The industries such as office building, market, airport, school, library, gymnasium, pharmaceutical factory, hospital, factory are widely used, and obtain satisfaction
Effect.PVC flooring has environmentally friendly formaldehydeless, fire-retardant, waterproof, mothproof, moistureproof, noise-proofing, cost as ecological floor
It is low the advantages of can be recycled, received by increasing people.
Prior art production PVC flooring is usually that related auxiliaries are added in Corvic, is mixed i.e. through too high
Extrusion molding base material, is then packaging listing, existing formula and production method by following process such as sanding, pad pasting, UV processing
Not only production cost is high for the product of acquisition, and product deposits that heat distortion temperature is low, and sanding bending, thick floor is uneven whole
The problems such as.
The content of the invention
It is an object of the invention to provide a kind of PVC flooring base material, with cost is low, quality is good, high temperature is constant
The advantages of shape, smooth surface-brightening.
The present invention also aims to provide a kind of preparation method of PVC flooring base material.
Described PVC flooring base material, is made up of the raw material of following parts by weight：Polyvinyl chloride SG8 type resins 80-100
Part, 100-120 parts of coarse whiting, 50 parts of floor base material template reclaimed materials, 9037-8 parts of foaming control agent, foaming control agent 9022-3
Part, 2.8-4.9 parts of compound stabilizer, ZB-600.6-1.2 parts of in-lubricant, 0.35-0.7 parts of Tissuemat E, AP 0.2-0.5
Part, OA30.5-0.8 parts of plasticiser, 0.3-0.4 parts of heat release type AC foaming agents, triumphant 1.4-1.6 parts of c-2 foaming agents, iron in heat absorbing type
2-5 parts of bloom, 2-4 parts of CPE.
The preparation method of described PVC flooring base material, comprises the following steps：
(1) batch mixing：
First by 80-100 parts of polyvinyl chloride SG8 type resins, 100-120 parts of coarse whiting, 2.8-4.9 parts of compound stabilizer is put
0.3-0.4 parts of heat type AC foaming agents, triumphant 1.4-1.6 parts of c-2 foaming agents in heat absorbing type, ZB-600.6-1.2 parts of in-lubricant gathers
0.35-0.7 parts of ethylene waxes, 0.2-0.5 parts of AP, OA30.5-0.8 parts of plasticiser, 2-4 parts of CPE, 2-5 parts of iron oxide yellow powder, foaming is adjusted
9037-8 parts of agent, 9022-3 parts of foaming control agent are saved, 50 parts of floor base material template reclaimed materials is sequentially added in the mixed pot of heat, and stirring rises
Compound is put into stirring in cold mixing pot rapidly to 110-120 DEG C, then and is cooled to 40-60 DEG C by temperature；
(2) plasticizing foaming：
Cooling material is delivered to the extruder that temperature is set as 150-200 DEG C, makes it through seven sections of twin-screw heating of barrel
Plasticizing foaming；
(3) finished product is extruded：
The material plastified after foaming is delivered into the mould that temperature is 160-190 DEG C, die lip is extruded, cools down and presses via shaping platform
Sizing is closed, hauling machine excision forming of moving out obtains finished product；Oil temperature machine temperature is set at 175-190 DEG C, die lip wherein at mould
Water temperature machine is set in 15-30 DEG C, and shaping platform cooling water temperature is 17-30 DEG C.
The batch mixing of the present invention is simple to operate, and the setting range of technological temperature is relatively wide relatively reasonable, reduces in production due to temperature
A variety of operation difficulties that degree setting range is smaller and brings.
PVC flooring matrix density prepared by the present invention is 0.7-0.9g/cm3, thickness is 4.2-5mm.
Compared with prior art, the beneficial effects of the invention are as follows：
Inventive formulation advantages of simple, production cost is low, by adding appropriate calcium powder on the basis of panel density is improved
It ensure that plate surface finish.
Add polymeric plasticizer CPE be haloflex, due to the presence of chlorine atom make CPE turn into polar polymer and
There is identical polar group with polyvinyl chloride, enhance the compatibility with polyvinyl chloride, because that can keep larger between its macromolecular chain
Van der Waals force, therefore the impact resistance of polyvinyl chloride is substantially increased, play good toughening effect.
CPE of the present invention addition maintains 2-4 parts, and CPE consumption is very few, in order to reach good modeling during production sheet material
Change effect, barrel temperature can be greatly improved, and high temperature thickener is easily caused, while product embrittlement, quality dissatisfaction；Consumption conference makes
Too, extrusion is difficult to control to material plasticizing in sheet material production, has considerable influence simultaneously for plate surface hardness.
Because the proportion of calcium powder is larger, the consumption of lubricant is increased, it is to avoid due to lack of lubrication, friction increase, material
The too poor caused a variety of adverse consequences of mobility, the increasing of lubricant quantity also substantially prolongs the production time；But too many
Lubricant can cause material plasticizing impacted again, and mobility causes by force discharging unstable very much, and sheet metal thickness is unstable, and production is difficult to control
System.
The regulation space of temperature control, die orifice regulation, the speed of production of the present invention etc. is larger, is conducive to the stabilization of production to hold
It is continuous.
Product of the present invention is also with high temperature is indeformable, environment friendly and pollution-free, renewable, elastic big, anti-impact force is strong, noise-proofing
With meet water be puckery anti-skidding effect the advantages of.
Product quality of the present invention is light, and density is small, has in skyscraper for building body load-bearing and saving space without comparable
The advantage of plan.
