquor, polyether polyol 2~6 parts by weight, 2~8 parts by weight of triethanolamine, 6~10 parts by weight of lithium silicate, 3~10 parts by weight of urea and 3~10 parts by weight of diethylene glycol are mixed together and stirred evenly, and the stirring time is After 60 to 120 minutes, the cement floor color paste and cement curing enhancer are obtained, which are sealed and stored. If the specific gravity value of the dye residue is 1.15-1.17, it is used as mother liquor; if the specific gravity is lower than 1.15-1.17, the following steps are included: extracting polyacrylamide by 0.5-2% of the weight of the dye residue, adding an appropriate amount Dilution water dissolves polyacrylamide into a solution, the solution is added to the dye residue and stirred, then precipitated, and the upper part of the liquid close to water is removed, and when the specific gravity reaches 1.15~1.17, it is used as the mother liquor. The invention has the beneficial effects of simple method, convenient processing, effectively solving dye discharge and beautifying buildings.

The invention belongs to the technical field of high polymer materials and discloses a thermo-crosslinking type thermoplastic polyurethane elastomer, a preparation method and an application thereof. The thermo-crosslinking type thermoplastic polyurethane elastomer comprises the following components by mole fraction: 1.0 part of hydroxy-terminated butadiene rubber, 2.2-8.8 parts of p-phenylenediisocyanate, 1.1-7.5 parts of terephthalyl alcohol and 0.003-0.025 part of diisopropyl ditert-butyl peroxide. The thermo-crosslinking type thermoplastic polyurethane elastomer provided by the invention isprepared according to the following steps: adopting a prepolymer method for preparing a prepolymer from reaction of hydroxy-terminated butadiene rubber and p-phenylenediisocyanate; adding vulcanizingagent diisopropyl ditert-butyl peroxide; mixing the prepolymer containing vulcanizing agent with terephthalyl alcohol, and then curing, thereby acquiring the thermo-crosslinking type thermoplastic polyurethane elastomer. The thermo-crosslinking type thermoplastic polyurethane elastomer provided by the invention has excellent low temperature resistance, high temperature resistance, mechanical properties and oil resistance, and can be used for preparing oil pipes and hydraulic and pneumatic sealing elements.
