Abstract

FIELD: chemistry.

SUBSTANCE: invention relates to chemistry of synthetic substances - polymer substances in a mixture with organic and natural substances, for example, for urban and agricultural purposes, or to compositions for mulching different types of soil, lawn and parking areas. The mulching composition is characterised by that it contains lignosulphonate, carbamide, NA-carboxymethyl cellulose, potassium chloride and, as natural additives, Pellia endiviifolia moss and Pinus pumila pine needles, and water in the following ratios, wt %: lignosulphonate 0.1-0.4, carbamide 0.2-0.6, NA-carboxymethyl cellulose 0.3-0.4, potassium chloride 1-3, Pellia endiviifolia moss 10-15, Pinus pumila pine needles 8-9, water - the balance. Other versions of polymer-natural mulching compositions are also disclosed.

EFFECT: wider range of soil mulching compositions.

Description

The invention relates to the chemistry of synthetic substances - polymeric mixed with organic and natural substances, for example, for urban and agricultural purposes or to compositions for mulching various types of soils, lawns, park areas.

Previously, such a mulching coating composition was known in which polyacrylamide, urea, lignosulfonate, potassium chloride and water were used, in the following ratio, wt.%: Polyacrylamide 0.25-0.75, lignosulfonate 0.5-1.5, carbamide 0, 4-0.8, potassium chloride 1-3, water the rest (Russian patent No. 2034899 C1, 1995, class of international classification of patents, C09K 17/00).

But such a patent did not use natural materials - this is a significant drawback. In nature, there are many materials suitable for this - many mosses, different types of wood waste: bark, shavings, wood chips. Moreover, different types of wood can be combined with different types of synthetic materials - polymers, their waste, if they are environmentally friendly.

In the invention, the technical result is the use of numerous types of natural materials, that is, the expansion of the arsenal of compositions for mulching soils.

This result is achieved in that the composition of the mulching coating according to the invention contains lignosulfonate, urea, Na-carboxymethyl cellulose, potassium chloride, and as natural additives moss of the species Pellia endiviifolia and pine needles Pinus pumila, water, wt.%:

lignosulfonate 0.1-0.4 urea 0.2-0.6 Na-carboxymethyl cellulose 0.3-0.4 potassium chloride 1-3 moss species Pellia endiviifolia 10-15 pine needles Pinus pumila 8-9 water rest.

As options, the following compositions were invented, in which important ratios for moss and needles were changed (selected):

moss species Pellia endiviifolia 10-15 pine needles Pinus pumila 9.1-9.5

or

moss species Pellia endiviifolia 10-15 pine needles Pinus pumila 9.8-11

or

moss species Pellia endiviifolia 15,5-17 pine needles Pinus pumila 8-9

or

moss species Pellia endiviifolia 17.8-18 pine needles Pinus pumila 8-9

or

moss species Pellia endiviifolia 17.1-18 pine needles Pinus pumila 9.8-10

or

moss species Pellia endiviifolia 17.8-18 pine needles Pinus pumila 10.6-11

or

moss species Pellia endiviifolia 17.8-18 pine needles Pinus pumila 11,2-12

or

moss species Pellia endiviifolia 17.8-18 pine needles Pinus pumila 12.1-12.8

The composition is prepared as follows.

These ingredients are individually milled and then mixed in an aqueous medium.
