Preferably, the raw material that described PVC foam body uses also includes PVC powder, plasticizer and colorant, and quality proportioning For:
PVC powder 0-50 part
Plasticizer 0-50 part.
Preferably, during PVC powder is polyvinyl chloride resin, PVC emulsifying powder, PVC copolymer resin one or more.
Preferably, during plasticizer is DOTP, tributyl 2-acetylcitrate one or both.
Preferably, during foaming agent is azodicarbonamide, sodium bicarbonate one or both.
Preferably, one during stabilizer is solid calcium zinc composite stabilizer, Liquid K zinc composite stabilizer, epoxy soybean oil Or it is several.
Preferably, one or more during lubricant is Tissuemat E, glyceryl monostearate, stearic acid.
The present invention also provides for the manufacture method of a kind of PVC foam body, and described manufacture method comprises the following steps,
(1) by proportioning, raw material is mixed；(2) planetary extruder plasticizing is used；(3) filter；(4) expanding；(5) calendering；(6) send out Bubble；(7) cooling and shaping.
Preferably, step (6) is carried out in foaming furnace, and the temperature of foaming furnace is at 180 ~ 220 DEG C.
Preferably, in step (7) a metallic, cooling medium be water or/and gas, the temperature of cooling medium is 20-40 DEG C.
Due to the employing of above technical scheme, the present invention compared with prior art has the advantage that
The present invention makes full use of the leftover pieces of PVC foam, cost-effective, reduces and pollutes.With planetary extruder replace banbury and Extruder, saves molding time, and energy consumption is low, and yield is high.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further details.Should be understood that these embodiments are for saying The ultimate principle of the bright present invention, principal character and advantage, and the present invention is not limited by the scope of following example.Embodiment is adopted Implementation condition can do further adjustment according to specific requirement, not marked implementation condition is usually the bar in normal experiment Part.
Below in conjunction with concrete case, patent of the present invention is further described in detail.
Embodiment 1
The quality proportioning of raw material is:
PVC reclaimed materials 100 parts；Azodicarbonamide 4 parts；Calcium-zinc composite stabilizing agent 5 parts；Stearic acid 0.2 part；Tissuemat E 0.2 Part；SG5 type PVC powder 5 parts；DOTP(DOTP) 5 parts；Black masterbatch 2 parts.
Embodiment 2
The quality proportioning of raw material is:
PVC reclaimed materials 100 parts；Azodicarbonamide 3 parts；Sodium bicarbonate 2 parts；Calcium-zinc composite stabilizing agent 4 parts；Glyceryl monostearate 0.3 part；Tissuemat E 0.2 part；Black masterbatch 2 parts.
Embodiment 3
The quality proportioning of raw material is:
PVC reclaimed materials 100 parts；Foaming agent 5 parts；Stabilizer 10 parts；Lubricant 1 part, PVC powder 50 parts；Plasticizer 50 parts.
Embodiment 4
The quality proportioning of raw material is:
PVC reclaimed materials 50 parts；Foaming agent 1 part；Stabilizer 2 parts；Lubricant 0.1 part.
In above-described embodiment, PVC reclaimed materials is the leftover pieces compound after crushed of PVC foam material.
The manufacture method of foaming body, (1) mixes in raw material putting into high-speed mixer by proportioning；(2) by step (1) The material of gained puts into planetary extruder and plastifies, and uses planetary extruder to plastify.Due to the PVC feed back density used Low, the charging system of planetary extruder is to force feeding device, can have sufficiently large charging rate, can prevent appearance in hopper Arch formation, and force to have bottom feeding device chiller, PVC feed back can be avoided to be burnt decomposition in feeding device； Material is in plasticizing process, and the center bolt of rotation drives planetary-screw rotation, makes material melts plastify, and screw rod and machine barrel Gap between internal tooth, at 0.2-0.4mm, makes material dispersion evenly, and plasticizing efficiency is high.During plasticizing, each district of planetary extruder Temperature is at 140-160 DEG C, and extrusion rotating speed 30-50 turns/min.Preferably, the rotating speed 35r/min of planetary extruder, extrusion temperature 155 DEG C, feeding section has adsorbent equipment, the metallics in absorption batch mixing.(3) material of step (2) gained is put into filter Filter；(4) material of step (3) gained is put into expanding mould and carry out expanding；(5) material of step (4) gained is thrown Rolling in entering calender, control thickness 2mm, calender is two-roll calendar or tri-roll press machine；(6) by step (5) institute Material put into dry type stove of firing and foam, foaming furnace each district temperature is at 180-220 DEG C, and hauling speed is 1-15m/min, Preferably, blowing temperature 190 DEG C, hauling speed 5m/min, stove of firing is open stove of firing；(7) by the thing of step (6) gained Material puts into cooling chamber and carries out cooling and shaping, the product thickness obtained about 10mm, hardness about 30HD, and density about 0.35 g/cm3 makes Cooling medium be in water, gas one or both combination, it is ensured that cooling and shaping temperature is at 20-40 DEG C, it is preferable that cooling be situated between Matter is the air of 25-30 DEG C；(8) material of step (7) gained is carried out rolling according to specification.
The present invention makes full use of the leftover pieces of PVC foam, cost-effective, reduces and pollutes.Banburying is replaced with planetary extruder Machine and extruder, save molding time, and energy consumption is low, and yield is high.
