Application of polyethylene wax in various industries
Polyethylene wax is widely used in water-based coating, road paint, plastic dyeing, printing ink, paraffin, plastic processing lubrication and color masterbatch dispersion, etc. Hai Hao xiaobian takes you to see the role of polyethylene wax in these industries.
First, water-based paint
Adding polyethylene wax emulsion to acrylic resin can improve its hydrophilicity, play the role of anti-slip, anti-adhesion and stain resistance. Polyethylene wax can produce synchronous effects such as anti-wear and anti-scratch, and reduce the friction coefficient of the coating surface, so that the sliding tendency is greater than the scratching tendency when the object contacts the coating surface. The dynamic friction coefficient of the coating surface can be greatly reduced when the polyethylene wax powder migrates to the coating surface. Adding polyethylene wax powder into the coating can greatly reduce the tendency of the coating to be polished by friction, so as to maintain the durability of low gloss. Polyethylene wax has obvious extinction properties for polyester coatings. In addition, polyethylene wax also acts as a regulator of the melt level flow of powder coatings.
Second, the paraffin
Polyethylene wax has good compatibility with paraffin wax and microcrystalline wax. As paraffin wax modifier, it can improve the melting point, water resistance, moisture permeability and hardness of paraffin wax. In the production of candles, adding a certain amount of polyethylene wax can overcome the defects of paraffin deformation and overflow, and make the crystallization of the product fine. Overcome its brittleness, so that the hardness of wax products increased, reduced shrinkage; In addition, it can improve the heat resistance and demoulding of candles. In addition, because of its good electrical properties, polyethylene wax can also be used as an insulating wax modifier for capacitors, transformers and other electrical appliances.
Three, color masterbatch
Polyethylene wax has good compatibility with toner, wet paint, easy to aggregate and can infiltrate the paint inside the pore, weaken the cohesion, make the pigment aggregate and under the action of shear force are more likely to be broken, the new generation of particles can also quickly get wetting and protection, which can be used as a variety of thermoplastic resin masterbatch dispersant and filler masterbatch, degradation of lubrication of masterbatch dispersant. In addition, polyethylene wax can also play a role in reducing the viscosity of the system, improve the fluidity, so adding polyethylene wax in the production of masterbatch can improve the production efficiency and yield, stable dispersion effect.
Four, printing ink
Polyethylene wax can be used in polyethylene film, polypropylene film, moisture-proof cellophane, plastic, such as fruit sugar, milk, fruit juice, skin care products, medicine bottles, detergent and food packaging materials and other uses of ink such as offset printing ink, as ink wear agent has a good effect. The particle size of polyethylene wax itself is similar to or slightly larger than the thickness of the ink coating film, so it is exposed outside, reflecting the characteristics of wax scratch resistance and scratch prevention. At the same time, polyethylene wax on the surface of the film can be uniform film, so that the ink surface is protected.
Five, road paint
The polyethylene wax is made into toluene dispersion and added to the paint, and the light is transferred to the surface of the coating film and then to the polyethylene wax powder. Through the refraction and diffusion of the powder, the reflection of the light projected on the surface of the coating film is weakened in the same direction, and then the extinction effect is achieved. Different particle size and varieties of polyethylene wax, its extinction effect is not the same, in the actual use process, can be adjusted according to the need of its dosage.
Six, plastic dyeing
As a pigment dispersant for plastic dyeing, polyethylene wax has the characteristics of good compatibility with plastic and heat resistance, good mixing with pigment and easy crushing, and does not affect the color of the end products. Polyethylene wax can also make the surface of pigment particles with the same charge, based on the principle of same-sex repulsion, particles will not attract or gather each other, and then achieve uniform dispersion of pigments.
