What are the application industries of polyethylene wax?
1. Water-based paint
Adding polyethylene wax emulsion to acrylic resin can improve its hydrophilicity and play the role of anti-slip, anti-adhesion and stain resistance. Polyethylene wax can produce synchronous effects such as anti-wear and anti-scratch, reduce the friction coefficient of the coating surface, and make the sliding tendency greater than the scratching tendency when the object touches the coating surface. The migration of polyethylene wax powder to the coating surface can greatly reduce the dynamic friction coefficient of the coating surface. The addition of polyethylene wax micropowder to the coating can greatly reduce the tendency of the coating film to be polished by friction, thereby maintaining low gloss durability. Polyethylene wax has obvious matting properties for polyester coatings. In addition, polyethylene wax also acts as a modifier for the horizontal flow of the powder coating melt.
Polyethylene wax has good compatibility with paraffin and microcrystalline paraffin. As a paraffin modifier, it can improve the melting point, water resistance, moisture permeability and hardness of paraffin. In the production of candles, adding a certain amount of polyethylene wax can overcome the shortcomings of paraffin deformation, overflow, etc., and make the crystal of the product thin; overcome its brittleness, increase the hardness of the wax product, and reduce the shrinkage; in addition, it can improve the Heat resistance and mold release of candles. In addition, due to the good electrical properties of polyethylene wax, it can also be used as an insulating wax modifier for electrical appliances such as capacitors and transformers.
Polyethylene wax has good compatibility with toner, it is easy to wet the pigment, and can penetrate into the internal pores of the pigment agglomerate, weaken the cohesion, make the pigment agglomerate more easily broken under the action of external shear force, and the newly generated particles It can also be quickly wetted and protected, so it can be used as a dispersant and filler masterbatch for a variety of thermoplastic resin masterbatches, and as a lubricant and dispersant for degraded masterbatches. In addition, polyethylene wax can also reduce the viscosity of the system and improve the fluidity. Therefore, adding polyethylene wax during the production of color masterbatch can improve production efficiency and output, and stabilize the dispersion effect.
4, wax for printing ink
Polyethylene wax can be used in polyethylene film, polypropylene film, moisture-proof cellophane, plastics, etc. It is used in packaging materials for fruit candy, milk, juice, skin care products, medicine bottles, detergents and food, and other inks such as offset printing inks, etc. Among them, it has a very good effect as an ink anti-wear agent. The particle size of polyethylene wax itself is similar to or slightly larger than the thickness of the ink coating, so it is exposed to the outside, reflecting the scratch resistance and anti-scratch characteristics of the wax. At the same time, polyethylene wax can evenly form a film on the surface of the coating film, so that the surface of the ink can be protected.
The polyethylene wax is made into a toluene dispersion and then added to the paint. The light migrates to the surface of the coating film and then to the polyethylene wax powder. Through the refraction and diffusion of the powder, the light projected on the surface of the coating film is directed to the same direction. The reflection of the direction is weakened, and then the matting effect is achieved. Different particle sizes and varieties of polyethylene wax have different matting effects. In actual use, the dosage can be adjusted according to needs.
6, wax for plastic dyeing
As a pigment dispersant for plastic dyeing, polyethylene wax has the characteristics of good compatibility with plastics and heat resistance, good mixing with pigments, easy to crush, and does not affect the color of end products. Polyethylene wax can also make the surface of the pigment particles carry the same charge. Based on the principle of repulsion of the same sex, the particles will not attract or aggregate each other, so as to achieve uniform dispersion of the pigment.
