Description

The invention relates to polymer concrete mixtures and can be used for the manufacture of building structures and anti-corrosion protective coatings.

The aim of the invention is to increase the modulus of elasticity, reduce volumetric shrinkage and increase the coefficient of chemical resistance in a 15% caustic soda solution after 6 months. pegs

The method for preparing the mixture is as follows.

These polymer compositions are made by hand using the following sequence: the quartz filler and manganese peroxide are dried in a heating cabinet at 100 ° C for 5 hours, after which they are cooled to a normal temperature (20-15 ° C), the required amount of each polymer component is measured by measuring composition. Then, a measured amount of polyester resin, cobalt naphthenate is poured into a clean mixer, then manganese peroxide (in the amounts shown in Table 1) is added and mixed until the mass is uniform in color. The required amount of the modified agloporite, quartz napoltep is introduced into the mixture and mixed thoroughly. Agloporite modification

carried out by mixing in a siccative toluene solution to a maximum weight gain, the siccative had the following composition;

in a molar ratio of 1: 1.

A siccative was used in the form of a toluene solution with a concentration of 10 g / l.

The prepared mixture is placed in a special steel form. Seal the mixture in the form of a bayonet at 20 ° C.

After 1 day. curing the finished samples is removed from the molds and heated at 8 hours, after which physical and physical tests are carried out.

The test results are shown in table 30. 2

The samples were tested in the form of prisms 4-4 16 cm in size of the following compositions.
