Abstract
The present invention provides a kind of preparation methods of the plastics for bath product, high density polyethylene (HDPE), low density polyethylene (LDPE), plasticizer, catalyst, active heat filling, antioxidant, polytetrafluoroethylene (PTFE) and polystyrene are mixed in three times, then mixture is put into double screw extruder and is squeezed out.Hardness of the present invention is high, and service life is long, commercially valuable.
Description
Technical field
The present invention relates to plastic production technology field, the preparation method of specifically a kind of plastics for bath product.
Background technology
Plastics are to pass through high-molecular compound made of addition polymerization or polycondensation polymerized using monomer as raw material
(macromolecules), it is commonly called as plastics (plastics) or resin (resin), can freely change ingredient and body styles,
It is made of the additives such as synthetic resin and filler, plasticizer, stabilizer, lubricant, colorant.
The main component of plastics is resin.This noun of resin is initially the lipid secreted out of by animals and plants and gains the name, such as
Rosin, shellac etc., resin refer to the high-molecular compound not yet mixed with various additives.Resin accounts for about plastics total weight
40%~100%.The basic performance of plastics depends mainly on the person's character of resin, but additive also plays an important role.Some plastics
It is substantially made of synthetic resin, is free of or contains less additive, such as organic glass, polystyrene.
The plastic products in bath product based on high density polyethylene (HDPE) are widely used at present, and high density polyethylene (HDPE) is often
Hardness is poor, is easily damaged, and service life is short.
Invention content
The present invention in order to solve problems in the prior art, provides a kind of preparation method of the plastics for bath product,
Hardness is high, and service life is long, commercially valuable.
The present invention includes the following steps：
1) 65 parts -80 parts of high density polyethylene (HDPE), 5 parts of -10 parts of low density polyethylene (LDPE)s and 5 parts of -10 parts of plasticizer are weighed, is mixed
It is heated to 150-200 DEG C；
2）1 part of -2 parts of catalyst, 1 part -2 parts active heat fillings, 0.1 part of -1 part of antioxidant, 5 are added at the uniform velocity into mixture
- 10 parts of polytetrafluoroethylene (PTFE) of part, addition time are 10-15min；
3）Mixture is warming up to 300 DEG C, then adds 10 parts of -20 parts of polystyrene into mixture；
4）It is put into double screw extruder extrusion, screw speed is 100-200 revs/min.
It is further improved, the catalyst is platinum catalyst.
It is further improved, the active heat filling is Alpha-alumina.
Advantageous effect of the present invention is：Hardness is high, and service life is long, commercially valuable.
Specific implementation mode
The invention will be further described below.
The present invention includes the following steps：
1) 65 parts -80 parts of high density polyethylene (HDPE), 5 parts of -10 parts of low density polyethylene (LDPE)s and 5 parts of -10 parts of plasticizer are weighed, is mixed
It is heated to 150-200 DEG C；
2）1 part of -2 parts of catalyst, 1 part -2 parts active heat fillings, 0.1 part of -1 part of antioxidant, 5 are added at the uniform velocity into mixture
- 10 parts of polytetrafluoroethylene (PTFE) of part, addition time are 10-15min；
3）Mixture is warming up to 300 DEG C, then adds 10 parts of -20 parts of polystyrene into mixture；
4）It is put into double screw extruder extrusion, screw speed is 100-200 revs/min.
It is further improved, the catalyst is platinum catalyst.
It is further improved, the active heat filling is Alpha-alumina.
There are many concrete application approach of the present invention, the above is only a preferred embodiment of the present invention, it is noted that for
For those skilled in the art, without departing from the principle of the present invention, it can also make several improvements, this
A little improve also should be regarded as protection scope of the present invention.
