Description
Technical field
The present invention relates to sizing agent preparing technical field, particularly relate to a kind of preparation method of calcium hydroxide sizing agent.
Background technology
Along with the raising of people's living standard, the demands such as various furniture and adornment get more and more.Can use sizing agent in a large number in the product processing such as furniture and adornment, and sizing agent common mostly on the market is adhesive made of synthetic resin.Can free formaldehyde be distributed in such sizing agent use procedure, human body is worked the mischief.Along with the enhancing of people's environmental consciousness, need a kind of sizing agent that can be used for green, environmental protection people badly.
Inorganic adhesive bonding strength is high, water-tolerant, but its fragility is large, plane docking, overlap joint, impact, stripping strength is all lower.Natural polymer sizing agent, nontoxic, safety, but water tolerance and gumminess poor, cause it in disfavor in actual application.The invention discloses a kind of method that natural polymer and calcium hydroxide compound prepare novel adhesive.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of preparation method of calcium hydroxide sizing agent, can solve existing sizing agent and there is Form aldehyde release, the problems such as contaminate environment more.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the preparation method providing a kind of calcium hydroxide sizing agent, comprises the steps:
(1) vegetable-protein pre-treatment: taking 250 ~ 400 parts of granularities is 80 object starch and soyflours, puts into the mixed solution of clorox and hydrogen peroxide, 50 DEG C of constant temperature, 1000 revs/min, reaction 3 ~ 5h; Take 20 ~ 30 parts of polyvinyl alcohol and above-mentioned solution put into by 30 ~ 50 parts of acrylamides, reaction 2 ~ 4h;
(2) ethanol increases glutinous: mixed solution obtained in step (1) is cooled to 40 ~ 50 DEG C, slowly adds ethanolic soln under certain condition, reaction 3 ~ 4h;
(3) tackiness agent allotment: the solution naturally cooling obtained by step (2), adds 50 ~ 60 parts of calcium hydroxides, with 1000 revs/min of stirring velocitys, under 50 DEG C ~ 70 DEG C temperature condition, stir 1 ~ 2h, naturally cool to room temperature, place 2 ~ 3h, be described calcium hydroxide sizing agent.
In a preferred embodiment of the present invention, in described step (1), described starch and soyflour mixing quality ratio are 1 ~ 3:2 ~ 5.
In a preferred embodiment of the present invention, in described step (1), described clorox and hydrogen peroxide mixed volume ratio are 2 ~ 3:5 ~ 7.
In a preferred embodiment of the present invention, in described step (2), described reaction conditions is stir 30min with the stirring velocity of 800r/min, is then rapidly heated to 70 ~ 80 DEG C, isothermal reaction 2h; It is 3 ~ 5ml/min that ethanolic soln adds speed.
The invention has the beneficial effects as follows: the preparation method of a kind of calcium hydroxide sizing agent of the present invention, by the proportion design of material choose reasonable and science, make prepared calcium hydroxide sizing agent green, environmental protection, water tolerance and gumminess are all met the need of market, and preparation technology is simple, to environment without harm.
