Description

(54) POLYMER COMPOSITION.

The invention relates to the chemical industry, in particular, to the composition of compositions based on oligoester acrylate (UAE) with vinyl chloride polymers (VH

The composition is intended for nang-, the shed on the surface of any material (metal, wood, plastic, ceramics, etc.). To protect it from the effects of aggressive media (organic solvents, acids, alkalis), including at elevated temperatures without pretreatment of the material with adhesive.

A known polymer composition containing, in wt%: paste-forming PVC 15-85, polymerizable organic compound 0.1-80, plasticizer 0-50, initiator 0-8, stabilizer 0.01-4, and filler 0-50. Bisallylcarbonate-triethylene glycol, trilyl phosphate, triallyl cyanurate, and diacrylate triethylene glycol are used as polymerizable compounds. This composition is used to overlap steel plates. The adhesive strength of the adhesive is greater than 56 kg / cm.

The disadvantage of this composition is low physicomechanical, indicators of polymeric material.

The closest to the technical essence and the achieved effect to the proposed is the polymer composition, consisting, wt.: From the homo- or copolymer BX 5-18, OEA 5580, the stabilizer 0.2-0.5, the initiator 10 0.5- 1, j. As OEA, triethylene glycol-o1, w-dimethacrylate (TGM-3), S, w-methacryl (bis-triethylene glycol; phthalate (MGF-9) or o1, and-methacryl-LIIS; -ethylene-glycol) ft /; at

15 (: 1GF-1). This composition is intended to combine sheets, profiles, pipes, and other products made from (co) polymer-oligomeric compositions.

- A curable adhesive composition (glue joint) is characterized by chemical resistance, increased heat resistance - 117-138 s, increased tensile strength -2LO-400 kgf / cm, and other properties 2.

However, adhesive strength to the metal of the surface to be protected, determined by the breaking voltage at

30 detached, insufficient.

The purpose of the invention is to improve the adhesion strength while maintaining the heat and chemical resistance of the coating.

The goal is achieved. those that Xkompozitsi polymer comprising a copolymer BX, oligoester acrylate, a stabilizer and a polymerization initiator further contains kachesvo o1 oligoester acrylates and -dimetakril (bis glycerol) phthalate or a mixture of oligoester acrylates, vybrannam from the group consisting of triethylene-c, JO-dimetakpilat , L, uJ-methacrylic - (, bis-triethylene glycol) phthalate, L, u) -methacryl- (bis-ethylene glycol) phthalate and b, w-meth: acrcl- (bis diethylene glycol) (phthalate, in the following ratio of components, MAH: Copolymer of vinyl chloride 10-40 o (-, and) -dimethacryl (bis-glycerin) phthalate or its mixture with oligoether acrylate selected from

Use in the composition of the polymer composition OEA-TMGF-I or its mixture with OEA (GGM-3, MGF-1, MGF-9, MDF-1) allows to significantly increase the adhesive strength to the metal of the composition. The resulting coatings are characterized by increased heat resistance (according to Vic) - up to 125-130 ° C and chemical resistance to organic solvents and hot water. Prepare the composition by mixing the components at room temperature.

The mixture is sprayed onto a metal surface with a spray gun. The polymer coating is heated by hot air (100–200 ° C) for several minutes. The adhesive strength of the polymer coating is determined according to GOST 14760-69,

The compositions and test results are shown in the table.

Claim A polymer composition comprising a vinyl chloride copolymer, oligoester acrylate, a stabilizer and a polymerization initiator, characterized in that, in order to improve the adhesive strength while maintaining the specific heat chemical resistance, it contains as oligoester acrylates cL, ω-dimetakril- (bis glycerol) phthalate or a mixture of ³³ soligoether acrylate selected from the group consisting of triethylene glycol-οί, dimethacryl-, methacryl- (bis-triethylene glycol) phthalate, оСд> -methacryl- (bis-ethylene glycols) phthalate and оС7ю-methacryl- (bis-diethylene) next with elations comrade, mae.ch .: Vinyl chloride copolymer d, uz-dimethacryl (bis-glycerol) phthalate or its mixture with oliToetheriracrylate selected from the specified group MGF-9, MDF-1 and MGF-1 (examples 1-36), taken in amounts according to the invention. Low adhesive strength is possessed by polymer coatings containing only TGM-3, MGF-9, MDF-1, MGF-1 oligoester acrylates in their compositions (examples 37, 42, 47, 152, 57, 62). The increase in the content of TMHF-11 (both individually and in a mixture with FGM-3, MGF-9, MDF-1,. MGF-1) in the composition of polymer compositions leads to a decrease in the adhesive strength of the resulting polymer coatings (examples 38, 40, 43, 45, 55, 58, 60, 63, 64, 65). When the amount of TMGF-11 is increased, both in the mixture and with THM-3, MGF-1, MDF-1), positions that are not capable of spraying 50 are formed (examples 39, 41, 44, 46, 49, 51, 54, 56, 59, 61, 66, 67, 68).
