Description
Technical field
The invention belongs to sanitary ware technical field, and in particular to a kind of lavatory lid and preparation method thereof.
Background technology
As the improvement of people's living standards, closestool becomes a kind of daily necessities become increasingly popular.It is best in quality, make
There is high market appealing degree and huge market potential with the closestool product of convenient, clean hygiene.Bathroom is applied at present
Lavatory lid material mainly include the traditional material such as acrylonitrile-butadiene-styrene (ABS) plastics, polypropylene, ureaformaldehyde.Wherein, third
The easy aging jaundice of alkene nitrile-butadiene-styrene plastics, corrosion-resistant；Polypropylene material surface is easily scratched, and influence is beautiful
See, while ageing resistace is poor；Embrittlement easily occurs for ureaformaldehyde, and service life is short.
Therefore, research and develop that a kind of ageing resistace is good, the lavatory lid that surface is difficult to scratch, good corrosion resistance, intensity are high, tool
It is of great significance.
The content of the invention
Turn to be yellow, easily scratch to solve the easy aging of Conventional toilets cover plate, corrosion-resistant, easy embrittlement the problems such as, it is of the invention
Purpose is to provide a kind of lavatory lid and preparation method thereof.
The present invention is achieved through the following technical solutions：A kind of lavatory lid, by weight, raw material includes：It is poly-
100 parts~200 parts of mutual-phenenyl two acid bromide two alcohol ester, 10 parts~30 parts of magnesium hydroxide, methyl methacrylate-butadiene-benzene second
20 parts~50 parts of alkene copolymer, 5 parts~10 parts of calcium carbonate.
Preferably, by weight, above-mentioned raw materials also include the present invention：10 parts~20 parts of phenyl salicylate.
Preferably, by weight, above-mentioned raw materials also include the present invention：15 parts~25 parts of APP.
Preferably, by weight, above-mentioned raw materials also include the present invention：5 parts~10 parts of sodium metasilicate.
A kind of preparation method of lavatory lid, step includes：
S1. above-mentioned raw materials are mixed in proportion, is heated at 150 DEG C~200 DEG C, obtain fused materials；
S2. fused materials are molded into lavatory lid mould, cooled down, the demoulding produces lavatory lid finished product.
Preferably, in above-mentioned steps S1, the heat time to above-mentioned raw materials is 2 hours~4 hours to the present invention.
Polybutylene terephthalate (PBT), which is that milky is translucent, arrives opaque, semicrystalline thermoplastic polyester, with height
Heat resistance, can the long-term work at 140 DEG C, toughness, fatigue durability, self-lubricating, low-friction coefficient.Magnesium hydroxide has good
Shock-absorbing capacity, adsorptivity power, be a kind of fire retardant of environmental protection.MBS
With higher intensity, it still is able to keep very high rigidity at 85 DEG C~90 DEG C, lavatory lid material can be significantly improved not
The performance easily scratched, still has good toughness at -40 DEG C, lavatory lid is not susceptible to embrittlement, and oil resistant, it is acidproof,
Alkaline-resisting, ultraviolet resistance aging.Calcium carbonate can strengthen the intensity of lavatory lid.
Phenyl salicylate can absorb ultraviolet light, it is possible to increase the performance of the anti-aging jaundice of lavatory lid.
APP is nonpoisonous and tasteless, does not produce etchant gas, and heat endurance is high, it is possible to increase the intensity of lavatory lid and resistance to
Corrosion.
Sodium metasilicate cohesive force is strong, with higher intensity, it is possible to increase the corrosion resistance of lavatory lid, heat resistance and water-fast
Property, improve anti-aging, the erosion-resisting performance of lavatory lid.
The present invention can at least reach less than one beneficial effect：
1. ageing resistace is high, jaundice is difficult, can keep profile fair and clear attractive in appearance for a long time；
2. with high intensity, it is difficult to scratch, is difficult embrittlement；
3. decay resistance is high, service life is long；
4. preparation method is simple, the cost of raw material is cheap.
