RU2476488C1 - Mulching composition - Google Patents

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, Tetraphidopsida moss and Thuja orientalis 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, Tetraphidopsida moss 10-15, Thuja orientalis needles 8-9, water - the balance. Other versions of the mulching composition have different content (wt %) of moss and needles.

EFFECT: enabling use of natural materials which can be combined with different types of synthetic polymer materials and wastes thereof if they are not harmful to the environment.

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 known was the composition of the mulching coating 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, M.cl. 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, 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 this 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 Tetraphidopsida and needles of Thuja orientalis, water in wt.%:

lignosulfonate 0.1-0.4 urea 0.2-0.6 Na-carboxymethyl cellulose 0.3-0.4 potassium chloride 1-3 Tetraphidopsida moss 10-15 Thuja needles Thuja orientalis 8-9 water rest.

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

Tetraphidopsida moss 10-15 Thuja needles Thuja orientalis 9.1-9.5

or

Tetraphidopsida moss 10-15 Thuja needles Thuja orientalis 9.8-11

or

Tetraphidopsida moss 15,5-17 Thuja needles Thuja orientalis 8-9

or

Tetraphidopsida moss 17.8-18 Thuja needles Thuja orientalis 8-9

or

Tetraphidopsida moss 17.8-18 Thuja needles Thuja orientalis 9.8-10

The composition is prepared as follows.

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