What does vegetable oil series softener have?

This kind of softener is processed by the natural product of agricultural and forestry products more, including pine tar, rosin, oil cream, tall oil and so on.

1. The dead oil

It is the remains of thousand run pine, the appearance of complex composition of dark brown drill thick liquid, specific gravity of 1.011.06. For the use of a large amount of carbon black natural rubber rubber has a good softening and dispersing effect, increase the viscosity of the rubber material, make the rubber soft and smooth, and anti-coke burning effect, very widely used. It also has a good softening effect on synthetic rubber. Use to pay attention to volatile and moisture content.

2. Rosin

Rosin is a solid yellow to uncovered color in appearance, transparent, hard and brittle. It is made after the distillation of turpentine from turpentine. It is an unsaturated compound, which can promote the aging of rubber materials. Rosin has very good nipping, so it is used for glue slurry and glue material combined with cloth.

Oil of 3.

Ointments are divided into black ointments and white ointments. Black ointment is unsaturated vegetable oil (such as linseed oil, rape oil, etc.) and sulfur in 160-170℃ heating system, specific gravity of 1.08-1.20, the appearance of black brown and slightly elastic solid.

White ointment is a loose white solid obtained by the co-heating of vegetable oil and sulfur chloride with a specific gravity of 1-1.36. Adding oil paste can make the processing performance of rubber material significantly improved, with good calendering, pressing out performance, make the semi-finished product surface smooth, reduce shrinkage, easy to mold after vulcanization. Long dosage has delayed vulcanization, and not aging resistance. White ointment has a greater impact on the physical properties of products than black ointment, so it is not suitable to use it, generally used for making light-colored rubber products.

4. The tall oil

Tall oil is a by-product of papermaking industry. It looks like a brown liquid resin, and its main components are fatty acid and resin acid. It can make the products have good tightness, heat resistance and aging resistance, softening effect is better. It is also used as a softener for rubber regeneration.

5. Lecithin in vegetable oil

The 0.7-0.9% phospholipid component of laiza seed oil was used as feed after it was separated from rape oil. It can be used as a softening agent for rubber instead of oil and pine tar. After analysis, the phospholipid in rape oil contains 62% phospholipid, 32% rape oil, and the rest is water. The softening effect is due to the unsaturated double bond carboxylic group and casein group in the structure. When the water content is less than 1%, it is flowing and suitable for mixing in dense mixer. When the water content is I - 6%, it is plastic and suitable for mixing in open mixer.
