Description
Technical field
The invention belongs to food silica gel technical fields, and in particular to a kind of silicone baking mat with good heat-resistant aging.
Background technique
In traditional food cooking, baking operation, generallys use common paper or aluminium foil etc. and be used as boiling or baking
Food it is rebasing, or do not use it is any it is rebasing boiling, baked goods are carried out directly on baking tray, the former is carrying out boiling or baking
The process of roasting product is in, and since the time is longer, food can closely and firmly be bonded together with paper, removal trouble, even if
It can also be attached to some food epidermises during the paper being bonded on food surface is stripped, not only influence the beauty of food,
And it causes greatly to waste.Have in the prior art using silicagel pad as pad is scorched and used, can effectively avoid
It states and leads to the problem of, still, after the silicone baking mat of prior art production works long hours, it is existing that more serious heat ageing can be generated
As causing performance to be greatly lowered, can not continue to use.
Summary of the invention
The purpose of the present invention is being directed to existing problem, a kind of silicone baking mat with good heat-resistant aging is provided.
The present invention is achieved by the following technical solutions:

Afterwards, it dries to constant weight, obtains calcining nano diatomite；
(2) calcining nano diatomite obtained above is evenly spread in dipotassium hydrogen phosphate solution, is heated to 78-80 DEG C, with
250r/min revolving speed stirs 1 hour, then ultrasonication 40s, then is filtered, and washs, and drying to constant weight, obtains modification and receives
Rice diatomite；
(3) maltonic acid is soluble in water, after mixing evenly, D-Glucose acid solution is obtained, then add the salt of its quality 30%
Acid solution stirs evenly, and obtains mixed and modified liquid, and maltonic acid liquid quality fraction is 45.2%, hydrochloric acid solution mass fraction
It is 15.5%；
(4) modified Nano diatomite obtained above is evenly spread in mixed and modified liquid, under nitrogen protection, is heated to 95
DEG C, with 1800r/min revolving speed stirring 2 hours, then after cooled to room temperature, filter, cleaning, drying to constant weight to get height
Flux grape acid modified Nano diatomite.
Further, the ultrasonic power is 750W, frequency 60kHz.
Further, the rosin resin graft modification containing hydrogen silicone oil preparation are as follows: containing hydrogen silicone oil and rosin resin are pressed 35:
2.2 weight ratio is mixed to join in reaction kettle, when being heated to 100 DEG C while stirring under nitrogen protection, then adds rosin tree
The chloroplatinic acid catalyst of lipid amount 1.2 carries out reaction 30min, then keeps the temperature 1.8 hours at 122 DEG C again, naturally cools to room
Temperature to get.
The utility model has the advantages that the present invention carries out rational proportion by the raw material to silicone baking mat, the silicon haveing excellent performance can be made
The roasting pad of glue, the internal structure degree of cross linking of the silicone baking mat finished product of existing preparation is lower, easily during use, generates volatilization
Property substance and soluble substance be precipitated, when carrying out food-baking, food product can be penetrated into, the health of consumer is made
At harm, therefore the present invention passes through high-throughput grape acid by adding a certain amount of high-throughput grape acid modified Nano diatomite
Modified Nano diatomite is evenly dispersed inside silicone baking mat, and nanoparticle is combined closely with silica gel macromolecular chain, so that
