Description
Technical field
The present invention relates to a kind of modified polyvinyl chloride kitchen-toilet plates, 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 modified polyvinyl chloride kitchen-toilet plate, have that density is low, hardness is big, nail-holding ability
Advantage high, water absorption rate is low.
The modified polyvinyl chloride kitchen-toilet plate, is made of the raw material of following parts by weight: polyvinyl chloride SG8 type resin
60-80 parts, 40-60 parts of coarse whiting, 20-40 parts of reclaimed materials, P907-9 parts of foaming control agent, 2.7-2.9 parts of lead salt stabilizer, interior profit
SP-600.5-0.6 parts of lubrication prescription, 0.2-0.3 parts of polyethylene wax, 0.2-0.25 parts of micronized polyethylene wax N-14P, plasticizer
OA60.1-0.15 parts, 0.5-0.6 parts of AC foaming agent of heat release type, 1.2-1.4 parts of heat absorbing type NS-603 foaming agent, fluorescent whitening agent
0.15-0.2 parts, 1-2 parts of rutile；Wherein coarse whiting is using being preceding activated.
The modified polyvinyl chloride kitchen-toilet plate, is made of the raw material of following parts by weight: polyvinyl chloride SG8 type resin 70
Part, 50 parts of coarse whiting, 30 parts of reclaimed materials, P908 parts of foaming control agent, 2.8 parts of lead salt stabilizer, SP-600.55 parts of in-lubricant,
0.25 part of polyethylene wax, 0.23 part of micronized polyethylene wax N-14P, OA60.12 parts of plasticizer, heat release type AC foaming agent 0.55
Part, 1.3 parts of heat absorbing type NS-603 foaming agent, 0.18 part of fluorescent whitening agent, 1.5 parts of rutile；Wherein coarse whiting using preceding need into
Row is activated.
Beneficial effect is:
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.
