Description

The invention relates to two-layer sealing materials and can be applied. For sealing and sealing joints of prefabricated buildings and structures.

The purpose of the invention is to increase the viability, plasticity and fire resistance of the material.

To obtain a sealant, butyl rubber, high molecular weight polyisobutylene and ethylene propylene EPM-5 rubber are used. The curing system is parahinodioxime and manganese dioxide, which is triggered when the layers are mixed in an electrical sealer. The filler is chalk. the plasticizer is industrial oil. The thixotropic additive, which reduces the fluidity of the sealant from vertical and ceiling surfaces, is represented by aerosil or asbestos.

Complex additive contains bischofite, potassium chloride and kaolin.

Sealant consists of two., Interconnected layers. The composition of the first layer includes; high molecular weight polyisobutylene, paraquinone dioxime, filler, thixotropic additive and plasticizer. The second layer contains: butyl rubber. manganese dioxide, a filler, a thixotropic additive, a plasticizer and a complex additive, including bischofite. potassium chloride and kaolin.

Formulations of the compositions of the material are presented in table. 1. The preparation of sealants is carried out as follows.

example (composition 1, table. 1).

Preparation of the first layer.

In the mixer, equipped with Z-shaped blades, load 100 wt.h. high molecular weight polyisobutylene of the P-118 brand and portions of 100 wt.h. industrial oil brand I-30. The mass is stirred for 1 hour until homogeneous, after which 100 wt.h. chalk and 3 ma.ch. aeroeil and the mass is stirred for 1.5 hours. Then 1 wt.h. parahinondioxime. From the obtained composition, the first layer of a gertic is formed in the form of a strip or ribbon.

Preparation of the second layer.

In the mixer with Z-shaped blades, 100 wt.h. pre-rolled butyl rubber brand BK1530s, 100 wt.h. ethylene-propylene rubber SKEP-5 brand 540, 100 wt.h. industrial oil I-30 and agitated for 1 hour. Then 50 wt. chalk, 3 wt.h. Aerosil, 1 wt.h. manganese dioxide, 3.3 wt.h. bischofite, 3.3 wt.h. potassium chloride and 3.3 wt.h. kaolin, stirred for 1.5 hours. From the resulting composition is molded in the form of a strip or tape the second layer of sealant. In finished form, the sealant is a material consisting of two layers interconnected. The working composition of the sealant is obtained by mixing its layers in an electro-sealer equipped with a screw of special design.

From the working composition of hermetic materials, samples are prepared which, after vulcanization, are tested for physical and mechanical properties.

Example 2 (part 2, table, 1).

Preparation of the first layer.

In the mixer load 100 wt.h. high molecular weight polyisobutylene brand P-155, 150 wt.h. industrial oil grade I-40A and mixed for 1 hour. After that, 150 wt.h. chalk and May 7, h. Aebesta and mix in 2 hours. In the prepared mass is introduced 2 wt.h, parahinodioxime. From the prepared composition is molded in the form of a strip or tape of the first layer of sealant.

Preparation of the second layer.

In the mixer is placed 100 wt.h. of the butted rubber of the brand BK1040T, 50 May, h. ethylene-propylene rubber SKEP - 5 brand 550 and portions of 150 parts by weight, industrial oil brand I40A and stirred for 1 hour, after which 100 parts by weight are loaded. chalk, 2 ma.ch. manganese dioxide, May 7, h. aebesta, 5 wt, h, bischofite, 5 wt.h. potassium chloride and 5 wt.h, kaolin and stirred for 1.5 hours. From the resulting composition is molded in the form of a strip or tape the second layer of sealant.
