Description
Technical field
The present invention relates to technical field of injection molding, specifically a kind of polyurethane corner material reuse method.
Background technology
Polyurethane material is the abbreviation of polyurethanes, and English name is polyurethane, and it is a kind of macromolecule
Material, the species that polyurethane includes is a lot.It is at present directly to abandon to the treatment of polyurethane corner material, and polyurethane is with being difficult
The property of decomposition, polyurethane is difficult to decompose under natural environment, and severe contamination is caused to environment.If corner material be not processed
Treatment is added directly into raw material, then the mechanical property of mixed polyurethane product can be caused unstable, can thus be made
Into unstable product quality.
The content of the invention
In order to solve the above technical problems, the present invention provide it is a kind of mainly for casting type polyurethane elastomer recycle
Polyurethane corner material reuse method, is the recycling to polyurethane elastomer.
The present invention is achieved through the following technical solutions：A kind of polyurethane corner material reuse method, comprises the following steps：
1. polyurethane corner material is collected, eliminating impurities in corner material are clean；
2. the oil stain spot on corner material surface is removed；
3. corner material is milled into powder, granularity is less than 60 mesh；
4. it is more than 24 hours in 80-100 degrees Celsius of environment corner material powder to be put into and be placed on temperature；
5. after being sufficiently mixed the corner material powder after heating and raw material, cast product is carried out；Wherein, by mass, angle
Feed powder end is 0.03-0.05 with the proportioning of raw material：1.
The beneficial effects of the invention are as follows：Polyurethane corner material is recycled, resource utilization is improved, improves economical
Benefit；Reduce the destruction pollution to environment.
Specific embodiment
The following is a specific embodiment of the invention, existing the present invention will be further described.
Material of the present invention is mainly used in vibration sieve plate.For vibration sieve plate, two parts, one are broadly divided into
It is the part contacted with material in screening, referred to as working portion to divide, and with the carrying out of screening, working portion can constantly grind
Consumption, until having ground completely, indicates sieve plate end-of-life, therefore this portion of material is higher to the requirement of the performance indications such as wearability;Separately
A part is the installation coupling part of sieve plate, referred to as mounting portion, and this part is mainly play a part of to install fixed screen deck, is not involved in
Screening materials carrying is contacted, therefore this portion of material adds the raw material of mixed-powder to the performance indications such as tensile strength requirement higher
It is the mounting portion for being cast in sieve plate, and the working portion of sieve plate is still using the raw material for being not added with powder.
Embodiment one
Polyurethane corner material reuse method of the present invention, comprises the following steps：
1. polyurethane corner material is collected, eliminating impurities in corner material are clean；
2. the oil stain spot on corner material surface is removed；
3. corner material is milled into powder, granularity is less than 60 mesh；
Specifically：Corner material is first put into rubber crushing machine the particle for being broken into particle diameter 3-5mm or so, then particle is put into rubber
It is milled in flour mill, milling needs to be divided into 3-5 steps to be carried out, and particle is ground step by step, until powder size is less than 60 mesh；
4. corner material powder is put into and is placed in the environment that temperature is 100 degrees Celsius more than 24 hours；
Specifically：The powder that will be ground is put into constant temperature drying box and heats, and stirs once powder every 8 hours, makes up and down
Layer powder complete exchange；
5. after being sufficiently mixed the corner material powder after heating and raw material, cast product is carried out；Wherein, by mass, angle
Feed powder end is 0.03 with the proportioning of raw material：1.
Now to using the product and original product obtained by polyurethane corner material reuse method（The raw material system of corner material powder is not added
Into）Contrasted, be original product performance test table as shown in table 1：
Table 1
As shown in table 2, it is performance test table using the product obtained by polyurethane corner material reuse method：
Table 2
By the performance comparison of Tables 1 and 2, it can be seen that both performances differ very little, can meet mechanical property completely
It is required that some positions of part or part use, for example：The main working parts of vibration sieve plate, that is, connect when sieving with material
Tactile part, using powder stock, rather than working portion is not added with, i.e., does not participate in directly screening part, and peace is mainly played in this part
The effect of fixed screen deck is filled, it is relatively low to material wear ability requirement, as long as tensile strength disclosure satisfy that, superincumbent material
Two kinds of material difference very littles in 10% tensile strength data can be can be seen that in table, fully meet demand.The present invention passes through corner material
Recovery and utilization technology, improves resource utilization and economic benefit, reduces the destruction pollution to environment.
Embodiment two
Polyurethane corner material reuse method of the present invention, comprises the following steps：
1. polyurethane corner material is collected, eliminating impurities in corner material are clean；
2. the oil stain spot on corner material surface is removed；
3. corner material is milled into powder, granularity is less than 60 mesh；
Specifically：Corner material is first put into rubber crushing machine the particle for being broken into particle diameter 3-5mm or so, then particle is put into rubber
It is milled in flour mill, milling needs to be divided into 3-5 steps to be carried out, and particle is ground step by step, until powder size is less than 60 mesh；
4. corner material powder is put into and is placed in the environment that temperature is 80 degrees Celsius more than 32 hours；
Specifically：The powder that will be ground is put into constant temperature drying box and heats, and stirs once powder every 8 hours, makes up and down
Layer powder complete exchange；
5. after being sufficiently mixed the corner material powder after heating and raw material, cast product is carried out；Wherein, by mass, angle
Feed powder end is 0.05 with the proportioning of raw material：1.
