RU2476574C1 - Mulching composition - Google Patents

Abstract

FIELD: chemistry.

SUBSTANCE: mulching composition is characterised by that it contains lignosulphonate, carbamide, NA-carboxymethyl cellulose, potassium chloride and, as natural additives, Bryopsida moss and Juniperus virginiana 'Springbank' juniper 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, Bryopsida moss 10-15, Juniperus virginiana 'Springbank' juniper needles 8-9, and water - the balance. Other versions of the mulching composition have different content (wt %) of moss and juniper 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, 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 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 Bryopsida and juniper needles Juniperus virginiana 'Springbank', water, wt.%:

lignosulfonate 0.1-0.4 urea 0.2-0.6 Na-carboxymethyl cellulose 0.3-0.4 potassium chloride 1-3 moss of the species Bryopsida 10-15 juniper needles Juniperus virginiana 'Springbank' 8-9 water rest.

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

moss of the species Bryopsida 10-15 juniper needles Juniperus virginiana 'Springbank' 9.1-9.5

or

moss of the species Bryopsida 10-15 juniper needles Juniperus virginiana 'Springbank' 9.8-11

The composition is prepared as follows.

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

The table provides various examples for embodiments of the invention.
