The specific embodiment

As shown in the figure, a kind of preparation method of imitative stone lampshade is included in and carries out blank forming in the particular model, polishes, polishes, applies at concave surface the step of glass fiber net behind the blank forming again; It is characterized in that: before step 30 blank forming, carry out the thermoplastic sheet that step 10 obtains the suitable thermoplasticity stone coagulum of thickness; Carry out step 20 again and thereby thermoplastic sheet is carried out the blanket 5 that cutting obtains lampshade body by the shape of lampshade body, the expansion pattern of size; In step 30 blank forming, blanket 5 places particular model to be subjected to the thermoforming cooling curing demoulding then then; Before step 50 pair base substrate convex surface is polished, fill the slit of base substrate convex surface 92 with resin.

By the sequence of operation, comprise 10,20,30,40,50 5 steps successively to end 99 certainly beginning 01.Wherein:

Step 10 is thermoplastic sheets of obtaining the suitable thermoplasticity stone coagulum of thickness; An its optional method comprises step by step 06 and step by step 07, wherein:

Step by step 06, be to be cast to after stone and thermoplastic resin are mixed to condense in the mould to obtain the thermoplasticity cube that constitutes by stone and the mutual coagulation of thermoplastic resin;

Step by step 07, thus be to obtain thermoplastic sheet to cutting from 06 resulting thermoplasticity cube step by step;

In addition, also can select outsourcing or go out thermoplastic sheet with identical material direct pouring.

Step 20 is that the expansion pattern of shape, size by lampshade body 9 carries out (being equivalent to the sheet metal blanking) to thermoplastic sheet thereby cutting obtains the blanket 5 of lampshade body.On Fig. 2, blanket 5 is divided into four parts by dotted line among the figure, and these four parts can keep a little and connect and compose an integral body, also can distinguish cutting.In addition, if the size of lampshade body 9 is little and the song of blanket 5 in blank forming becomes less, then blanket 5 can be divided into three parts; If the size of lampshade body 9 is big and the song of blanket 5 in blank forming becomes bigger, then need blanket 5 is divided into more umber.

Step 30 is blank formings, is about to blanket 5 and places particular model (can adopt existing model) to be subjected to the thermoforming cooling curing demoulding then then, thereby obtain base substrate.The shape of the shape of base substrate and product 9 is similar, and its convex surface 92 is more coarse than concave surface 91.

Step 40 is that base substrate is carried out following operation: the slit (its method can be brushing or injection) of filling convex surface 92 with resin (preferred non-thermoplastic resin); At the flat minimum layer of glass fiber net brushing resin (preferred non-thermoplastic resin) and leave standstill and treat resin solidification again that covers of concave surface 91.
