Description
Technical field
The present invention relates to field of inorganic materials, particularly relate to a kind of rubber defoamer formula and preparation method thereof.
Background technology
Rubber defoamer, also known as rubber hygroscopic agent, vulcanization of rubber defoamer, can be used for doing in rubber and some product of rubber and plastic
Compounding ingredient, absorbs its goods moisture content that filler, vulcanizing agent, accelerator, foaming agent used etc. are brought in process of production, makes
The internal pore-free of its goods, section is uniformly, fine and close, smooth surface is attractive in appearance.The most common rubber defoamer mostly is powder
Powder so that the shelf-life of defoamer is greatly shortened, the easy moisture absorption goes bad, and is difficult to weigh.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, it is an object of the invention to provide a kind of rubber defoamer formula and system thereof
Preparation Method.
The present invention takes techniques below scheme to realize: a kind of rubber defoamer formula, described defoamer is by aoxidizing
Calcium and PE film composition, be made up of according to the raw material of weight portion percentage ratio following: calcium carbonate 2 ~ 4 parts, nucleator 1 ~ 3 part, coupling agent
1.2 ~ 1.8 parts, lubricant 0.8 ~ 1.4 part, foaming agent 0.4 ~ 0.8 part and remainder are calcium oxide.
Above-mentioned a kind of rubber defoamer formula, described defoamer is made up of calcium chloride and PE film, by following according to weight
The raw material composition of part percentage ratio: calcium carbonate 2 ~ 3 parts, nucleator 1 ~ 2 part, coupling agent 1.2 ~ 1.6 parts, lubricant 0.8 ~ 1.2 part,
Infusion 0.4 ~ 0.6 part and remainder are calcium oxide.
Above-mentioned a kind of rubber defoamer formula, described defoamer is made up of calcium chloride and PE film, by following according to weight
The raw material composition of part percentage ratio: calcium carbonate 2 parts, nucleator 1.5 parts, coupling agent 1.3 parts, lubricant 0.8 part, foaming agent 0.6 part
It is calcium oxide with remainder.
Above-mentioned a kind of rubber defoamer formula, the percentage by weight of described calcium oxide is more than 95%.
The preparation method of above-mentioned a kind of rubber defoamer formula, is prepared from by following steps:
(1) calcium carbonate, nucleator, coupling agent, lubricant and foaming agent are mixed, squeezed by die orifice is linear after spiro rod plasticizing
Go out, stretched rear formation PE film；
(2) by combine elastomer make calcium oxide become bulk；
(3) fully sealing parcel calcium oxide with PE film in dry environments, every 18kg uses the PE film packaging of 2kg；
(4) packed in cases, weighs.
The method have the advantages that this formula can well ensure that defoamer internal oxidation calcium exists in sum
It is not hydrolyzed before using, with low cost, improve storage time, the good stability of calcium oxide greatly, to be difficult to the moisture absorption rotten, easily
In weighing, moisture absorption efficiency is high, it is ensured that quality of item is stable.
Detailed description of the invention
