NOVELTY - The utility model relates to the technical field of diffusion plate, especially a PS diffusion plate with anti-tearing function, comprising an upper anti-tearing plate; the upper anti-tearing plate bottom fixedly connected with a first clamping block; the first clamping block is provided with a clamping groove; the first clamping block is glidingly connected with a hollow column; the outer side of the bottom end of the hollow column fixedly connected with with a lower anti-tearing plate; the bottom end of the upper anti-tearing plate is placed with an upper graphene layer; the utility model moves the fourth clamping block; pulling the push plate to drive the second clamping block and the limiting plate to move towards the outer side; reverse the operation can protect and fix the diffusion plate; Through the optical master batch, after uniformly dispersing, it will generate secondary dispersion after passing through the upper thermoplastic resin layer and the lower thermoplastic resin layer; the light transmittance is improved greatly; by the upper graphene layer and the lower graphene layer, improving the heat conducting performance and scratch resistance of the diffusion plate; it has wide market value and is worthy of popularization.
