Description
Technical field
The present invention relates to a kind of lubricant, more particularly to a kind of preparation method of PVC lubricants.
Background technology
PVC refers to Corvic (Poly Vinyl Chloride) abbreviation PVC.It is a kind of polymerization of vinyl
Material, its material are a kind of amorphism materials.PVC material is frequently added stabilizer, lubricant, auxiliary and added in actual use
Work agent, colorant, impact modifier and other additives.With low flammability, high intensity, resistance to climate variability and excellent geometry
Stability.
The effect of PVC lubricants is the release property for the mobility and product for improving resin in plastic processing, is prevented in machine
In interior or mould defect is produced because of adhesion.Typically it is added in moulding compound or is applied to cavity surface.Conventional lubricants have aliphatic acid
And its esters, long-chain fat hydrocarbon.External lubricant and in-lubricant can be divided into according to the mechanism difference of lubricant.
(1) external lubricant:The compatibility of this lubricant and resin for moulding is poor, therefore is commonly used in processing and forming machinery
Or on mould, it forms a lubricating layer between resin, it is easy to resin flowing and article removal, such as paraffin.
(2) in-lubricant:The compatibility of this series lubricant agent and resin is good, among often mixing resin, reduces the melt of resin
Viscosity, improve its mobility.Such as butyl stearate, lead stearate.Stearates are both good lubricant, are effective again
Stabilizer.
But current various lubricants be not suitable for the quality of production more preferably, the more preferable PVC products of transparency.
The content of the invention
It is an object of the invention to provide it is a kind of suitable for the quality of production more preferably, transparency is more preferable, has fungistatic effect
The preparation method of PVC lubricants.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of preparation method of PVC lubricants, this method comprise the following steps：
1. the raw material of PVC lubricants is put into reactor according to proportioning, under stirring, 120-125 DEG C is warming up to；PVC moistens
Lubrication prescription is made up of raw material as follows in parts by weight：
Mineral oil 50-55
Pure cashew nut oleoresin 6-8
Olein 14-18
Hydrogenated vegetable oil 20-25
Lemon 10-12
Cypress essential oil 20-26
Cetostearyl alcohol 12-18；
Material 2. 1. step feeds intake after heating, under 0.07-0.09Mpa pressure, continues to stir, is to slowly warm up to 140
DEG C, and at a temperature of 140-150 DEG C, insulation reaction 10 hours, obtain faint yellow or transparent flow liquid；
3. the reaction product of step 2. is cooled to 90 DEG C of constant temperature, standby section；
4. the reaction product of step 3., through rotary drum condensation-crystallization microtome, after quality inspection is qualified, packaging.
Pure cashew nut oleoresin makes each component compatibility more preferably in formula, and when PVC product is prepared, PVC is arrived in infiltration
In resin powder, physical-chemical reaction occurs after heated, so that obtained PVC product transparency is more preferable.Pure cashew nut oleoresin
It is commercially available prod with cypress essential oil.Cypress essential oil in formula effectively increases the lubricant under reasonable component proportion and is made
PVC products fungistatic effect, adaptability is extensive.The compounding of cypress essential oil and lemon can improve product transparency and
Fungistatic effect, other components have carried out effective cladding to two kinds of essential oils, so as to avoid loss in process of production.
Preferably, step 2. in, described faint yellow or transparent flow liquid is placed in microwave treater, in microwave
Frequency is 915MHz or 2450MHz, under the conditions of environment temperature is 60~90 DEG C, microwave heating treatment 2~3 minutes.By this
After step process, manufactured PVC lubricant chemistries stability is more preferably.
Preferably, 3. the liquid obtained after microwave heating treatment enters step after activated carbon filters.The step can
To remove the various impurity in raw material, be advantageous to obtain the more preferable PVC product of transparency.
The PVC lubricants that the present invention uses can be effectively improved the physical property of PVC products, and the printing opacity of PVC products is made
Rate and glossiness more preferably and have preferable fungistatic effect, are not easy mouldy discoloration.
