Abstract
The invention provides an environment-friendly drying agent with a high water absorption rate and a preparation method thereof. The drying agent is composed of the following raw materials in parts by weight: 40 to 60 parts of acrylic resin, 30 to 40 parts of acrylamide, 20 to 40 parts of polyvinyl alcohol, 5 to 15 parts of guar gum, 3 to 12 parts of nano silicon dioxide, 3 to 10 parts of nano titanium dioxide, and 1 to 5 parts of auxiliary material. The formula of the drying agent is reasonable, the preparation technology is simple, compared with the prior art, the drying speed is faster, the moisture absorption rate is higher, at the same time, the prepared drying agent is safe to the environment and human body and thus is an environment-friendly product; moreover, the stability is strong, the service life is long, and the drying agent is the best choice for drying therefor.
Description
Technical field
The present invention relates to a kind of drier, be specifically related to a kind of environmental protection height suction rate drier and preparation technology thereof.
Background technology
Drier is the goods extended the shelf life conventional in food and medicine packaging, it can make article keep relatively dry in a long time, the moisture condition of regulating and controlling microbial existence and chemical reaction, photolysis and enzymatic reaction, thus reaching protection against the tide, mildew-resistant, insect protected, the object such as antirust, this effective measures are generally applied in scientific research, production and daily life.
Drier is not all point physical absorption drier and chemisorbed drier by suction type and product.The drier of physical absorption mainly contains silica gel, alumina gel, molecular sieve, active carbon, bone black, charcoal, mineral agent, or atlapulgite etc., its drying principles be exactly by physics mode by Water Molecular Adsorption in the structure of self; The conventional drier of chemisorbed has Quick lime desiccant, magnesium chloride, calcium chloride, soda lime or phosphorus pentoxide, silicic acid etc., and they absorb hydrone by chemical mode and change its chemical constitution, becomes another material.
Although traditional drier is widely used, it also exists deficiency at aspect of performance, and not enough for these, such as water absorption rate is low, there is certain harm to health and environment, and unstable properties.
Therefore, for the problems referred to above, the present invention proposes a kind of new technical scheme.
Summary of the invention
The object of this invention is to provide a kind of environmental protection height suction rate drier and preparation technology thereof.
The present invention is achieved through the following technical solutions:
A kind of environmental protection height suction rate drier, comprises the raw material composition of following parts by weight: acrylic resin 40 ~ 60 parts, acrylamide 30 ~ 40 parts, polyvinyl alcohol 20 ~ 40 parts, guar gum 5 ~ 15 parts, nano silicon 3 ~ 12 parts, nano titanium oxide 3 ~ 10 parts, auxiliary material 1 ~ 5 part.
Further, described auxiliary material is the mixture of potassium peroxydisulfate and stearate.
Further, the mass ratio of described potassium peroxydisulfate and stearate is 1:1 ~ 2.
A kind of preparation technology of environmental protection height suction rate drier, in poly-vinyl alcohol solution, add acrylic resin and acrylamide, react 0.5 ~ 2h at normal temperatures, then add guar gum reaction 0.5 ~ 1.5h, then nano silicon, nano titanium oxide and auxiliary material is added successively, temperature controls, at 40 ~ 80 DEG C, to be uniformly mixed time controling at 2 ~ 3h, to be cooled to room temperature, suction filtration, drying, then compressing by tablet press machine, last, be ground into a class shape and namely obtain required drier.
The invention has the beneficial effects as follows: this drier formula is reasonable, preparation technology is simple, and compared with prior art, rate of drying is fast, there is very high hydroscopicity, meanwhile, prepared drier can not produce potential safety hazard to environment and human body, is the environment amenable product of a kind of environment-friendly type, and, stability is strong, long service life, is to realize dry optimal selection.
