이때, 사용되는 인조석 원료(Base Binder Paste)는 통상의 인조석 제조에 사용되는 수지(아크릴 등) 및 시멘트 페이스트일 수 있으며, 사용자의 취향에 따라 다양한 색상으로 선택될 수 있다.At this time, the artificial stone material (Base Binder Paste) used may be a resin (acrylic, etc.) and cement paste used in the manufacture of ordinary artificial stone, it may be selected in various colors according to the user's taste.

마지막으로, 양생 및 탈형 후, 시트박리 또는 통상의 표면연마 작업을 거쳐, 시트(70)는 제거되고 칩(80)만 남아 다양한 외관 디자인을 갖는 인조석 완제품(11)을 얻을 수 있다. 즉, 시트(70)는 제거되어 인조석 완제품(11)에는 존재하지 않으 며, 칩(80)만 존재하여 다수의 칩(80)의 조합으로 다양한 외관 디자인을 표현하게 된다.Finally, after curing and demolding, through sheet peeling or normal surface polishing, the sheet 70 is removed and only the chip 80 remains to obtain an artificial stone finished product 11 having various appearance designs. That is, the sheet 70 is removed and does not exist in the artificial stone finished product 11, only the chip 80 is present to represent a variety of appearance design by the combination of a plurality of chips (80).

[실시예]EXAMPLE

칼라유리와 천연석 칩을 이용하여 시멘트계 인조석을 제조하였다.Cement artificial stone was manufactured using color glass and natural stone chips.

먼저, PET 필름 위에 미리 도안된 별모양의 스크린샤를 올려놓고, 그 위에 PVC 졸을 투입한 다음, 스퀴지(Squeegee)로 밀어 PET 필름 위에 별모양의 PVC 졸을 전이시켰다.First, the star-shaped screenshasa previously designed on the PET film was placed, a PVC sol was placed thereon, and then pushed into a squeegee to transfer the star-shaped PVC sol onto the PET film.

이 위에 3 내지 6 ㎜ 정도의 칼라 유리칩을 스캐터링한 다음, PVC 졸이 없는 부분에 스캐터링된 여분의 칼라 유리칩을 털어낸 다음, 180℃ 오븐에 5분간 넣어 PVC 졸을 겔링시켰다. PVC 졸의 겔링이 끝난 후 접착되지 않은 여분의 칼라 유리칩을 추가로 털어내었다.After scattering the colored glass chips of about 3 to 6 mm on top of them, the extra colored glass chips scattered on the PVC sol-free part were shaken off and placed in an oven at 180 ° C. for 5 minutes to gel the PVC sol. After gelling of the PVC sol was completed, additional non-glued color glass chips were further shaken off.

이렇게 얻어진 PET 시트를 450㎜L×450㎜W×30㎜T 몰드에 천연석 칩이 위로 향하도록 올려놓은 다음, 인조석의 바인더가 되는 시멘트 페이스트를 투입하였다. 이때, 사용되는 시멘트 페이스트는 시멘트 100 중량부에 1 내지 9 ㎜ 정도의 천연석 칩 300 내지 370 중량부, 천연석분(#100 내지 #350) 30 내지 100 중량부, 물 25 내지 35 중량부, 감수재 1 내지 3 중량부로 조성하였다.The PET sheet thus obtained was placed on a 450 mm L x 450 mm W x 30 mm T mold with the natural stone chip facing upwards, and then a cement paste serving as a binder of artificial stone was added. At this time, the cement paste used is 300 to 370 parts by weight of natural stone chips of about 1 to 9 mm, 30 to 100 parts by weight of natural stone powder (# 100 to # 350), 25 to 35 parts by weight of water, and water-reducing material. The composition was 1 to 3 parts by weight.

시멘트 페이스트를 몰드에 넣고 진동장치를 이용하여 1 내지 5분간 진동을 가하여 시멘트 페이스트 내에 있는 기포를 제거한 다음, 온도 40 내지 50℃ 및 항습이 유지되는 조건에서 12시간 동안 양생시켰다.The cement paste was placed in a mold and subjected to vibration for 1 to 5 minutes using a vibrator to remove bubbles in the cement paste, and then cured for 12 hours under conditions of maintaining a temperature of 40 to 50 ° C. and humidity.

양생이 완료된 후, 몰드에서 꺼내어 통상의 인조석 연마 및 재단과정을 거쳐 400㎜L×400㎜W×20㎜T의 표면에 칼라 유리의 별모양을 갖는 인조석을 얻었다. 연마시 주의할 점은, 반드시 칼라 유리칩(3 내지 6 ㎜) 이하로 연마를 해야 한다.After curing was completed, it was taken out of the mold to obtain artificial stone having a star shape of colored glass on the surface of 400 mm L x 400 mm W x 20 mm T through a normal artificial stone polishing and cutting process. In polishing, care should be taken not less than the color glass chips (3 to 6 mm).

한편, 인조석의 디자인은 사용자의 취향에 따라 다양하게 도안될 수 있으며, 시멘트 페이스트에 사용되는 천연석 칩의 종류도 다양하게 선택할 수 있다.On the other hand, the design of the artificial stone can be variously designed according to the user's taste, it is also possible to select a variety of types of natural stone chips used in the cement paste.

상기에서 명기한 바와 같이, 본 발명은 인조석을 제작함에 있어서, 다양한 디자인의 칩시트를 이용하여 차별화된 외관을 표현함으로써 사용자의 취향에 맞는 미려한 외관을 제공하는 동시에 제품의 신뢰성을 향상시키는 등의 유용한 효과가 있다.As stated above, the present invention provides a beautiful appearance to the user's taste by improving the reliability of the product by expressing a differentiated appearance using a chip sheet of various designs in manufacturing artificial stone It works.
