Abstract
The invention relates to the technical field of building material additives, in particular to a gypsum additive, including in percent by weight: 25-35% of a naphthalene-based superplasticizer, 13-18% of sodium lignosulfonate, 30-43% of an aliphatic water-reducing agent, 3-7% of anhydrous sodium sulfate and 10-18% of calcium carbonate, preferably, 30% of the naphthalene-based superplasticizer, 15% of the sodium lignosulfonate, 35% of the aliphatic water-reducing agent, 5% of the anhydrous sodium sulfate and 15% of the calcium carbonate. The technical scheme provided herein has the advantage that a gypsum article added with the additive of the invention has smooth surface, hard texture, improved wear resistance and more than doubled flexural strength compared to pure water gypsum articles.
Description
Technical field
The present invention relates to additives for building materials technical field, be specifically related to a kind of gypsum additives.
Background technology
Additive account for consequence in building materials of gypsum, contains multiple additives in a lot of products, can meet various demand.
Its key performance of the building materials of gypsum of different series is determined by additive.Improve Gypsum Fibrosum performance by additive, meet Gypsum Fibrosum and produce
The demand of product is one of important channel promoting gypsum industry development.
Gypsum additives mixes in dihydrate gypsum, semi-hydrated gypsum, anhydrous gypsum or semi-hydrated gypsum with anhydrous gypsum mixed phase
Organic or inorganic material, to change gypsum dehydration or hydration reaction, and the physical and mechanical property of gypsum hardenite, meet each row
The demand of industry application Gypsum Fibrosum, addition content is generally no greater than 5% (except special circumstances) of Gypsum Fibrosum weight.
Existing gypsum additives water-reducing rate in gypsum system is low, and slurry fluidity gradual loss is big, and the inconspicuous grade of reinforced effects lacks
Fall into.
Summary of the invention
In order to solve problem of the prior art, the invention provides a kind of quality hard, the gypsum additives of High anti bending strength.
Technical scheme of the present invention is as follows:
A kind of gypsum additives, including naphthalene series high-efficiency water-reducing agent, sodium lignin sulfonate, aliphatic water reducing agent, Matrii Sulfas Exsiccatus and carbonic acid
Calcium, each constituent content is as follows: naphthalene series high-efficiency water-reducing agent 25-35wt%, sodium lignin sulfonate 13-18wt%, aliphatic water reducing agent
30-42wt%, Matrii Sulfas Exsiccatus 3-7wt%, calcium carbonate 10-18wt%.
Preferably: each constituent content of gypsum additives is as follows: naphthalene series high-efficiency water-reducing agent 30wt%, sodium lignin sulfonate 15wt%,
Aliphatic water reducing agent 35wt%, Matrii Sulfas Exsiccatus 5wt%, calcium carbonate 15wt%.
The technical scheme that the present invention provides has the benefit that
Additive of the present invention solves original additive about phases such as water-reducing rate, intensity, slurry fluidity, the porosity, water absorption rates
The problem that mutually discord is in harmonious proportion, adds the plastering of additive of the present invention compared with pure water plastering, smooth surface, quality
Hard, anti-wear performance improves, and rupture strength improves more than 2 times.
