RU2476579C1 - Mulching composition - Google Patents

Abstract

FIELD: chemistry.

SUBSTANCE: invention relates to the technology of producing compositions for mulching different types of soil, lawn and parking areas. The aqueous mulching composition contains lignosulphonate, carbamide, Na-carboxymethyl cellulose, potassium chloride and, as natural additives, Tetraphidopsida moss and Juniperus virginiana 'Skyrocket' juniper needles, in different amounts which are reflected in versions of the polymer-natural mulching composition.

EFFECT: use of said compositions improves 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, 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, carbamide, Na-carboxymethyl cellulose, potassium chloride, and as natural additives moss of the Tetraphidopsida species and juniper needles Juniperus virginiana 'Skyrocket', 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 juniper needles Juniperus virginiana 'Skyrocket' 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 juniper needles Juniperus virginiana 'Skyrocket' 9.1-9.5

or

Tetraphidopsida moss 10-15 juniper needles Juniperus virginiana 'Skyrocket' 9.8-11

or

Tetraphidopsida moss 15,5-17 juniper needles Juniperus virginiana 'Skyrocket' 8-9

or

Tetraphidopsida moss 17.8-18 juniper needles Juniperus virginiana 'Skyrocket' 8-9

or

Tetraphidopsida moss 17.8-18 juniper needles Juniperus virginiana 'Skyrocket' 9.8-10

The composition is prepared as follows.

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