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, urea 0, 4-0.8, potassium chloride 1-3, water - the rest (Russian patent No. 2034899 C1, 1995, class of international classification of patents С09К 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, various 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 harmless to the environment.

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 by the fact 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 larch needles Larix lyallii, water in the following 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 needles of larch Larix lyallii 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 needles of larch Larix lyallii 9.1-9.5

or

moss species Pellia endiviifolia 10-15 needles of larch Larix lyallii 9.8-11

The composition is prepared as follows.

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

The table shows various examples for the variants of the invention:
