Description

A kind of decorative sheet and manufacture method thereof
The present invention relates to finishing material, particularly relate to a kind of decorative sheet.
Along with the development of society, growth in the living standard, various finishing material arise at the historic moment, and are beautifying people's life.Existing this class material has wooden decorative plate, ceramic tile, marble etc., but fearness such as wooden decorative plate is damp, inflammable, production is complicated, cost is high, smooth finish is poor; Water absorbability such as ceramic tile, marble is poor, ventilation property is poor, it is cool to send out, the process for processing difficulty is big, cost is high; The plastic plate resistivity against fire is poor, ventilation property is poor, water absorbability is poor, fold resistance is poor, surface hardness is poor, surface brightness is poor, work-ing life is short.
An object of the present invention is to provide a kind of decorative sheet with good use properties.
Another object of the present invention provides a kind of method of making above-mentioned decorative sheet.
Decorative sheet of the present invention is made with veneer by magnesium oxide, tertiary sodium phosphate, magnesium chloride, Magnesium Silicate q-agent, wood powder, tricresyl phosphate tincture ester etc.
Its manufacture method may further comprise the steps:
With MgO, Na 3PO 4, MgCl 2Mix in water, making mixed solution mother-in-law U.S. degree is 28-32 °; Mix MgO, wood powder, Magnesium Silicate q-agent thoroughly back and add in the above-mentioned mixed solution, add tricresyl phosphate tincture ester again, make plate after the stirring, spontaneous curing then, drying; Dried aforesaid substrate polishes the back and with tackiness agent veneer (as wooden skin) is pasted onboard, gets product.
Also can add sulfuric acid in the described mixed solution and make magnesium oxide and sulfuric acid reaction; Described degree Beaume can be 30-32 ° in summer, and be 28-30 ° winter; Also can add rice husk when adding wood powder; Described tackiness agent can be glue or white glue with vinyl; After making, described plate also can carry out edge sealing with moistureproof and waterproof.
The manufacture method of present invention further optimization is for to add MgO in the aqueous sulfuric acid of 40-48% (weight), making PH is 6.9-7.1, adds Na then 3PO 4To content be 9-11%, add MgCl again 3, stir, making mother-in-law U.S. degree is 28-32 °; MgO, wood powder, Magnesium Silicate q-agent are mixed the back add above-mentioned mixed solution, add tricresyl phosphate tincture ester again, make plate after the stirring, spontaneous curing, drying; Be stained with veneer then.
Also can add two-layer glass cloth before the described making sheet.
Reaction volume in the method for the present invention is decided according to the chemical reaction relation, and to react completely to best, promptly equivalent concentration is preferably identical.Used herein per-cent is all weight percent.
Used magnesium oxide, magnesium chloride are mainly as high-strength structureal adhesives in the method for the present invention; During tertiary sodium phosphate rises and diffusion; Magnesium Silicate q-agent is the talcum powder stopping composition; Wood powder (sawdust) plays filling, moisture absorption, the effect of increase toughness; Tricresyl phosphate tincture ester is a defoamer; Glass cloth plays skeleton function.
Decorative sheet of the present invention can be used as senior floor tile, sales counter decorative sheet, kitchen platen, wall slab, top ceiling etc.It has fire prevention, protection against the tide, good permeability, acid and alkali-resistance, corrosion-resistant, advantage such as surface brightness is fabulous, easy construction (paste with grout, also can stick with glue), can saw, follows closely, digs, file, and indeformable, the life-span is long.
Be that example is carried out performance comparison with decorative sheet of the present invention and like product below with the floor tile:
Table 1
Figure A9410745000041
Further specify the present invention with embodiment below.
Embodiment
Decorative sheet of the present invention is raw materials used to be:
1. magnesium oxide: white powder, form by the magniferous ore high-temperature calcination of richness, content of magnesia requires 〉=85%;
2. magnesium chloride: with the byproduct in saltern, MgCl 26H 2O content is 45-48%;
3. tertiary sodium phosphate; 4. Magnesium Silicate q-agent; 5. wood powder (sawdust); 6. glass cloth; 7. tricresyl phosphate tincture ester; 8. sulfuric acid (content 93-95%); 9. water; 10. rice husk.
Manufacturing processed is:
(1). join mixed solution
Sulfuric acid and water are put into reaction vessel, be made into the aqueous solution of sulfur acid 40-48%, the magnesium oxide that adds equivalent then stirs with the PH test paper checks that pH value is 6.9-7.1; Then with hot water with Na 3PO 4Na is poured in the said vesse in dissolving into 3PO 4Consumption is 9-11%, at last with MgCl 26H 2O adds in the described container, stirs, and treats to dissolve fully the back with the U.S. instrumentation examination of mother-in-law mother-in-law U.S. degree, and making summer mother-in-law U.S. degree is 30-32 °, and be 28-30 ° winter.
(2). join major ingredient
Get MgO (account for total amount about 60%) and put into stirrer, add wood powder and rice husk (be MgO heavy 8%) and Magnesium Silicate q-agent (magnesian 3-6%), add institute's liquid mixture prepared (consumption be about total amount 40%) after mixing thoroughly, add small amounts of phosphoric acid three tincture esters again, stirred then 10-20 minute.
(3) making sheet
With laminator making sheet on the above-mentioned material (or using mould making sheet), the plate of making is placed on smooth ventilation and carries out the spontaneous curing reaction.The initial cure time is 24-30 hour, and the curing reaction heat release notices that controlled temperature is between 25 °-60 °.Spontaneous curing drying (6-10 days summer, 10-12 days winter).
(4) lagging
Substrate that drying is good is smooth with sand papering, uses glue (white glue with vinyl also can) that the wooden skin of certain geometrical shape is pieced together onboard then.
(5) edge sealing
After the wood skin drying, with wax glue mixed solution four limits of obturaging.To make vinylbenzene wax liquid standby in order to get 8 parts of 92 parts of vinylbenzene, low paraffin (below 56 °) for method, gets unsaturated polyester 191 #Glue 20ml adds solidifying agent 1.2ml, adds vinylbenzene wax liquid 5ml again, adds promotor 1.1ml at last and mixes well all around edge sealing of back with the hairbrush brush board.
(6) gluing
Floor tile behind the edge sealing is beaten the top layer cere with sand paper, use 191 then #Twice of polyester gluing.
(7) polishing
Scrubbing brush one deck brightening agent of first-class glue, then with membrane process with 191 #To the plate face, take off to pack behind the film and get product on the polyester.
