Description

A kind of preparation method of polyvinyl chloride kitchen-toilet plate
Technical field
The present invention relates to a kind of preparation methods of polyvinyl chloride kitchen-toilet plate, belong to polyvinyl-chloride plate material technical field.
Background technique
In recent years, with the development of economy, government also increasingly payes attention to environment.It is energy saving, green that country advocates exploitation energetically Color product, PVC are a kind of energy-saving environment-friendly products.Therefore, promote and apply PVC product be economize on resources, energy saving, " with modeling The important measures of Dai Mu ", " mould Dai Gang ".Wherein, PVC board the processing performances such as can saw, can follow closely, can dig, can glue due to having, and And have the characteristics that waterproof, fire prevention, Anti-moth-eating, alkaline-resisting, anti-corrosion, sound insulation, have preferable stability and weatherability, it has obtained very well Development, be widely used in furniture-plates, building panel, billboard etc..
For PVC kitchen-toilet plate, the problem in production is that density is done to get off, and plate embrittlement easy fracture, surface hardness is low, is inhaled Water rate is excessively high, and nail-holding ability is low, and the higher production of production cost is unstable.Factory formula and technique initialization are also as production is continuous Change debugging does not accomplish that stable unified production, existing formula composition are complex on a large scale.
Summary of the invention
The purpose of the present invention is to provide a kind of preparation method of polyvinyl chloride kitchen-toilet plate, have that density is low, hardness is big, holds Follow closely the advantage that power is high, water absorption rate is low.
The preparation method of the polyvinyl chloride kitchen-toilet plate, comprising the following steps:
Material is returned according to reclaimed materials-plasticizer-Corvic-coarse whiting-regulator-Corvic-coarse whiting- The sequence of rewinding successively puts into the mixed pot of heat, and remaining small powder, 10-12min is added in stirring heating 30-40min to temperature after being 100 DEG C After stirring is warming up to 120 DEG C, 3-5min is cooled to 60-70 DEG C, and 10-20min is cooled to 40-50 DEG C, then that cooling material is defeated It send to extruder, so that it is plasticized good transportation to mold through the heating of barrel screw rod, control temperature, pressure in mold and squeeze out, via fixed The cooling pressing of type platform is qualitative, and dragger moves out to obtain finished product.
The extruder is the extruder for removing included vacuum system.
Compared with prior art the beneficial effects of the present invention are:
The prior art produces polyvinyl chloride kitchen-toilet plate using extruder, and extruder carries vacuum system, the kitchen-toilet plate of production Material is loose, and water absorption rate is high, this is always the insoluble a great problem of the industry.The present invention is by adjusting proportion scale, mixing Material sequence and improve equipment (vacuum system for removing extruder), not only greatly reduce the water absorption rate of plate, and make kitchen Defending plate water absorption rate can freely be controlled by adjusting proportion scale.
On the one hand the present invention is fed by segmented mode guarantees being sufficiently mixed for raw material, on the other hand play to part material Modifying function greatly increases the compatibility between each raw material, to improve the processing performance and production stability of raw material, Jin Erti High yield quality.Meanwhile the temperature and time of strict control subsection charging, immediate effervescence is avoided, is slowly carried out with guaranteeing to react, Guarantee that the bubble generated is mostly uniformly fine and closely woven, plate can coat bubble completely, prevent the appearance of abscess, absciss layer, string bubble, material The frequency of occurrences of plate interior void can be reduced when extrusion molding without using vacuum system, and it is loose to avoid plate, Substantially reduce kitchen-toilet plate water imbibition.
The present invention by reducing the dosage of regulator, technique and foaming system it is close with the use of product is significantly reduced Degree, substantially reduces production cost；The quality of product is greatly improved by adjusting proportion scale and mixing sequence in the present invention, The plate surface hardness of production, water absorption rate, nail-holding ability are all substantially better than the prior art.
