Abstract

The invention relates to the production of antistatic finishing decorative materials based on PVC and can be used in the industry of polymeric building materials and light industry. The invention allows for an order to improve the antistatic properties of materials and to increase by 25-50% the processability and thermal stability of PVC of the face layer due to the additional introduction of the same antistatics into the layer of printed pattern of the face layer in PVC in a quantitative ratio by mass 1, 0:: (1.94-3.35), respectively, with a total content of the antistatic agent - in the material 2.0-2.8 wt.%. At the same time, the layer of printed pattern is made on the basis of vinyl chloride homo- or copolymer. 1 tab. (C (L

The invention relates to the field of producing antistatic finishing decorative materials based on polyvinyl chloride (PVC) and can be used in the industry of poly WepHbix building materials and light industrial materials.

The aim of the invention is to improve the antistatic properties of the material, processability and thermal stability of the composition of the front layer.

For the manufacture of the material, polyvinyl chloride (PVC) dioctyl phthalate (LOF), hydrophobic chalk, titanium whitewash, ocher, stabilizers from barium and cadmium gearates, antistatic agents with | intamid-5, ethoxylated 5 moles of ethylene monomethanolamides, 15 moles of ethylene monomethanamolamides, are used. acids C ,,. , or stea-20 layers are mixed, kneaded, and calanrox-6 is an ester of polyethylene glycol as described. On semi-K0LI and stearic acid, copolymer BA-15, cyclohexanone, ethyl acetate, pigments.

The material is obtained as follows: 25 3 ohms;

Raw materials for the front layer: PVC, DOP,

A printed pattern of a composition containing a BA-15 copolymer, solvents and pigments is applied to the base. Examples 2-8 (according to the proposed method), differ from example 1 in that the composites for the printed pattern further comprise an antistatic agent.

chalk, titanium white, ocher, stabilizer and antistatic agent are loaded into the mixer, where they are mixed for 15-20 minutes. Then the composition is fed to an extruder with temperatures in the zones 1DO-120, 110-130, 110-130, 120-140, 1 30-150 ° C, the screw rotation speed is 20-40 rpm. The extrusion mass is set on rollers, where it rolls 150-160 ° C for 10-15 minutes, and then on caland, p with temperature p to rolls of 140-150, 140-150, 150-160 C.

Composition for the application of printed pattern.  The BA-15 or PVC copolymer, EP-6202-H E 6650H, cyclohexanone, ethyl acetate, pigment and antistatic agent are prepared in a 3: mixer, then frayed on a paint grinder. The pattern on the PVC sheet is deposited using a printing roll and dried at 100-120 ° C for 1-2 minutes. The specific surface resistivity of the material is determined 148 hours after production, the overspeedability of the composition, the face layer - according to the time of milling at the time of color change, and thermal stability - according to GOST. Synergistic effect of the additional introduction of antistatic agent alove comprising a face layer of polyvinyl chloride and a printed pattern layer deposited on it from a composition based on a vinyl chloride homo- or copolymer, consisting in introducing an antistatic agent into the face layer, characterized in that, in order to improve the antistatic properties of the material, processability and thermal stability of the composition of the front layer, the antistatic agent is additionally introduced into the layer of the printed pattern and the ratio of the amount of antistatic agent in the front layer and the layer of the printed pattern is by weight (1.94-3.35): 1.0, respectively; ba layer administered the same antistatic agent at a total sode1 Zhaniya in its material 2,0 2,8 us.%.
