Description

 The invention relates to the technology of building materials, to the compositions of monolithic coatings for the upper structural layers of floors of industrial buildings.

Also known is the fire-retardant polymer composition selected for the prototype for flooring based on epoxy oligomer (as film-forming), low molecular weight polybutadiene rubber (as modifier), mineral filler, polyethylene polyamine (as hardener), as well as trichlorodiphenyl and chlorine paraffin Parachlor-380 ( as plasticizers) in combination with additives of α-hydroxyethylferrocene and pentabromophenol chlorohydrin ether (as flame retardants) in the following ratios of components, wt.%:
Epoxy Dianne Resin - 31.25 - 36.50
Low molecular weight polybutadiene rubber with a mol.m. 2000-3000 - 1.30 - 3.29
Trichlorodiphenyl - 7.30 - 9.38
Chloroparaffin - 3.51 - 4.69
Polyethylenepolyamine - 3.12 - 5.26
Pentabromophenol chlorohydrin ester - 6.62 - 9.15
α-hydroxyethylferrocene - 0.03 - 0.16
Mineral Filler - Else
[SU 1548196 A1, B.I. N 9, 1990].

 The composition has good physical and mechanical properties, however, the halogen-containing components used in it do not provide high fire resistance values (for epoxy coatings KI> 40%).

 The objective of the invention is to develop a polymer composition for coating with reduced combustibility, while maintaining a high level of technological and physico-mechanical properties of the composition based on available industrial raw materials.

The task is achieved by the development of a polymer composition for bulk coatings containing a film-forming, modifier, plasticizer, hardener, bromine-containing flame retardant and a mixture of mineral fillers. As a film-forming agent, it contains an ED-20 brand epoxy resin, three TGM-3 grade (oxyethylene) dimethacrylate modifiers, XP-470 grade chloroparaffin (TU 6-01-568-76) or a mixture of dioxane alcohols, or of their high-boiling esters of the "Plasticizer Edos" brand (TU 2493-003-13004749-93), as a hardener - polyethylene polyamine, as a bromine-containing flame retardant - decabromodiphenyl oxide, as a mineral filler - aluminum hydroxide and antimony trioxide at a mass ratio of antimony trioxide, hydroxide luminium and decabromodiphenyl oxide 1: (8-10): (3-5), respectively, in the following ratio of composition components, wt.%:
Epoxydian resin - 32.70 - 42.10
Tri (hydroxyethylene) dimethacrylate - 6.31 - 8.66
Plasticizer - 3.93 - 6.54
Polyethylene polyamine - 5.23 - 6.20
Bromine flame retardant - 8.83 - 16.92
Mineral filler:
aluminum hydroxide - 26.25 - 29.41
antimony trioxide - 2.93 - 3.38
The invention is illustrated by the following examples.

 Example 1

 100 kg of ED-20 brand epoxy are mixed in a glue mixer for 2-3 minutes with 20 kg of three (hydroxyethylene) dimethacrylate TGM-3 and 10 kg of chloroparaffin. Into the resulting composition, 30.45 kg of decabromodiphenyl oxide, 7.51 kg of antimony trioxide and 71.06 kg of aluminum hydroxide are added and additionally mixed for another 3-4 minutes until a homogeneous mass is formed. Before application, 15.36 kg of polyethylene polyamine are added to the resulting composition, and after 2-3 minutes of mixing, they are applied to the floor surface.

 Example 2

 Similarly for the composition with a plasticizer brand "Edos Plasticizer".

 The compositions and properties of the obtained coatings are shown in tables 1, 2.

 As can be seen from the above examples, coatings obtained on the basis of the proposed composition have reduced flammability and high physical and mechanical properties. T
