Abstract
The invention relates to a preparation method of a rain vision used for auto windshield glass. The method synthesizes acrylic resin solution with good water repellency. By dissolving a certain amount of simethicone with water repellent function into polymer solution, the rain vision of the invention used for auto windshield glass which has good water repellency and adhesion performance is obtained.
Description
Technical field
The invention belongs to field of fine chemical, relate to the manufacture method of vehicle glass with antirain agent.
Background technology
Automobile needs the water of scraping that rain brush do not stop when travelling in the rainy day, not stopping of rain brush movingly can be disturbed driver's sight line, dewaters untotally because of rain brush again, and the transparency of windshield is obviously reduced, and has also influenced driver's sight line, has increased the difficulty of safety traffic.
In order to address this problem, people have developed some automobile wind shield glass antirain agents, are mostly that the dimethyl silicone oil that water repellency is very strong is dissolved in the organic solvent to obtain.Though have waterproof effect preferably, its sticking power is little, will be ineffective when rain drop erosion and truck washing, and the usage period is very short.
Summary of the invention
The present invention has also improved the sticking power of antirain agent to windshield when guaranteeing that antirain agent has good water repellency.Its method is with the water repllents of a certain amount of methyl-silicone oil as 3-8% and so on, is dissolved in the macromolecular solution with certain water resistance.This polymer confrontation windshield has good sticking power, and can be in the uniform coating of formation on glass.This coating is fixed on dimethyl silicone oil and so on water repllents in the coating again.Therefore both increased rainproof effect, and made rainwater become droplet to tumble, and can not come off again, greatly facilitated driver's driving because of washing away.
So the macromolecular solution among the present invention has the water repellency of height, be because adopt the vinylformic acid high alcohol ester as: Octyl methacrylate and other vinyl monomer as: vinylbenzene etc. have the material of outstanding hydrophobicity performance, form by solution copolymerization.In order to obtain to have the macromolecular material of enough tenacityes, the consumption of Octyl acrylate is between 20 one 40%, and the styrene monomer consumption is at 60-80%.
For dimethyl silicone oil can be dissolved in the macromolecular solution fully, when the macromolecular solution polymerization, must select for use is the good solvent of macromolecular material, is again the good solvent of dimethyl silicone oil, and the present invention selects the toluene kind solvent for use.
In order to obtain enough big molecular weight to guarantee good film performance, can guarantee carrying out smoothly of solution polymerization again, toluene kind solvent consumption is unsuitable too much, is advisable with the 15-40% of reaction monomers amount.
As initiator, with Diisopropyl azodicarboxylate for well.The gained macromolecular material degree of branching is low, the transparency height that gained is filmed.Consumption is the 2-5% of amount of monomer.
Embodiment
The high molecular polymerization prescription:
Octyl methacrylate 80
Vinylbenzene 120
Toluene 60
Diisopropyl azodicarboxylate 5
Converging operation:
Octyl methacrylate, vinylbenzene and Diisopropyl azodicarboxylate is miscible good 1..
2. the toluene with formula ratio adds in the four-hole bottle.
3. use the nitrogen wash reaction flask, and make it to react end always.
4. after being warming up to 80-85 ℃, evenly drip mixed reaction monomers 1, in three hours, add.
5. continue reaction after three hours, cooling discharge.
The preparation of antirain agent:
With above-mentioned gained macromolecular solution with 3000 the gram dilution with toluene to solid content between 5-8%.
2. dimethyl silicone oil 120 grams are dissolved in 1 solution that obtains and get final product.
Claims (3)
1. automobile wind shield glass antirain agent.It is characterized in that dimethyl silicone oil miscible to having in the acrylic resin soln of well refusing the water effect.
2. antirain agent as claimed in claim is characterized in that described polymer (by the percentage ratio of monomer total amount) composed as follows.
(methyl) Octyl acrylate 20-40
Vinylbenzene 60-80
3. rainproof profit as claimed in claim 1 is characterized in that the 20-60% of described dimethyl silicone oil consumption for back of the body molecular material.
