Abstract
The invention relates to a display rear shell with waterproof and fireproof properties comprising a main layer of a pulp made from hardwood in an amount from 80% to 90% by weight of the main layer, a pulp waterproof composition in an amount from 5% to 15% by weight of the main layer, and a flame retardant in an amount of a remaining weight percentage by weight of the main layer, a fireproof layer and a waterproof layer, in place of a traditional plastic display rear shell using plastic materials for characteristics as waterproof, fireproof and light weight.
Claims15
A display rear shell with waterproof and fireproof properties comprising:
- a main layer having a pulp in an amount from 80% to 90% by weight of the main layer, a pulp waterproof composition in an amount from 5% to 15% by weight of the main layer, and a flame retardant in an amount of a remaining weight percentage by weight of the main layer, wherein:
- the pulp is made from hardwood;
- the pulp waterproof composition comprises a waterproof agent having a PH value ranging from 7 to 9 in an amount from 5% to 8% by weight of the pulp waterproof composition and a glue in an amount of a remaining weight percentage by weight of the pulp waterproof composition, wherein the waterproof agent comprising a synthetic beeswax in an amount from 25% to 35 wt. % by weight thereof;
- and
- the flame retardant is a phosphorus flame retardant, a halogenated flame retardant, an alumina hydrated flame retardant, a borax flame retardant or combination thereof, and
- wherein said display rear shell comprises a rear shell of an LCD display panel.
A method for manufacturing a display rear shell with waterproof and fireproof properties comprising the steps of:
- step one:
- mixing a pulp, a pulp waterproof composition, and a flame retardant to form a concentrated pulpiness as an essential raw material for production of a main layer of the display rear shell, wherein the main layer includes a pulp made from hardwood in an amount from 80% to 90% by weight of the main layer, a pulp waterproof composition in an amount from 5% to 15% by weight of the main layer, and a flame retardant in an amount of a remaining weight percentage by weight of the main layer;
- step two:
- filling the concentrated pulpiness into a mold, and pressing it to form the main layer of the display rear shell;
- and
- step three:
- drying the main layer of the display rear shell for finished product of a display rear shell with waterproof and fireproof properties and,
- wherein said mold forms a rear shell of an LCD display panel.
