1. Features: beautiful color, strong coloring power, high purity, resistance to strong sunlight exposure, resistance to atmospheric influences, resistance to dirty gases and various climate changes. Good alkali resistance and poor acid resistance. The coating power of rubber products is quite large. It will react in hot sulfuric acid when exposed to sunlight, air, acids and alkalis, and will not change when it is encountered with sulfur or hydrogen sulfide. Stability requires that the processing temperature is not critical in the molding process. For asbestos plastic products such as brake pads and brake plates can increase the friction coefficient and reduce friction loss. Economical in use.
2. Uses: Iron oxide pigments for rubber can be applied to the following various rubber products.
Various inner tube products: car inner tube, aircraft wheel inner tube, bicycle and rickshaw bark tire, etc.
Model products: soles, heels, corks, hot water bottles, gloves, ball tires, rubber tiles, etc.
Hard products: chemical materials, insulating materials, battery tanks, medical appliances, stationery products, etc.
Others: tubes, belts, purses, wires, waterproof raincoats, etc.
Iron oxide pigments for plastics are suitable for coloring the following plastic products.
Thermosetting plastics: urea-formaldehyde plastics, melamine resin plastics, phenolic plastics, foam plastics, asbestos plastics (brake pads, brake pads, etc.) products.
Thermoplastics; polystyrene plastics, polyvinyl chloride plastics (colored films, plastic
Board), polyethylene molding compound, etc.
3. Method of use: Use of iron oxide pigments on rubber: Generally, after washing and refining raw rubber, mechanical treatment is used to obtain the necessary plasticity, and then vulcanizing agent and iron oxide pigments, zinc oxide, calcium carbonate and other fillers are added Carry out the control to obtain the raw rubber. Then process and shape various rubber parts.
How to use iron oxide pigments on plastics? such as asbestos plastic brake pads
Products, resin, asbestos, iron oxide pigments(such as iron oxide red 130, iron oxide yellow 313) are mixed together, kneaded and dried after adjusting a certain viscosity with a solvent, and then taken asbestos plastic into press I to form, that is, wood grain decorative paper iron oxide pigment is used for Coloring method of polyvinyl chloride plastic: firstly mix iron oxide pigment and plasticizer (di-zinc phthalate, etc.) into a thick paste (the dosage is divided into 2: 1, 1 1.1, l: o.5, etc.), put it on a flat roller machine or a three-roller machine (with transparent film and opaque film), and then blend the components and color paste evenly according to the formula of the transparent or opaque film until no color yarn or color point is produced , Yingli. Put this colored polyvinyl chloride paste in the applicator, and spread it on the glass plate evenly, after standing still, draining and defoaming. Put it in a 180 ° C blower oven for plasticization, take it out after 10 minutes and cool it to form a colorless or colored PVC film.
4. Application: In the application of rubber and plastics, iron oxide red with no heavy metal ions such as copper and manganese can be used in aviation tires to prevent the aging of rubber. Iron oxide pigment has the characteristics of strong coloring power and pure color. It is used as a coloring agent and filler in PVC plastic floors, PVC colored films, in thermosetting plastics such as electric jade powder, bakelite powder, and polyolefins. Thermoplastics can be used: iron oxide pigments, such as masterbatch or slurry preparation, will be more popular in the industry. Because iron oxide pigments are non-toxic, transparent iron oxide pigments are used abroad for the coloring of plastic beer bottles, pharmaceutical vials, and food packaging plastics. It is a new type of pigment used in plastics.
