Description
Technical field
The present invention relates to hot melt adhesive and preparation method thereof field, particularly self-vulcanizing light fixture glue and preparation method thereof.
Background technology
Be accompanied by the fast development of Domestic Automotive Industry, bigger innovation has taken place in Automobile Design theory and technology, requires also improving constantly.At present China's car light industry is used has hot-melting type sealer and single-component organic silicon sealer, ketoxime removing type is arranged, dealcoholizing-type and depickling type sealer, depickling type organosilicon sealant respectively.Because smell is corrosive greatly, ketoxime removing type organosilicon sealant curing speed is slow, and preservation period is short, shortcomings such as bad adhesion, thus be difficult to set foot in the fast development of automobile industry.
Summary of the invention
To the deficiency of prior art, the present invention provides a kind of and has good high-low temperature resistant, and has the self-vulcanizing light fixture glue of long construction open hour.
For realizing above-mentioned purpose, the present invention adopts following technical scheme to realize:
A kind of self-vulcanizing light fixture glue, the component meter is made up of following component by weight:
Described self-vulcanizing light fixture glue,, it is characterized in that the component meter is made up of following component by weight:
Described base polymer is selected for use: hydroxyl endblocked polydimethylsiloxane.
Described reinforced filling is made up of 40% zeyssatite and 60% silica powder.
Described catalyzer is selected for use: methyltrimethoxy silane.
Described linking agent is selected for use: methyltrimethoxy silane.
Described pigment is made up of 90% organic mixing colorant and 10% white titanium pigment.
The method of manufacture of self-vulcanizing light fixture glue is made up of following steps:
A. base polymer and reinforced filling are mixed, put into vacuum kneader heating and stirring to 100～120 ℃, stir dehydration 2～3 hours, to remove moisture content wherein;
B. mixture being ventilated is cooled to below 50 ℃, and the base polymer adding catalyzer, linking agent, the pigment that have taken off water in the above-mentioned steps were mixed 2 hours, vacuumizes, and reaches fully and mixes.
Described vacuumizing, its vacuum degree control is more than 0.08mpa.
It is material of main part (being called 107 Zylox in the hydroxyl endblocked polydimethylsiloxane industry) that the present invention adopts with the hydroxyl endblocked polydimethylsiloxane; Two key appetite are little in this base polymer molecular structure; Side group is the little methyl of volume on the molecular chain; Help molecular arrangement tight, this structure makes unique water tolerance, temperature tolerance and remarkable stability to aging.Linking agent is the indispensable scarce component of preparation sealer; It can influence its set time; Being chosen in the sealer of linking agent is most important, in the technical scheme of the present invention, adopts methyltrimethoxy silane as linking agent (being called silane WE22 in the methyltrimethoxy silane industry); Methyltrimethoxy silane improves the set time of sealer, strengthens cohesive strength.Reinforced filling of the present invention adopts 40% zeyssatite and 60% silica powder to form, and it is small to adopt this combination to have a particle, good dispersivity, advantages such as enhancement.
Beneficial effect of the present invention is: the present invention a kind ofly has good high-low temperature resistant, and has the car light glue of long construction open hour.At room temperature promptly curable, set time is short and have advantages such as good cementability, stopping property, water-fast, proof voltage puncture, weather ultraviolet ageing, and it is extremely convenient to use.Sealing glue can not pollute surrounding environment from producing to use.
