The invention relates to water-based system reflective pulp. The environment-friendly water-based reflective pulp low in pollution is prepared from components as follows: 0.6%-1.0% of a mixture of cyclosiloxane and organic amine, 0.6%-1.0% of aromatic polyglycol ether, 4.0-6.0% of urea, 1.0%-2.0% of acrylate, 11%-20% of an aqueous PUA binder, 7.0%-13% of glass beads and the balance of deionized water. The glass beads with the size of 10 microns can be applied to the sportswear fabric. After the water-based system reflective pulp is printed on the sportswear fabric, the effect of sportswear fabric reflective patterns required individually is realized, the reflective pulp has the effects of soft texture, high elasticity and high retroreflective coefficient and is resistant to multi-time washing, and reflective printing has richer expression effects.

The invention discloses a scraping-type two-component road marking paint and a preparation method thereof, relating to the technical field of transportation paints, comprising A component with a mass fraction of 57.45% and a B component with a mass fraction of 42.55%. The components are formulated according to the following mass fractions: 45-55% of modified epoxy resin, 5-10% of pigment, 35-40% of filler, 0.5-1% of auxiliary agent, and 0.2-0.7% of thixotropic agent; the B group According to the following mass fraction formula: 30-40% epoxy curing agent, 10-15% pigment, 50-55% filler, 0.5-1% additive, 0.2-0.7% thixotropic agent; the A component and Component B is uniformly mixed according to the mass ratio of 1‑1.5:1. The scraping type two-component epoxy marking paint produced by the invention has strong adhesion to road surfaces and glass beads, good wear resistance and water resistance, long service life, low maintenance cost, high solid content, and is healthy for construction workers. No impact, fast curing.

The present invention involves a reflective ink and its preparation methods, tobacco paper and its preparation method.15 copies; 0.5 to 3 copies of wetting dispersions; 0.2 to 2 copies of anti -sinking auxiliary agent; 30 to 60 solvents.

The invention relates to a thermosensitive type light reflection film capable of being jet printed, and belongs to the technical field of reflecting materials. The existing problem that high retro-reflecting coefficient and jet printing can not be achieved simultaneously is solved, the light refection film comprises a thermosensitive adhesive layer and a resin layer which are overlapped in sequence from top to bottom and fixed, multiple grooves are formed in the upper portion of the resin layer, each groove is internally embedded with a glass bead, a reflecting layer is laid between a groove wall of each groove and the corresponding glass bead, coatings capable of being jet printed are arranged on the upper surface of the resin layer, and the upper portion of each glass bead is higher than the corresponding coating capable of being jet printed. The thermosensitive type light reflection film capable of being jet printed has a better jet printing effect, and the double-effect of higher retro-reflecting coefficient is achieved. The coatings capable of being jet printed between each two glass beads are designed to be shaped like a sunken arc surface, so that the effect that the retro-reflecting coefficient is greater than 400 cd.lx<-1>.m<-2> is achieved.

Provided is a microprism reflecting material manufacturing method, comprising employing the diamond lathe ultra-precision cutting process to manufacture a microprism structure reflecting material original graphic mould on materials such as plastic, metal, colloid, crystal, etc.; manufacturing modules of PDMS, PC, PMMA, photosensitive gel, etc. out of an original mould with a microprism pattern through thermocuring, ultraviolet curing, and duplication processes; plating a duplicated intermediate mould with a layer of fluorine containing macromolecules, and improving nickel mould surface demoulding; coating the modified intermediate mould with material solutions of PMMA, PC, photosensitive gel, etc. to perform curing processing, and then performing separated demoulding between the module and a target reflective membrane; and finally decorating the demoulded microprism reflecting material membrane into a designed shape. The method effectively solves the problems of great manufacturing difficulty, poor preserving effect, large processing technology tolerance, etc. of a present microprism reflecting material intermediate work mould.

This invention discloses a kind of regression reflect fabric, including one reflection component, a metal reflection layer, a adhesive layer and one basic material, the reflection component layer is implied 30-130 grams of tiny glass beads with each square arranged intensively. The fabric's reflection function is good, the anti-coefficient can amount to the 70-700 cds / Lx / square m.

This application relates to a high-efficiency retroreflective hot-melt road marking and its production method, including the following steps: S1: heating the marking paint to 180-220 °C, stirring evenly, and keeping it warm for 5-10 minutes; S2: maintaining the temperature at 180-200 ℃ temperature, at 0.3~0.35kg / m 2 Sprinkle glass beads on the surface of the marking paint; S3: maintain the temperature of 180~190°C, discharge the material, and obtain high-efficiency retroreflective hot-melt highway markings. The markings prepared by this application have a high retroreflection coefficient, And it has good reflectivity in rainy nights, and it also has high wear resistance, water resistance and alkali resistance, which can achieve a long-lasting reflective effect.

The invention provides an internally cross-linked modified acrylic emulsion and a water-based coating containing the same, wherein the polymerizable monomers in the acrylic emulsion include epoxy vinyl monomers, ethyleneimine, acrylic acid and methacrylic acid ester. The marking paint is non-toxic, harmless, non-polluting, has good adhesion, has good reflective performance at night and in rainy days, is durable, wear-resistant, weather-resistant, skid-resistant, fast recoatable and suitable for industrial production.
