Abstract

The invention discloses a PVC compound which produces 0.03mm to 1.5mm hard piece and semi-hard piece sheets through a rolling method. The compound is characterized in that good toughness effect is achieved through the combination of PVC with different polymerization degree without impact modifier, and largely saves cost; the elasticity and physical property of the obtained PVCD compound are equalto that got by using the impact modifier, the granulation and flow mark are basically removed, and the light transmittance is better; therefore, the compound is applicable to relevant industries, such as shrinked plastics, blow molding, printing, gluing, etc.

Description

Technical field: [0001] The invention relates to a polyvinyl chloride composition, in particular to a polyvinyl chloride composition for producing sheets by calendering. Background technique: [0002] In industries such as blister molding, blow molding, printing, gluing, etc., conventional polyvinyl chloride (PVC) compositions for producing sheets by calendering include PVC, stabilizers, processing aids, impact modifiers, lubricants (outside slip agent or internal slip agent), plasticizers, calcium powder, etc. can also be added. When making hard PVC sheets, to change the notch sensitivity of hard PVC and improve the toughness of hard products, it is necessary to add a semi-compatible, low-modulus substance with PVC-impact modifier. However, impact modifiers are expensive, so it costs more to obtain a tougher PVC composition. Invention content: [0003] The object of the present invention is to provide a PVC composition which can achieve at least no less effect than the ...
